About Us

Founded in 1975 and currently headquartered in the Netherlands, ProX Racing Parts’ quality performance replacement components are now distributed in many countries worldwide. What started as selling OE replacement pistons in standard and oversize options grew into additional internal engine components and was eventually expanded into the US riding and racing market, supporting 90s Supercross and Motocross Champions such as Jeremy McGrath.

ProX is rooted in high-quality internal engine components including pistons, connecting rods, bearings, valves, clutch components, and gaskets for many applications across the powersports market, but our experience and passion has led us to expand our performance replacement part offerings across many components, including chassis and suspension, braking, controls, drivetrain, filters, fuel delivery, electronics, and more.

ProX stands true to their philosophy of providing OEM or better quality components at a more budget friendly price with each and every one of our parts. The ProX portfolio now consists over 10,000 part numbers divided over more than 60 different product groups. ProX components are manufactured by many of the same manufacturers that supply the OEMs, ensuring proven, reliable, and well-performing quality.

To this day, the vast crew behind ProX is decorated with fellow riders, racers and enthusiasts that are just as passionate about the sport as our customers, and that first-hand knowledge and experience continuously allows us to develop reliable performance products that will keep you out on the track or trail instead of in the garage.
