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.

NOTE:

• TBW0473 cam is stronger through the low and mid range with a little less on the very top.
• TBW0577 cam is a little stronger on the very top with less through the low and mid range.

Key features:

• 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.

Application:

• Kawasaki Z125
