865cc / 904cc BigBore / Revisons Kit

Product information "865cc / 904cc BigBore / Revisons Kit"

Cylinder revision kit / displacement extension for air-cooled Triumph Modern Classic models - Bonneville / Thruxton / Scrambler.

Raisch Big Bore Kit 865cc or 904cc. Compression 10.5:1. for all engines. Displacement expansion for all 790cc engines or as a revision for 865 or 790cc engines that have already run a lot of kilometres. If you want to install the kit in your motorbike, you have to send us your cylinder (or the whole motorbike). These are then bored out and given a new Nikasil coating. This is significantly higher quality and more durable than new liners that are pressed in (as offered by other manufacturers).
Also included in the kit are the 2 new, original Triumph Thruxton 865cc pistons, as well as a cylinder head & base gasket.

For more details on the kit, give us a call and we'll give you the lowdown!
The 904cc kit is slightly more expensive (price on request).
