865ccm BigBore / Revisons Kit

Raisch Big Bore Kit 865 cc. Compression 10,5:1. for all engines. Displacement expansion for all 790cc engines or also as revision for the 865 or 790cc engines that have already run a lot of km. If you want to install the kit in your motorcycle, you have to send us your cylinder (or the whole motorcycle). These will then be bored and newly Nikasil coated. This is much higher quality and more durable than new liners that are pressed in (as other manufacturers offer).
Also included in the kit are the 2 new, original Triumph Thruxton 865cc pistons, as well as a cylinder head & foot gasket.
