CN250 280/290cc cylinder Kit 78mm with piston rings and gaskets.

These have been tough to get along with the forged kit we offer but this one is a little less and gives the power you are looking for from the CN250 used in everything from scooters such as Jonway YY250T to the CF Moto V3/V5 plus Hammerhead and Kinroad 250 go carts which really get a boast.

Can be used with stock head and cam. Adding an exhaust is a huge plus and doing trans at same time will give you a machine thats getting speeds of 75 when you need it. Alot of people claim 75 with stock parts but I doubt these speeds due to speedometers being not to correct on a lot of the Jonway scooters. The CF Moto bikes tell true speeds better.
