Very cleanly crafted Minachrom 50cc cast iron cylinder with oval outlet port. Ideal replacement cylinder with a fairly significant power increase up to higher revs. This makes it an absolute all-rounder and a top choice when looking for a reliable and powerful cylinder. The supplied Asso piston has a chrome and a cast piston ring. The chrome ring should always be used in the top ring groove. A well-priced alternative to the more expensive items in the range. The kit will include all gaskets, piston, 6 variator weights (5g) and clutch springs, but does not include the head, as the original head can be reused.
