Bimota BB1 Supermono

With Phil Aynsley

The BB1 Supermono was Bimota’s only single cylinder motorcycle. First displayed at the Cologne Show in 1994, production began the following year with 524 made, including 140 of the Biposto version (with pillion seat and painted dark blue in production from 1996).

The BB1 used the same Rotax 650cc four-stroke motor that was used by BMW for their F650. The twin carburettor motor made 48 hp at 6500 rpm and gave the 145 kg machine a top speed of 177 km/h.

Fuel tank in the bellypan!

A single front disc was standard but a second was an option. One interesting design feature was the placement of the fuel tank under the motor for a lower centre of gravity.
