Three Men, One Name: The Birth of Bimota
In Rimini, on Italy's Adriatic coast, three friends were manufacturing heating and air conditioning equipment in the 1960s. Nothing destined them to become motorcycle legends. Yet, the name of their company already hinted at their destiny: Bimota is formed from the first two letters of each of their surnames — BIanchi (Valerio), MOrri (Giuseppe) and TAmburini (Massimo). An acronym that has become one of the most prestigious names in motorcycling history.
The shift to motorcycles came from an accident. While racing at the Misano circuit, Massimo Tamburini crashed heavily and broke three ribs. Convinced that his Honda CB750 Four suffered less from its engine than from its overly soft chassis, he decided to build an entirely new frame for it. This first chassis, named HB1 (Honda-Bimota 1), marked the official birth of the manufacturer in 1973. A philosophy was born: buy the engine; sublimate the chassis.
The Bimota Concept: A Production Engine, an Exceptional Chassis
Here's the recipe that made the brand unique: take a mass-produced engine, most often Japanese and proven, then dress it with a bespoke chassis designed for pure performance. Chrome-molybdenum steel trellis frames, then aluminum ones, millimeter-precise geometries, extreme weight reduction, high-end brakes and suspensions: each Bimota is a piece of mechanical goldsmithery produced in confidential quantities.
The nomenclature itself tells this story. The first letter indicates the origin of the engine, the second the brand name: K for Kawasaki, S for Suzuki, Y for Yamaha, D for Ducati, H for Honda. This approach makes Bimota a spiritual cousin of other chassis-obsessed craftsmen, like the American Erik Buell, who grafted his own frames onto Harley-Davidson V-twins. With one difference: with Bimota, exclusivity and price reach stratospheric heights.

KB1, DB1, SB6, YB: The Models That Became Legends
The first great commercial success was the KB1. Launched in 1978 around the Kawasaki Z1000 four-cylinder engine, it sold over 800 units — a huge number for such a artisanal manufacturer. It established Bimota as the maker of ultimate superbikes, at a time when the Kawasaki 900 Z1 reigned supreme in the world of large displacement bikes.
In 1985 came the DB1, the first Bimota with a Ducati engine (the 750 cm³ Pantah twin). Designed by the new chief engineer Federico Martini — who had replaced Tamburini, who went to Cagiva — its fully faired line was an aesthetic revolution. More importantly, its approximately 500 units sold financially saved the company and sealed a lasting alliance with Ducati. On the Yamaha side, the YB series also shone in competition: the YB4, powered by the FZ750 engine, earned Bimota a Formula TT World Championship title in 1987 with Virginio Ferrari.
But the commercial masterpiece remains the SB6 from 1994. Powered by the 1,074 cm³ four-cylinder engine of the Suzuki GSX-R 1100, designed by engineer Pierluigi Marconi, it became the best-selling Bimota in history with 1,144 units. A pinnacle of pure sportiness, carved in aluminum and sold at the price of a small luxury car.
The Tesi: The Motorcycle That Reinvented Steering
No Bimota better embodies the brand's technical audacity than the Tesi. Its name literally means "thesis" in Italian: it was born in 1982 from Pierluigi Marconi's final university project at the University of Bologna. His revolutionary idea? To abandon the traditional telescopic fork in favor of hub-center steering, where the front wheel is guided by a swingarm and not by sliding tubes.
The theoretical advantage is immense: by separating the function of braking from that of steering, the Tesi eliminates front dive during braking and gains stability. Presented as a prototype as early as 1983, it only reached the road in 1990 with the Tesi 1D, powered by a 904 cm³ Ducati twin-cylinder engine derived from the 851. Complex and expensive, the Tesi was never a mass success, but it became a cult icon, evolving to this day — the modern Tesi H2, born from the partnership with Kawasaki, now combines this unique chassis with a 998 cm³ supercharged four-cylinder engine developing approximately 228 horsepower.
Tamburini, the 916, and the Exotic Legacy
It's impossible to talk about Bimota without mentioning the destiny of its "T". Massimo Tamburini (1943-2014) left the company around 1985, after eleven years, to join the Cagiva group. It was there that he would create his absolute masterpiece: the Ducati 916 of 1994, a sportbike whose beauty redefined the very idea of a superbike. He then designed the sublime MV Agusta F4, offering the Cascina Costa brand a triumphant rebirth.
The man dubbed the "Michelangelo of motorcycle design" thus laid the foundations of his genius in Rimini, in the Bimota workshops. The lineage is direct: the cult of the perfect chassis, the obsession with lines, the refusal of compromise. Bimota thus remains the spiritual ancestor of a whole segment of Italian exoticism, alongside passionate sportbikes like the Aprilia RSV Mille.

Financial Rollercoaster and Rebirth
Bimota's history is also a long series of financial crises. Manufacturing exceptional motorcycles in tiny quantities is expensive, very expensive, and the balance is always precarious. The final blow came with the V-Due in 1997: a sportbike equipped with a 500 cm³ two-stroke engine with direct injection, designed and manufactured entirely in-house — a first for the brand. Alas, this unprecedented engine proved capricious and riddled with development flaws.
The massive recall and re-engineering costs swallowed up cash flow. With only 361 units produced and the loss of racing partners, Bimota collapsed and filed for bankruptcy in the early 2000s. Several takeover attempts followed, until the decisive turning point in October 2019: Kawasaki Heavy Industries acquired a stake of approximately 49.9%. Backed by the industrial power of the Japanese giant, the Rimini brand was reborn once again, true to its eternal motto: the best engine, in the best chassis.

FAQ — Frequently Asked Questions
Where does the name Bimota come from?
It is formed from the first two letters of the names of the three founders: BIanchi, MOrri, and TAmburini. The brand was founded in 1973 in Rimini, Italy.
Does Bimota manufacture its own engines?
No, historically Bimota purchases mass-produced engines (often Japanese: Kawasaki, Suzuki, Yamaha, or Italian Ducati) and integrates them into ultra-exclusive in-house chassis and cycle parts. The only exception was the 1997 V-Due, whose two-stroke engine was developed in-house — a commercial failure.
What is the connection between Bimota and the Ducati 916?
Massimo Tamburini, the "T" in Bimota, left the company around 1985 to join the Cagiva group, where he designed the Ducati 916 in 1994, and then the MV Agusta F4. He had honed his chassis genius at Bimota.
What is the Bimota Tesi?
It is a revolutionary motorcycle featuring hub-center steering instead of a telescopic fork. Born from a university thesis in 1982 and commercialized in 1990, it remains a technical icon, with variations produced up to the modern Tesi H2.
Does Bimota still exist today?
Yes. After several bankruptcies, notably after the failure of the V-Due, the brand was relaunched thanks to Kawasaki Heavy Industries acquiring approximately 49.9% of its capital in October 2019.
