Dirt Bike Radiators, Hoses and Cooling Parts
Heat kills engines. Tight woods trails, slow technical sections and long motos in the summer push a dirt bike's cooling system hard, and a bent radiator or tired water pump is all it takes to boil over. Keeping the cooling system in shape protects your top end and keeps power consistent from start to finish.
We stock replacement radiators, silicone hose kits, water pump rebuild kits from ProX, Boyesen water pump covers and impellers, and radiator guards from DeVol and Works Connection to keep a tip-over from turning into a leak. Add a fan kit if you ride a lot of slow terrain where airflow is limited.
Topping off or flushing? Pick up coolant in oils and chemicals. If your bike is running hot after a rebuild, double-check your engine parts and jetting in fuel and intake.
Cooling parts are model specific, so match your year and model before ordering. If you're chasing an overheating problem and don't know where to start, reach out and we'll point you in the right direction.
