Bimota will be debuting with FB Corse in the Moto2 series with this Bimota HB4. It should prove to be an exciting bike with a Honda engine (from the Honda CBR 600 RR), and a stunning Bimota trellis chassis of steel and cast magnesium.

Out of the shadows of the Italian track Binetto, we can see that the HB4 features a steel and cast magnesium trellis frame. Helping put the production-based Honda motor right where the team needs it, the chassis also features an adjustable steering head and engine mounts system.

The swingarm is impressively built, and features a linkage to the custom exhaust developed by Zard. Suspension is done by Paioli up front, and Öhlins in the back. 300mm Braking disc-brakes are stoppped by Brembo monoblocs to help slowdown the 297lbs motorcycle.

Other features include an aeronautical system for the frame, adjustable steering head and forged magnesium wheels. The Bimota HB4 weighs 135 kg (dry) and has a 21-litre capacity fuel tank. Rumours say that if the bike is successful and generates enough interest, we could see a production version turn up.

As only the 4th time a Honda motor has been put in a Bimota chassis, the HB4 marks a nearly 25 year drought of the Italian company sourcing its motors from winged-motor brand. On the racing front, Bimota won its first world championship back in 1980 with Jon Ekerold, and then in 1987 with Virginio Ferrari.
