The BB1 ​​is a model of the Italian motorcycle manufacturer Bimota.

The BB1 ​​Supermono was unveiled at the motorcycle show in Cologne 1994.

The engine is a single cylinder four-stroke 650 cc Rotax from the Austrian manufacturer. This engine in particular is used for the BMW F650 range, hence the model name: Bimota BMW No. 1.

It delivers 48 hp at 6500 rpm and 9 kgf-m at 6000 rpm, coupled to a five-speed gearbox. It is powered by two
Mikuni 33 mm diameter carburettors.

The frame is a tubular aluminium mesh and the swing arm is also made of aluminium tube.

Suspension consists of a 43 mm diameter telescopic fork and a single shock from Paioli. The latter is adjustable preload and rebound.

Braking is entrusted Brembo, a 320 mm floating disc in front and 230 mm disc fixed to the rear, respectively pinched by four clamps and two pistons. A second front brake disc was optional.

The rims are three spokes Antera aluminium. Mufflers are fully included in the saddle shell.

Mudguards and the dressing of the instrument panel are made of carbon fiber.

The fuel tank is not typically placed above the engine, but below the engine guard. This arrangement results in a low center of gravity.

The first prototype was presented using a single rectangular headlight, but two round lenses were finally chosen for the production bike.

Bimota also produced a set of parts, for €10,000 more, to prepare the bike for competition. This kit includes a complete lining, magnesium wheels, an electronic fuel injection system and new suspension.

The BB1 ​​has been engaged in the Italian championship in 1994. Displacement was increased to 725 cc, with a power delivery 75 hp at 10,000 rpm.

Supermono Biposto

The Cologne Fair 1995 sees the presentation of the BB1 ​​Supermono Biposto.

The general characteristics do not change but it can now carry a passenger. The rear frame was adapted to be able to carry the excess weight. Mufflers are still in a high position in the saddle, but now visible.

The BB1 ​​Supermono was only available in red and grey while Biposto was sold in dark blue. Both have inscriptions in the fairing "Bimota" and "Powered by BMW."

The prototype unveiled at Cologne in 1994 had a red fairing, with white and yellow zig zag. The lower part of the fairing sported the Italian and German flags. The first model was red and gray, but the Bimota logo was replaced by the words "SM Super Mono".

In total, 524 BB1's were produced, of which 376 and 148 were Supermono and Supermono Biposto respectively. They were sold €8,780 € 11,026 respectively.
