Born in 1973, the HB1 had a SOHC heart taken from a Honda CB750. Unfortunately, only ten units from this bike were ever produced.

Only a few, maybe 10 of the HB1 were built. None of them was designed to be street legal, they were all meant to be race bikes. The most famous Final Driver was Luigi Anelli, who raced a HB1 in 1973. Today, this is probably the most sought after special framed Honda CB 750 SOHC/4 bike. Ceriani front fork, Marzocchi rear dampers, Fontana brakes - Bimota used only the best accessories.
