178cc Big Bore Performance Kit (67mm):

– Ceramic coated all aluminum cylinder (no steel sleeve)
– Lightweight high compression domed 67mm piston with rings, pin, & clips
– Head gasket kit – Now includes the cylinder head o-ring set and an exhaust gasket.

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 will provide the extra power to make your new Z125 a lot more fun to ride! These are high quality parts and definitely will dramatically increase the power and fun factor on your bike!

This big bore kit is recommended for use only with our V2 Race Head

Cylinder Skirt is 69×15.1mm, bore case to at least 70x16mm
