Bimota HB1

In September 1972, Massimo Tamburini crashed his Honda 750 Four at the Misano racetrack. The accident left him with three broken ribs. If the accident hadn’t occurred, Bimota may never have come into existence. While Massimo was recuperating, he constructed a tubular steel frame that could withstand the horsepower being produced by the big Japanese manufacturer’s engines. The frame Massimo constructed lowered the center of gravity and reduced the weight of the original Honda. With the creation of the HB1, the Bimota was born. Only ten of these bikes were ever produced.

The Bimota name was derived from its founder’s initials; Bianchi, Morri and Tamburini. However, it was the enthusiasm and engineering excellence of Massimo Tamburini that carried the Company to success. In the 1970s, Bimota produced racing frames that caught the attention of serious bike racers. Frames such as the YB1, YB2, YB3 and HDB1, HDB2 and SB1, were of superior quality and the perception of what a racing bike should be was changed forever.

Only 10 of the HB1 were built. None of them was designed to be street legal, they were all meant to be race bikes. The mos it beginst famous 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.

………..now it begins.
