12 Rarest Motorcycles in the World and What They're Worth

Only four 1949 AJS E90 Porcupines were ever assembled. One sold at Bonhams in 2012 for $750,000. Meanwhile, a single 1915 Cyclone Board Track Racer changed hands at Mecum Auctions for $852,000 in 2015. These are not bikes you spot at a weekend rally. Most riders will go their entire lives without seeing a single one in person.

This guide covers 12 of the rarest motorcycles ever built, each with verified production numbers, real auction prices, and the specific engineering or history that makes it collectible. Whether you follow vintage racing, American V-twins, or postwar British singles, this is the list that separates genuine rarities from bikes that are simply old.

What Makes a Motorcycle One of the Rarest in the World?

A motorcycle becomes rare through a combination of three factors: low production numbers, high attrition, and historical importance. A bike that was made in a run of 50 units and raced in a world championship will always be worth more than one produced in the thousands and stored in a shed. The collector market distinguishes between "uncommon" (under 5,000 made), "scarce" (under 500), and "genuinely rare" (under 100). Every bike on this list falls into that last category, or close to it.

Survival rate matters as much as production count. Harley-Davidson built over 3,000 of its 1936 EL "Knucklehead" in the first year alone. But because riders actually rode them hard for decades, original-condition survivors are extremely scarce. Contrast that with the Ecosse ES1 Spirit: all 10 units were sold to collectors and preserved from day one. Low production plus low survival equals genuine rarity. Racing motorcycles have especially low survival rates because crashes, mechanical failures, and the constant search for speed destroyed most of them before anyone thought to save them.

Provenance adds another layer. A Brough Superior SS100 that T.E. Lawrence owned is worth more than an identical SS100 without that history. Documentation, racing results, and famous ownership all push a motorcycle from "uncommon" into "irreplaceable." The rarest motorcycles on this list combine all three: tiny numbers, few survivors, and a story worth telling.

The 12 Rarest Motorcycles Ever Built

1. 1949 AJS E90 Porcupine

Only 4 built. Associated British Motorcycles designed the E90 Porcupine specifically for the 1949 FIM 500cc World Championship, and Les Graham won the inaugural title on one. The engine was a supercharged parallel twin with unique "porcupine" cylinder-head spikes for cooling. One sold at Bonhams in 2012 for approximately $750,000. Fewer than 4 are confirmed to survive, making it one of the rarest motorcycles in the world by any measure.

2. 1915 Cyclone Board Track Racer

Approximately 12 survive from an unknown but small original production run. The Cyclone used a 45-degree overhead-cam V-twin that produced around 45 hp, which was remarkable for 1915. Board track racers were ridden at speeds exceeding 100 mph on wooden velodrome tracks with no brakes. A restored example sold at Mecum Auctions in 2015 for $852,000. Most surviving units are in private collections or museums like the Barber Vintage Motorsports Museum in Birmingham, Alabama.

3. Brough Superior SS100

About 383 built between 1924 and 1940 at the Brough factory in Nottingham, England. George Brough hand-assembled each bike and guaranteed a top speed of 100 mph, which was extraordinary in the 1920s. T.E. Lawrence (Lawrence of Arabia) owned seven Brough Superiors and called them "the Rolls-Royce of motorcycles." One of Lawrence's bikes sold at Bonhams in 2018 for over $480,000. Fewer than 200 are believed to survive. If you are interested in classic riding style, the vintage-inspired helmets collection carries that same era of design.

4. Vincent Black Lightning

Only 31 produced between 1948 and 1952 at the Vincent factory in Stevenage, England. The Black Lightning was the racing variant of the Black Shadow, stripped to 380 pounds with a 998cc V-twin making around 70 hp. Rollie Free set a 150.313 mph land-speed record on one at Bonneville in 1948, famously lying flat on the bike in nothing but a bathing suit to reduce drag. A 1951 model sold at Bonhams in Las Vegas in 2018 for $929,000, setting a world record for a motorcycle at auction at the time. Philip Vincent originally envisioned mass production, but postwar material costs killed those plans.

5. Crocker V-Twin

Approximately 72 built between 1936 and 1942 in Los Angeles by Albert Crocker. Each engine was hand-cast and individually machined. The Crocker V-twin produced roughly 50 hp and could outrun any Harley-Davidson or Indian of its era. Crocker stopped production when World War II redirected materials. Original examples now sell for $300,000 to $400,000 at auction. Fewer than 50 are confirmed to exist.

6. Dodge Tomahawk

Only 9 produced, plus the original concept. Dodge built the Tomahawk around a 500-hp, 8.3-liter V10 engine from the Dodge Viper. It had four wheels arranged in two closely spaced pairs, technically making it something between a motorcycle and a car. It was never street-legal and was sold as a "rolling sculpture" at Neiman Marcus for $555,000 per unit. Top speed was theoretically over 300 mph, though it was never independently verified. All 9 production units sold out. It remains one of the strangest and rarest motorcycles ever offered for public sale.

7. Ecosse ES1 Spirit

Only 10 built. The Scottish manufacturer Ecosse Moto Works priced the ES1 at $3.6 million, making it one of the most expensive production motorcycles in history. It used a billet-aluminum frame, carbon-fiber bodywork, and a 2,150cc engine producing 200 hp. Each unit was custom-configured for the buyer. The company ceased operations after completing the run. Every ES1 went to a private collector.

8. MTT Turbine Superbike Y2K

Around 5 original Y2K models were built by Marine Turbine Technologies in Franklin, Louisiana. The Y2K used a Rolls-Royce Allison 250-C18 turboshaft engine, the same type used in Bell 206 helicopters. Output was approximately 320 hp with exhaust temperatures exceeding 1,400 degrees Fahrenheit. Jay Leno famously owns one. MSRP was $175,000 to $200,000 when new, and surviving units rarely appear for sale.

9. 1907 Harley-Davidson "Strap Tank"

Harley-Davidson built its earliest motorcycles in a 10-by-15-foot shed in Milwaukee. The 1907 "Strap Tank" gets its name from the leather straps that held the fuel tank to the frame. Total production for 1907 was roughly 150 units across all models. Fewer than 5 strap-tank models are confirmed to survive. One sold at a Mecum auction for over $1 million. These are museum-grade machines. If you appreciate heritage biker style, our biker boots guide covers gear with that same built-to-last DNA.

10. Confederate Wraith B210

Limited to 10 units. Confederate Motorcycles (now Curtiss Motorcycles) built the Wraith in Birmingham, Alabama, with a 2,163cc V-twin producing 200 hp in a carbon-fiber and titanium frame. Each bike weighed 410 pounds dry. Price was $112,000. Confederate intentionally kept production low to maintain exclusivity. The company has since pivoted to electric motorcycles under the Curtiss brand.

11. MV Agusta F4 CC

Exactly 100 produced. Named after Claudio Castiglioni, who revived MV Agusta, the F4 CC featured a 1,078cc inline-four making 200 hp. Each unit was personally inspected by Castiglioni before delivery. MSRP was $120,000. The F4 CC is the most "accessible" bike on this list in terms of production numbers, but its collector value keeps climbing because MV Agusta purists consider it the peak of the F4 platform.

12. Hildebrand and Wolfmuller (1894)

The Hildebrand and Wolfmuller is considered the first production motorcycle in history. Roughly 800 to 2,000 units were built between 1894 and 1897 in Munich. The 1,489cc twin-cylinder engine produced 2.5 hp and used rubber belts connected directly from the pistons to the rear wheel. Top speed was about 28 mph. Very few survive intact, and most are in European museums like the Deutsches Museum in Munich. Authenticated examples have sold for over $100,000. Owning one means holding a piece of the origin story of motorcycling itself.

5 Mistakes Collectors Make When Chasing Rare Motorcycles

1. Confusing "old" with "rare." A 1975 Honda CB750 is old, but Honda built over 400,000 of them between 1969 and 1978. Age does not equal rarity. Production numbers and survival rates determine actual scarcity. Always check how many were built and how many are known to exist before assuming a vintage bike is collectible.

2. Skipping provenance verification. Rare motorcycles attract fakes. Forged VIN plates, re-stamped engine cases, and fabricated documentation are real problems in the collector market. A Crocker V-Twin without matching engine and frame numbers, a verifiable chain of ownership, or period-correct components loses most of its value. Use resources like the Antique Motorcycle Club of America for authentication.

3. Buying on hype without checking recent auction data. Asking prices on dealer websites and actual hammer prices at Bonhams, Mecum, or RM Sotheby's are often very different. A seller might list a Brough Superior SS100 at $600,000, but the last verified auction result was $480,000. Always reference completed sales, not listings.

4. Ignoring storage and maintenance costs. A $300,000 Crocker V-Twin needs climate-controlled storage, specialized insurance (typically 1 to 2 percent of appraised value per year), and a mechanic who understands pre-war American V-twins. Budget $5,000 to $15,000 per year in carrying costs for a six-figure collector bike.

5. Restoring when you should preserve. Over-restoration destroys value. A Vincent Black Lightning with original paint, patina, and wear marks is worth more than one stripped and repainted to showroom condition. The collector market increasingly rewards "preservation class" bikes with documented original finishes over frame-off restorations. If you are looking for riding gear that ages well rather than falling apart, our most expensive motorcycles guide covers the same philosophy of quality over quantity.

The rarest motorcycles on this list are not just expensive. They represent specific moments in engineering, racing, and design that can never be repeated. Whether your budget is $100,000 or $1 million, the same rules apply: verify everything, buy the best example you can afford, and ride the gear that matches your passion. If you want biker gear built with that same "made to last" mindset, the rider gear collection is a good place to start.
