Here is the kit / cylinder - piston TNT, The cylinder is a basic AIRSAL T4, so it has 2 lateral transfers and 2 back transfers, nykasil is very good, aluminum too. Lepiston has a rear half moon in order to improve scanning. This cylinder with slightly higher than originally diagrams offer some extra performance. The finish of the channels is very propre.L'échappement ovalized is wider than the original rectangular.


This cylinder will be a very good compromise for a refurbishing of your original engine and this for a really attractive price.

The piston has 2 segments thickness of 1.5 mm, thinner than the original, they limit the friction and allow better high revs. For that price, what more!


The pack contains:
Piston Clips
Piston Pin

Pack seals
