Three years ago, Ritmo Sereno of Tokyo produced a stunning orange BMW R80 track 
bike—the highly successful ‘Nakajima’ racer. Now a Ritmo customer has commissioned
a road-going version—and this is it. It’s based on a 1991 R100 RS, but many of the
other details are close to the track machine.

The suspension is Öhlins front and back, the brake system is from Brembo and carburetion
is Keihin FCR. Ritmo has paid a lot of attention to weight, so the 230kg-or-so of
the stock machine has been reduced to a gossamer 175kg. (The battery holder, oil
catch tank and the frame from the engine backWards are handmade in lightweight aluminium
alloy.) Power is now around 80bhp at the back wheel, helped by a custom-made 2-into-
1 exhaust system routed through a modified center stand.
