CORONA, CA – June 2, 2021 – (Motor Sports NewsWire) – It’s important to make sure your engine is running its best so you can continue to be competitive in the world of supercross and motocross racing. That is why Pro Circuit works so hard to deliver quality high-performance engine parts to help our customer’s bikes run the best they possibly can. Our newest parts to help get the job done are clutch springs for the 2021 CRF450R and a kit for the 2018-2021 CRF250R that includes our Y-Radiator Hoses & Water Pump Cover with Impeller.

Our clutch springs for new CRF450R riders offer an increase in clutch life, decrease clutch slipping and improves engagement over a stock setup. The radiator hose and water pump cover kit for new CRF250R riders also increases performance. The Y-Radiator Hoses feature premium-grade silicone material that makes the hose kit able to withstand higher temperatures and pressures that the OEM hose cannot, while the water pump cover with impeller increases the pumping capacity and pressure head to reduce cavitation and increase cooling system performance. Our performance parts are essential upgrades every Honda racer should be lining up to the gate with to help separate themselves from the rest of the pack. 

Pro Circuit. We Race.
