Bye Bike 47mm "70cc" Cylinder Kit
Bye Bike 47mm "70cc" cylinder kit!
This cylinder is made specifically for the Bye Bike and no other engine. Bolts on perfect and rips! We really like this cylinder paired with a 19mm Dellorto PHBG on the stock intake.
Aluminum cylinder. 2 ring piston. Auxiliary exhaust ports. This kit provides incredible power.
Comes with cylinder, piston, pin/clips, rings, and gasket set.
