TB V2 Race Head Kit & 54mm/95cc Piston Kit – Honda 50cc & 70cc Various Models
TBparts V2 Race Head Kit & 54mm/95cc Piston Kit. This kit includes everything needed to upgrade to our V2 Race Head on your Honda 50cc or 70cc that is equipped with a TBparts 54mm/95cc/117cc Big Bore Kit.
TBparts V2 cylinder head’s larger stainless steel (21-4N) valves, better porting, roller cam, and forged aluminum roller rocker arms that allow the engine to rev quicker, farther, and make much more power than other race heads. This cylinder head adds a professional level of performance at an affordable price for the privateer rider. These are high quality, bolt on parts! There are no installation instructions, but if you can replace your piston, you can install this kit. If you don’t have any experience working on your engine, we highly recommend having a professional technician install this kit or, at a minimum, purchasing the shop manual.

- 54mm High Compression Light Weight Piston Kit (91+ octane pump fuel friendly)
- 54cc Top End Gasket Kit
