Very cleanly worked 50ccm Minachrome grey cast iron cylinder with oval outlet and straight manifold connection. Ideal replacement cylinder with a quite remarkable power development up to higher speeds. This makes it an absolute all-rounder and the first choice if you are looking for a reliable and powerful cylinder. The supplied Asso piston has a chrome-plated and a cast piston ring. The chrome plated piston ring should always be inserted in the top piston ring groove. The Top Performances Trophy cylinder kit should also be a good alternative to the most expensive serial parts in terms of price.

This kit comes with all gaskets but without cylinder head. The original head can still be used.
