The mark on our Cylinder is 49.9cm3, but the actual displacement is 70cm3 or 70cc(the inner diameter of the stock cylinder(or the original cylinder is 40mm while this big bore cylinder is 47mm.)). Considering it is not legally allowed in most countries to rebuild a scooter with big bore parts, we mark it 49.9cm3 on cylinder.

Application: VENTO  ZIP; QJ/KEEWAY 50cc 2 stroke scooters such as Hurricane 50, F-act 50, Matrix 50, RY8 50, Venus 50 produced after 2006.

Caution: If your bike has a 10mm piston pin(Piston hole Diameter or piston pin diameter), this big bore kit doesn't fit. The piston kit for Scooters of JOG50 series is the 10mm one.

We carry JOG70 47mm big bore kit with 10mm piston pin too. This is the link of the 10mm one:
