ICON

- Lightweight aluminum cylinder with steel sleeve (huge weight savings over your stock cast iron cylinder)

- Cast in mounts on cylinder for aftermarket skid plates

- Oversized cooling fins on cylinder for efficient heat dissipation

- High compression 54mm piston with rings, pin, & clips (replaces your low compression dished or flat top piston)

- Head gasket kit

This will make a huge difference in performance over your stock setup and is a very quick and easy upgrade. For additional performance, add the 24mm or 26mm carb kit available in this section (both work great with this setup). This kit will work on all 86cc through 107 Chinese engines

Except models with a 3 valve head.the cylinder stud spacing is different on SDG 107 (SDG SPEED MINI 107)

Our Race Heads will work with your 2 valve head and will come with our huge Race Cam.
Additionally, our Race Head uses Honda type cams so there are many cam options available for your particular type of riding, unlike the limited selection of cams available for the Chinese heads. We recommend purchasing a high volume oil pump kit (available in this section).

Installation Note: It will save a lot of time and effort if the oil pump is installed while installing the bore kit (requires cylinder removal).

See the Performance Info section for additional information on our performance parts.

NOTE TRX90 will NOT need the hv oil pump AND We now have the cylinder set up for drop on install with no case mods
