Popular CRF50 Products

TB Race Head, 88cc Bore & 20mm Carb Kit

Our Race Head has been updated for even more performance!  It now has 25/22mm valves with better porting/flow.  We also kept the combustion chamber the same size and changed the angle of the valves slightly. This will really wake up your stock engine and is comparable in power to the much larger Chinese 124cc engines!!!

TB Brake Pedal

This high quality Z50R 80-99, All XR/CRF50 & XR/CRF70 Brake Pedal is identical to the OEM version except we added 1 inch of length to it for adult riders (or older kids).  There is no reason to spend a lot of money after you mangle your brake pedal or simply want to replace an ugly rusted out one when we have this one at a great price!

TB Complete Gasket Kit plus Oil Seal Kit

OEM high quality complete Gasket Kit A and B (top and bottom end) combined with an Oil Seal Kit for all 1988 and up Z50, XR50, and CRF50 models.

Popular KLX Parts

TB 143cc Bore Kit, Race Head V2, and VM26mm Carb Kit

This kit is similar to our other complete 143 kit but includes our Race Head V2, camshaft, and a larger intake manifold. While the this head may appear to be the same on the outside as our other race head, internally it has gone through numerous changes.

TB Manual Cluth Kit – Primary Gear

The Primary Gear is an upgrade/replacement for the Primary Clutch Removal Washer (which removes pounds of rotating mass and improves throttle response) that is included in the TB Manual Clutch kit and similar kits. It allows for removal of the entire clutch assembly while removing any chance of slippage possible with the washer – It transfers 100% of your engine power to the clutch and is highly recommend for KLXs/DRZs
