143cc Forged V2 Big Bore Kit for Kawasaki Z125 Pro

TBparts NEW forged V2 piston 143cc big bore kit. If you already have the V2 Race Head and need a new FORGED PISTON 143cc bore kit, this is the one you want! It comes with all new high compression FORGED piston kit for the TBparts V2 Kawasaki cylinder head (They also work with the V1 and V1 style race heads). The all aluminum ceramic coated cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction (increasing power), improves sealing, and provides better heat transfer (runs and cools down quicker). This new cylinder along with a complete head gasket kit and domed piston set this kit apart from other similarly priced 143 kits on the market. Affordable and will make your Z125 or KLX110 a lot more fun to ride!  High quality parts and requires no machining to the cases or other modifications – bolt on and go!
