Quick Overview

As our American cousins like to say ‘there is no substitute for cubes’ If you want get some extra performance from your Bonneville, this is the way to go. This top quality kit is the result of a collaboration between ourselves & WISECO Inc. of USA. Torque is raised by 50% & power by 40%! The increased torque at low revs means that the bike really pulls well, whilst the power increase means that it keeps pulling right to the rev. limiter! So whether you just want improved throttle response for easy riding or whether you want extra power at the top end-this is the favourite way to get there. Kit consists of pistons, liners, gaskets etc. Price includes all machining work on your cylinder barrel.
We are now able to offer a UK fitting service for a very competitive price. Please contact us for further details

Power and torque figures are gains on 790cc engines.
