| 57mm Bore Kit for Stock Honda-style Motor
I have a brand new, 57mm kit for the 50-based bike. The Piston will work if you have the 49.5mm china crank, 54mm takegawa crank, the 54mm dratv crank, the 56mm Moto-trade crank, or the 56mm 4-strokebikecentre.com crank. This is a long-type cylinder, 69mm tall with stock xr50 stud pattern.
Comes as shown. All new aluminum cylinder, japanese piston and japanese gasket set. Bore out your xr50 cases and run this.
49.5 crank makes 126cc
54 crank makes 138
56 crank makes 143 (like I run)
175 shipped.
