History of the Bimota HB4
The HB4 marked Bimota’s return to motorcycle racing in 2010, when the company supplied machines to teams in the new Moto2 class. As required by the class rules, the bike used a Honda engine derived from the CBR600RR, in a chassis designed by Bimota.

In the first season the best result for an HB4 rider was fourth place in the Dutch TT, taken by the Thai rider Ratthapark Wilairot. Wilairot was the only rider to score points on the bike, finishing 22nd in the championship with 30 points, and Bimota took tenth place among the constructors with the same 30 points.
Bimota did not take part in the 2011 season. The HB4 returned in 2012, again without scoring points.
