Supermonos

We have been supporters of the Supermono racing class since 1992, mostly campaigning a Suzuki DR800 motored entry. This bike has undergone yearly re-designs, with gradually increasing gains in power and handling (although you might not think so from the Assen post-crash picture below!).

The process has involved piston, cam and exhaust development, along with significant headwork, including downdrafting and re-shaping of ports and seats. We have paid careful attention to the reduction of friction and pumping losses. Through our experience campaigning the series, we are now able to offer oversize valves, pistons and racecams, plus engine reconditioning work and tuning for all Supermonos.
