Cylinder Kit 70cc TopPerformance Trophy
Very durable minachrome/cast-iron cylinder with oval exhaust port and 6 transfer ports. The excellent performance delivery even in higher revs makes this a real all-rounder and your first choice if a reliable and strong cylinder is what you're after. The Asso piston included in the delivery has a chrome-coated and a cast ring. The chrome-coated ring should always be placed into the top grove. This cylinder has a very high squish clearance.
Kit complete with gaskets, piston and head
