cylinder kit Airsal Xtrem 78.5cc 50mm, 40mm for Minarelli AM

Airsal Xtreme 78.5cc Cylinder Kit is perfect for those not wanting to exceed the capacity in some racing series.

This 78.5cc version of the Xtreme cylinder has a 50mm bore for use on the standard stroke of a 40mm crankshaft. The maxed timing and Vertex pistons are identical to that of the 88cc Xtreme kit providing enough power. Machining of the crankcase is required due to the 50mm bore.

This kit should be run with a suitable racing exhaust exhaust system and 21mm carburettor.

Brutal power delivery, excellent quality and price put this kit up there with the best.
