Chassis Construction

2003car003_half.jpg (72390 bytes)20030703_001_half.jpg (96623 bytes)As you can see in these two pictures, the chassis is fully triangulated. It is extremely rigid, yet light weight. The rear of the chassis is upswept to allow for a more efficient venturi to be installed and still clear the wishbones, etc. This chassis has been built around the Yamaha R-1 in dry sump configuration, but any modern motorcycle power unit can be used.
