TBPARTS - 165CC BORE KIT, RACE HEAD V2, INTAKE MANIFOLD KIT - Z125
This kit is the next step up from the 143cc kit, but requires case bore for it to fit. A great upgrade for your Z125, this kit uses a large, 64mm piston paired with a V2 race head to give a huge bump in power.
- Lightweight high compression 64mm piston
- Aluminum cylinder for better heat dissipation and further weight reduction from stock.
- V2 roller rocker race head provides much larger valves and aggressive cam with roller rocker arms.
- Kawasaki Z125
Case boring required
