You might be surprised by how much vintage models fetch at auctions today. Collectors are eager to bid on rare pieces of history. It is not just about nostalgia; these machines represent a raw, mechanical era before digital screens. Discover if that dusty bike in your garage could actually be incredibly valuable today.

Vincent Black Shadow

There’s probably no stronger way to kick off our list than with the one and only Vincent Black Shadow. It first hit the highways in 1948 and quickly established itself as the fastest motorcycle in the world at the time. It doesn’t hurt that the thing still looks fantastic today, and starting values typically reach north of $100,000. Hand-built in limited numbers with a 998cc V-twin, it combined brutal speed with elegance. Collectors prize matching-numbers bikes with documented history and honest patina.

This iconic ride could top out at 125 mph, which was an astonishing feat back then. Its signature black-enameled engine gave the machine its legendary name. Additionally, the innovative design utilized the engine as a stressed member of the chassis. Finding an original model today is a dream for serious collectors.

Brough Superior

“Superior” may, in fact, be a complete understatement. Dubbed the “Rolls-Royce of motorcycles”, the Brough Superior was backed by exquisite, hand-made engineering and was favored by none other than Lawrence of Arabia himself. These days, they typically go for at least $300,000. Early SS100s were road-tested at 100 mph, and each bike was assembled to order. Surviving examples with original JAP or Matchless engines and correct fittings command premiums. Provenance matters immensely, as do period accessories and certificates, making well-documented bikes the ultimate blue-chip classics.

It is no wonder that record-breaking auction sales have seen some rare models fetch over half a million dollars. Their legendary status stems from a limited production run between 1924 and 1940. Every machine was meticulously tailored to the buyer's exact requirements, right down to the custom-shaped handlebars.

Indian Chief

The Indian Chief had its heyday during the 40s and early 50s, before the Indian Motorcycle Company was shuttered. (It later had a revival in 1999). Even then, its status as an American icon was already well established. These days, original Indian Chiefs normally go for at least $30,000. Collectors love the valanced fenders, relaxed touring stance, and torquey V-twin built for distance. Hand-shift examples with correct accessories and period colors bring premiums, and well-restored prewar or early postwar bikes often sell far higher at auction. Beyond the mechanics, the Chief boasts an undeniable charm that turns heads.

The sweeping lines of its signature sheet metal give it a beautifully streamlined profile that stands out from modern builds. Riders also praise the surprisingly smooth handling, largely thanks to the plunger rear suspension that made highway journeys a breeze.

Harley-Davidson EL “Knucklehead”

The term “knucklehead” isn’t technically official - it was retroactively applied to the EL by Harley-Davidson fans due to the bike’s uniquely shaped rocker boxes (which have since become synonymous with the brand as a whole). They normally fetch anywhere between $50,000 and $150,000 at auction. Built from 1936 to 1947, the EL introduced Harley’s landmark overhead-valve V-twin and brought genuine highway performance to American riders. Collectors crave early ‘36s, original paint, and matching-numbers drivetrains. Correct accessories and documented provenance can push pristine examples into six-figure, museum-worthy territory.

Beyond its groundbreaking engine, the EL showcased a totally fresh design that still influences modern cruisers today. The sleek teardrop gas tank and smartly integrated instrument cluster gave the vintage motorcycle a beautifully streamlined profile. It also introduced a much-needed recirculating oil system that significantly improved overall mechanical reliability.

Honda CB750 Sandcast

The term “superbike” has since been embraced by the motorcycle industry as a whole, but back in the 60s people it was still a new concept. Though some other bikes also received the title of “world’s first superbike”, the Sandcast’s prowess cannot be understated. As such, it normally goes for around $50,000, at least. Early 1969 K0 “sand-cast” bikes used rougher sand-mold cases before die-casting, making them rarer. The 736cc inline-four, front disc, and electric start reset expectations. Unrestored examples with HM300 pipes and early VINs bring serious premiums.

Riding one today is an absolute blast, taking you right back to a golden era of innovation. Its amazing reliability blew the competition away and launched the legendary Universal Japanese Motorcycle trend. Finding a survivor takes patience, but owning such monumental history is incredibly rewarding.

Ducati 750 SS

Ducati is one of the biggest names in the motorcycling world, and is synonymous with making very, very fast bikes. Only 100 750 SSs were initially made, making them some of the rarest specimens on this list. The 750 SS was made famous as the bike that won the Imola 200. They normally fetch at least $100,000. Built around a 748cc L-twin with desmodromic valves, it delivered race-bred handling and charisma. Early green-frame examples with factory documentation, original fiberglass, and correct carbs are especially coveted.

It is easy to see why fans obsess over these early models. The legendary 1974 production run featured a stunning silver fairing alongside a translucent fuel tank that let riders quickly check their gas levels. This masterpiece traces its roots directly back to Paul Smart’s iconic 1972 victory.

Norton Manx

Here’s an interesting fact about Norton: they contested every single Isle of Man TT race from 1907 all the way through to the 70s. Suffice it to say, racing - and the spirit of competition - have always been in their blood. The Manx became iconic for its featherbed frame and single-cylinder engine, and normally fetches at least $50,000. Hand-built 350cc and 500cc DOHC singles with Roadholder forks and the McCandless-designed chassis delivered uncanny stability. Bikes with documented TT history and correct magnesium parts bring premiums. It was the perfect machine for privateer racers making a name on the circuit.

That revolutionary frame completely changed how motorcycles handled corners, ensuring incredible agility. Hearing that classic engine roar today is an unforgettable experience for vintage enthusiasts. It is a true piece of motorsport history that looks fast standing still.

BMW R32

BMW shouldn’t require any introduction. Suffice it to say, they’re one of the biggest names in the automotive industry. The R32 was their very first motorcycle, and was an innovation in and of itself due to its flat-twin boxer engine and shaft drive. Expect it to be worth at least $100,000 at auction. Introduced in 1923 and designed by Max Friz, the R32 set BMW’s template for durability and balance. Collectors value original toolkits, correct carburetors, and factory finish. Provenance and unmolested mechanicals push prices higher.

It is amazing to think this machine produced just eight and a half horsepower, yet it could reach a top speed approaching sixty miles per hour. Friz drew heavily on his aviation background to build it. It also featured a brilliant wet sump oiling system. This was a huge step forward.

Triumph Bonneville T120

Though the Bonneville was never going to perform as well as some of the early “superbikes” that were coming out at the time, it became an icon in its own right and was embraced by custom and cafe racers alike. Some go for as little as $20,000 at auction, while others bring home north of $50,000. Buyers prize early pre-unit models, TT Special variants, and original two-tone paint. The 650cc parallel-twin, twin Amal carbs, and classic exhaust note define its charm, especially with verified history and sympathetic restorations.

It earned its famous name following the company's incredible top speed records at the legendary Bonneville Salt Flats in Utah. Riders quickly fell in love with its gorgeous teardrop gas tank and comfortable riding position. This beautiful machine truly captured the rebellious spirit of the swinging sixties.

Harley-Davidson XR750

Don’t be surprised to see more than a few Harley-Davidsons on this list. The XR750 was yet another incredible success for the company, and dominated flat track racing in the 70s. It was also the stunt bike of choice for none other than Evel Knievel himself. They typically go for at least $60,000 or more. Early alloy-head racers with matching cases and documented AMA history are the most coveted, especially unrestored examples. Period-correct exhausts, spares, and factory paperwork can add sizable premiums for serious collectors. Introduced in 1970 to replace the older KR model, early iron engines struggled with overheating.

However, the switch to aluminum heads in 1972 completely transformed the machine into an unstoppable powerhouse on the dirt oval. Hearing that legendary V-twin roar around a track is an experience fans absolutely live for. It is a masterpiece.

Matchless G50

Don’t let its small size fool you - the Matchless G50 has plenty of kick and power. Indeed, among the club and GP race scene in the 50s and 60s, the G50 truly was matchless - erm, unmatched. They’re worth at least $50,000 today. Collectors prize original racing trim, tidy maintenance records, and period-correct bits like rearsets and alloy tanks. Lightweight, tractable, and surprisingly durable, a well-prepped G50 still thrills at vintage events. Provenance from notable privateers or factory support can move prices well beyond guide estimates.

Introduced in 1958, this beautiful British machine boasted a 500cc single-cylinder engine that reliably churned out around fifty horsepower. It was specifically built to rival the famous Norton Manx on the track. Riders quickly loved how incredibly agile it felt through tight corners, giving them a serious competitive edge.

MV Agusta 750 S

The 750 S is another rare machine, this time manufactured by MV Agusta. Though it was intended to replace the 600, only some 500 units of the 750 S were made, which makes sense when you consider that they were put together by hand. They’re worth at least $80,000. Hand-assembled inline-four charisma, signature red-and-silver livery, and that unmistakable Italian craftsmanship make it a blue-chip prize. Collectors chase matching-numbers examples with factory paperwork and original exhausts. Low-mileage survivors or expert restorations from known specialists regularly soar well above guide prices.

The beautiful sculpted fuel tank and dramatic four-into-four exhaust system gave this motorcycle an aggressive, unforgettable profile. Riders loved hearing that gorgeous 743cc engine rev out on the open road. Interestingly, designers equipped it with a shaft drive, which was an unusual choice for the era.

Ariel Square Four

Take a guess as to where the Square Four got its name. Indeed, designed by the legendary Edward Turner, the Ariel Square Four became iconic due to its unique square four-cylinder layout and the fact that it performed beautifully, even for a pre-war machine. They can fetch as much as $70,000 at auction nowadays, if not more. Later Mk II models adopted alloy heads, improved cooling, and smoother manners. Collectors value original silencers, correct panels, and paperwork. Well-sorted riders remain surprisingly usable. It is fascinating to realize this classic stayed in production from 1931 until 1959.

The engine evolved over those decades, eventually growing into a robust 1000cc powerhouse. Enthusiasts adore how smooth the power delivery feels on the open highway. The signature four-pipe exhaust system gave later editions an unmistakable presence. Finding one today is quite an accomplishment.

BSA Gold Star

Another exquisitely crafted, hand-built machine, the BSA Gold Star does, indeed, receive a gold star for its meticulous engineering alone. Each bike came with a documented dynamometer results sheet, allowing owners to see how much horsepower could be produced. Suffice it to say, they were impressed, and the Gold Star is normally worth at least $50,000. Collectors favor DB34 Clubman-spec machines with original alloy barrels, Amal GP carbs, and clip-ons. Proven race history, factory records, and correct toolkits push pristine examples well beyond typical guide prices.

Produced until the early 1960s, this British legend absolutely dominated the club racing scene. Enthusiasts love the iconic 500cc single-cylinder engine that delivers a thrilling ride. Its incredible handling made it a massive favorite among privateer racers seeking a competitive edge. Owning one connects you to a golden age.

Velocette Thruxton

The Velocette Thruxton - sometimes just called the Thruxton, sometimes the Venom Thruxton - is an iconic British cafe racer, whose production was cut short by the closing of the company behind it. They’re typically worth at least $70,000. Based on the Venom, its tuned 499cc single with big-fin head and Amal GP carb delivered serious clubman pace. Clip-ons, rearsets, and close-ratio gears made it a favorite at Thruxton and cafe haunts. Matching-numbers bikes with original fiberglass tanks and paperwork command firm premiums. It achieved legendary status by winning the 1967 Isle of Man Production TT race.

Reddit / daydreamdisasters
Only about eleven hundred machines were manufactured before the factory closed its doors in 1971. Due to that short run, spotting a survivor today feels like finding hidden treasure. Riders absolutely love the distinct exhaust sound and how smoothly it handles.

Harley-Davidson JD

Though they’d been around since 1903, the story of Harley-Davidson as we know it pretty much began here with the JD, which introduced the now iconic teardrop-shaped engine. They’re pretty rare, and as such, typically fetch at least $100,000. Built in the late 1920s, these big-twin tourers showcased handsome nickel-plated fittings, rigid frames, and graceful tanks that set Harley’s silhouette for decades. Collectors pay premiums for matching-numbers examples, original paint, and complete accessories. Documented history and sympathetic mechanical rebuilds can push concours-quality bikes well into six figures.

The massive 74-cubic-inch V-twin motor gave riders serious power for the era. Getting one out on the highway gives you a real feel for early motorcycling, back when manual hand shifters were standard. It is easy to see why police departments eagerly adopted them as reliable pursuit vehicles.

Zundapp KS 601

The Zundap KS 601 is probably one of the least recognized motorcycles on our list. Don’t be mistaken, though - they still fetch a handsome sum at auction (at least $50,000), with “Green Elephant” sidecar setups (think Indiana Jones and the Last Crusade) being particularly sought after. Powered by a 597cc flat-twin and shaft drive, the KS 601 built a reputation for rugged touring. Matching-numbers rigs, original paint, and documented Elefantentreffen or military history add value. Correct Bosch electrics and period accessories push prices upward. Manufactured in Germany during the nineteen fifties, this machine was beautifully engineered by Ernst Schmidt.

Fans quickly fell in love with its tough tubular frame and incredibly smooth suspension. Because it weighed quite a bit, riders appreciated its serious pulling power. Owning one today means you hold a wonderful piece of postwar history.

Royal Enfield Interceptor 750

The Interceptor name recently made a comeback in 2018, but it first found success way back in the late 60s and early 70s before it was discontinued. The 750 Interceptor was one of the fastest racers in production, and is much rarer than many Norton and Triumph models. It fetches at least $30,000 today. Collectors look for Series II bikes with strengthened cases, twin Amal carbs, and original chrome tank panels. Low-production, U.S.-market survivors with matching numbers and paperwork bring premiums.

Enthusiasts also praise the Series II for its wet-sump crankcase design and dynamically balanced crankshaft, which made it incredibly smooth on the open road. Pushing out fifty-two horsepower from its 736cc engine, it could easily top out over 115 mph. Interestingly, these later models were manufactured in an underground factory in Wiltshire, England.

Excelsior Super X

The Excelsior Super X may not be the most well-known model on this list, but its arrival onto the scene was impactful as it was one of the first V-twins to challenge Harley and Indian’s domination. They typically fetch over $100,000. Introduced in the mid-1920s, the 45-cubic-inch twin delivered surprising speed and durability, helping ignite America’s performance street scene. Surviving machines are scarce because production ended early after Schwinn shuttered the brand. Matching-numbers bikes with original paint, correct Schebler carburetors, and documented provenance command serious premiums.

Designed by brilliant engineer Arthur Constantine, this machine essentially created the famous forty-five cubic inch class. This bold move forced rival companies to quickly scramble and launch their own competing models. Riders really loved the innovative unit construction block, which neatly housed the motor and transmission inside a single durable casing.

Crocker Big Twin

Nicknamed “Big Twin”, this powerful twin-cylinder machine from Crocker was probably the fastest motorcycle of the pre-war era. It’s also an exceedingly rare bit of engineering and is worth over $300,000. Hand-built in Los Angeles by Al Crocker, each was effectively a bespoke hot rod, tuned for the buyer and famous for out-running contemporary Harleys and Indians. With production numbers tiny and many lost to hard use, survivors are coveted. Matching-numbers engines, documented history, original parts, and correct finishes can rocket exemplary examples far beyond guide prices.

Al Crocker famously offered a full refund to any rider whose bike was beaten by a stock Harley or Indian. These incredible machines featured cast aluminum gas tanks that withstood intense vibrations. Spotting a genuine survivor today is the ultimate dream for vintage collectors, representing the pinnacle of early American muscle.

Sunbeam Model 9

Though it’s another “sleeper hit”, the Sunbeam Model 9 quickly established itself as both a reliable and powerful sports tourer in the 20s and 30s. Backed by British craftsmanship and elegant styling, they fetch anywhere between $30,000 and $50,000. Collectors prize well-sorted 493cc OHV singles with girder forks and classic black-and-gold tanks. Original paint, matching numbers, and tidy paperwork lift values. As do Model 90-style upgrades. Smooth, torquey manners make them usable at vintage rallies, and correct period accessories or known provenance can push top examples higher.

Often referred to as the gentleman’s motorcycle, it boasted an incredibly high standard of finish that rival companies struggled to match. Enthusiasts absolutely love the iconic gold leaf pin-striping that stands out beautifully against the deep black enamel. Riding one today offers a surprisingly comfortable experience on country roads.

Indian Four

Originally built in 1928, the Indian Four was discontinued before the war and never returned to the roads. That’s a shame, because it’s probably one of the finest-looking motorcycles on this list with its art deco stylings. They typically go for at least $100,000. Powered by a silky inline-four, it delivered refined touring manners and a distinctive exhaust note. Ace Four roots add cachet, while correct trim and matching numbers matter to collectors. Documented history and careful restorations can send top examples comfortably into six-figure territory. Enthusiasts absolutely love the iconic skirted fenders introduced on the 1940 models, giving the machine a beautifully streamlined look.

Yamaha TZ750

Despite being one of the biggest names in motorcycling (and also guitar-ing, for some reason), we haven’t seen any Yamahas yet. That changes with the TZ750, one of the most legendary racing motorcycles in history. They’re typically worth at least $75,000. Race-bred and ferociously fast, the 747cc two-stroke four delivered outrageous power and wheelspin, defining an era. Kenny Roberts famously tamed it at Daytona, cementing the bike’s legend. Surviving factory and privateer machines with documented provenance, original exhausts, and spares command premiums, especially unrestored examples or meticulous period-correct restorations.

Introduced in 1974, this incredibly dominant machine quickly earned the intimidating nickname “Godzilla.” It absolutely owned the famous Daytona 200, taking nine consecutive victories. Weighing just under 340 pounds, it could hit a blazing top speed of almost 180 mph on long straightaways. It is an amazing ride.

Moto Guzzi V8 “Otto Cilindri”

Ranked as one of the greatest motorcycles of all time by none other than the Discovery Channel, the Moto Guzzi V8 (or “Otto”) was also one of the most ambitious Grand Prix bikes of all time. As a museum-worthy bit of engineering, they ain’t exactly cheap, and will set you back around $300,000. Its 500cc eight-cylinder engine with tiny pistons made it a technological moonshot. It was blisteringly fast, but fiendishly complex. Surviving examples and factory replicas are scarce; documented history, original spares, and race provenance push values higher. Designed by engineer Giulio Carcano, this Italian marvel packed incredible power.

The liquid-cooled motor delivered 78 horsepower, pushing the lightweight machine to an astonishing top speed of over 170 mph. Because early suspension technology struggled to handle such raw performance, it became famously difficult to tame.

Laverda SFC 750

Though they aren’t around anymore, Laverda was known for its innovation and immaculate Italian style. The SFC 750 is considered to be a work of art, and its orange bodywork is iconic. It easily fetches some $100,000 at auction. Hand-built for endurance racing, the SFC—Super Freni Competizione—packed a tuned 744cc parallel twin, close-ratio gearbox, and lightweight fiberglass fairing. Collectors prize early 1971–72 drum-brake bikes and later twin-disc models, especially with matching numbers, factory paperwork, and original orange panels. Properly sorted examples remain thrilling, reliable, and collectible.

With only 549 units officially manufactured throughout their run, locating one today feels incredibly special. These Italian masterpieces famously dominated European endurance events throughout the early seventies, securing multiple legendary victories. Every machine was meticulously dyno-tested prior to leaving the factory, guaranteeing top-tier performance. Owning such magnificent history is highly rewarding.

Suzuki RG500 Gamma

Though its production only lasted two years, the RG500 Gamma quickly established itself as a force to be reckoned with. A road-legal version of the powerful GP two-stroke, it goes for at least $50,000. Powered by a raucous 498cc square-four with twin cranks, it delivered a razor-sharp, peaky rush and minimal weight in a box-section frame. Collectors covet unmolested survivors with original bodywork and exhausts. Limited imports, low mileage, and documented history push values higher, especially for bikes with factory spares and paperwork. Riding this remarkable machine feels like stepping onto a starting grid.

The thrilling engine produces roughly ninety-five horsepower, coming alive once revs climb past six thousand. Tipping the scales at an incredibly light three hundred forty pounds, the handling is amazingly agile. It brings genuine championship-winning motorsport magic to public roads.

Kawasaki Z1 900

Introduced way back in 1972, the Z1 (and later Z1 900) was Japan’s very first liter-class superbike, and was designed to compete with the legendary Honda CB750. These days, it’s worth at least $40,000. Powered by a 903cc DOHC inline-four with a front disc and four Mikuni carbs, it mixed reliability with genuine 130-mph pace.

Developed under the fun code name "New York Steak," Kawasaki delayed the launch to build a bigger, more powerful engine. This bold move paid off. In 1972, the machine set an impressive twenty four hour endurance record at Daytona, proving its durability. Fans still love its signature ducktail rear bodywork.

Harley-Davidson WLA

As a proud American brand, it makes complete sense that Harley-Davidson would ingratiate itself with the military. The WLA was the result of this partnership, and is nowadays something of a WWII relic, worth at least $40,000. Built in vast numbers with a rugged 45-cubic-inch flathead V-twin, it wore olive-drab paint, blackout lights, and heavy-duty racks. Many went overseas via Lend-Lease, while Canadian WLC variants added unique fittings. Collectors prize matching-numbers examples with leg shields, rifle scabbards, tool rolls, and paperwork; untouched survivors command healthy premiums.

Nicknamed the "Liberator," this iconic machine saw nearly ninety thousand units produced during the war. It became famous for its incredible reliability across rough terrain. Interestingly, all models built after Pearl Harbor were stamped with a “42WLA” prefix, regardless of their manufacturing year. Finding a preserved survivor today is thrilling.

Triumph TR6 Trophy

Introduced as a replacement for the popular Tiger model, the TR6 Trophy was highly favored by the legendary Steve McQueen and won even more acclaim during its competition years. These days, it’s worth some $50,000 or so. Based on the 650cc parallel-twin, the TR6 blended tractable torque with light, precise handling that made it a desert-sled favorite. High pipes, quick-change wheels, and simple, rugged construction endeared it to privateers. Collectors chase matching-numbers bikes with documented ISDT or off-road provenance, original paint, and correct scrambler trim.

Produced until the early seventies, this British machine proved incredibly versatile. Fans still absolutely adore its distinctive exhaust note today.

Rudge Ulster

One of the oldest models on this list, the Rudge Ulster is also one of the least known, as production ended at the outbreak of WWII. It had a racing pedigree and advanced engineering for its time, and is worth at least $50,000. Collectors prize well-sorted 500cc singles with four-valve heads, girder forks, and tidy period details. Matching numbers, original paint, and documented competition history drive premiums. Smooth, tractable performance and elegant lines keep demand strong, and properly restored examples remain engaging, reliable riders at vintage events.

Ducati 900 SS

The 900 SS was a follow-up to the legendary 750 SS, exceeding that famous bike’s own legendary prowess and performance. It typically fetches around $40,000 at auction. Built around a 864cc bevel-drive L-twin with desmodromic valves, the 900 SS delivered razor-sharp handling, strong midrange, and unmistakable Italian charisma. Early round-case examples and authentic “green frame” styling cues are especially prized. Matching-numbers engines, original Conti silencers, and factory paperwork raise values. Clean, unrestored survivors or expert restorations from known specialists routinely outperform price guides at major auctions.

Early mass-produced versions featured a beautiful fiberglass tank with a translucent stripe that allowed riders to easily check fuel levels. Though difficult to manufacture, this motorcycle essentially saved the beloved company from extinction.

Montesa Cota

An offshoot of Honda, Montesa was responsible for this Spanish-made trials bike. It’s a rare model that you don’t see spoken about often, and fetches a modestly handsome sum of around $20,000. Collectors favor early Cota 247 and 348 two-strokes with original tank/seat units, alloy rims, and tidy controls. Light, tractable power and featherweight frames make them perfect for observed trials and vintage events. Period documentation, matching numbers, and uncracked fiberglass boost value, while sympathetic mechanical refreshes keep these agile mountain-goats reliable without hurting authenticity.

Introduced in 1968, the Cota 247 helped establish the brand's dominance in international competitions. Its innovative one-piece fiberglass tank and seat design even won a prestigious industrial design award. Enthusiasts adore how the torquey engine allows for incredibly smooth maneuvering over rough terrain. Spotting one today is a thrill.

Bimota DB1

The DB1 is responsible for saving Bimota from certain doom. It’s an exotic, Ducati-based motorcycle with style to match and racing pedigree. They were only made in a limited number and, as such, normally fetch around $50,000. Hand-built in Rimini around Ducati’s desmo 750 L-twin, it featured a compact chrome-moly space frame, fully enclosed bodywork, and razor-sharp geometry. DB1S and DB1SR variants upped the spec for homologation. Collectors chase original fairings, undrilled rotors, and factory paperwork; low-mileage, matching-numbers bikes command strong premiums. Designed by Federico Martini, this Italian masterpiece debuted in 1985 and became highly celebrated.

Its fully covered fiberglass bodywork famously sparked an aerodynamic design trend adopted by numerous other manufacturers. Weighing a remarkably light 354 pounds, the DB1 provided riders with acrobatic handling and fierce acceleration. Finding a pristine survivor today is incredibly rewarding.

Honda NR750

Ending our list with the most recent motorcycle, the Honda NR750 is already legendary despite its relatively young age. Its exotic engineering and oval pistons have made this one worth at least $100,000. Built in very limited numbers in the early ’90s, the street-going NR wrapped its oval-piston V4 and 32 valves in exquisite bodywork and a single-sided Pro-Arm swingarm. Fit and finish bordered on jewelry, and many were cosseted as collectibles. Low-mileage, unmodified examples with factory accessories and paperwork command the strongest premiums.
