ProX Racing Parts: Dutch Precision, Global Performance
When it comes to squeezing every ounce of performance from your engine, true riders know that the right parts make all the difference. For nearly 50 years, ProX Racing Parts has been the quiet force behind countless victories and reliable rebuilds, earning a reputation for quality that stretches from the motocross tracks of Europe to the off-road trails of America.
A Legacy Born in the Netherlands
Founded in 1975 near Amsterdam, ProX Racing Parts started with a simple mission: deliver OEM-quality engine components to racers and enthusiasts worldwide. Today, ProX is a global powerhouse, supplying over 10,000 part numbers across more than 60 product groups. Whether you’re building a race engine or just keeping your weekend warrior in top shape, ProX’s commitment to precision and durability is legendary.
Trusted by Champions, Chosen by Riders
ProX isn’t just a name you see on the box—it’s a name you see on the podium. Their parts are trusted by professional teams and their partnerships reinforce their status as a leader in high-performance components. From ultralight steel rear sprockets to complete engine rebuild kits, ProX is all about giving riders the edge, whether you’re chasing a championship or just chasing the next corner.
What Makes ProX Different?
Unlike many aftermarket brands, ProX Racing Parts are manufactured in the same factories that produce OEM components for the world’s biggest motorcycle brands. That means every piston, bearing, and gasket is built to the same exacting standards as the parts your bike was born with. Their catalog covers everything from pistons and crankshafts to clutch kits, valve train parts, and even drivetrain components. And with a focus on both two-stroke and four-stroke engines, ProX has something for every rider—no matter what you ride.
