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 Extended 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 piston and gasket kit for the Honda CRF50, XR50, and 1988+ Z50R. OEM quality & complete. This kit comes with the standard size piston, wrist pin, rings, and circlips and all necessary top end gaskets including the exhaust gasket.

Popular KLX Parts

TB 143cc Bore Kit, Performance Cam, Mikuni VM26, & Carb Kit

TBparts 143cc big bore kit, performance camshaft, Mikuni VM26, and carb kit for 2017+ KLX110s together in the best package deal! Starting with our 143cc big bore kit the performance gains are HUGE! It includes our all aluminum ceramic coated cylinder that is lighter than the OEM steel sleeved aluminum cylinder, reduces friction while improving sealing (increasing power), and provides better heat transfer (runs and cools down quicker). 

TB Primary Gear For Manual Clutch Kit

The primary gear is an upgrade/replacement for the primary KLX110 Clutch Kit 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.

monkey 125

The Monkey 125 is the hugely popular new kid on the block! Presently, we have big bore kits and few other items, but we plan to add a lot more parts to this category in the future. 

Popular monkey Parts

TB 149cc Big Bore Kit and 55mm Forged Piston

This will make your motorcycle a lot more fun to ride by adding some much needed power. With the larger bore, this bolt-on upgrade kit will give you more power and higher compression for a very reasonable price. This kit does not require boring of the case – simply bolt on, tune (Not included) and go!! 

TB Performance Exhaust, Carbon Fiber

Our new Monkey 125 Performance Exhaust was developed for performance, looks, and value. We felt an alternative was needed to the massive size of the stock and most aftermarket exhausts. We based this exhaust on our popular Z50 (the original “Monkey”) aftermarket performance exhausts that we have been selling for nearly 20 years. They increase performance while providing a clean and compact look that better fits the small Monkey in our opinion.

TB Chrome Chain Guard

TBparts chrome chain guard for your 2019+ Monkey 125 is the perfect upgrade over the stock plastic guard. Premium quality chrome plating for durability and vintage styling. It is very easy to install and will add a nice custom touch to your Monkey!
