CYLINDER 155CC GY6

CYLINDER 155CC GY6 58.5mm Upgraded Cylinder Kit without the head by MRP This is normally the biggest you can go from a Vento Stock 52mm (125cc) or stock 57mm to the 58.5-59mm without boring out the engine and going to a machine shop. Choose between 59mm (157cc) which does not need engine bore and 62mm (177cc) which does require engine bore and we can help you with that also if you call. A larger head is a very good thing to add as well as exhaust to get best performance.
