65cc cylinder kit for Derbi Flat Reed. Some really love this particular kit more than the others.
Aluminum with nikasil plating. 2 ring piston. Solid, reliable performance. Lots of room to get creative with porting. Some have reported issues running this with the stock Derbi head. You can always plug up your decomp or make the jump to one of the aftermarket options.
Comes with cylinder, piston, rings, pin/clips, hardware, and gasket set.
