Domestic and international dealers and distributors are being served from our facility in the Netherlands. The business is conveniently located in Nieuw Vennep, approximately 30 minutes from our capital, Amsterdam, and only 15 minutes from Schiphol International Airport.
ProX Racing Parts mainly specializes in high-quality internal engine components and replacement parts such as pistons, connecting rods, crankshafts, and valves.

ProX Racing Parts stocks well over 8,000 part numbers divided over 60 different product groups.
ProX offers replacement parts from braking and suspension to fueling, steering, engine rebuild, air filters, and oil filters. All parts are manufactured to the highest quality standards at “state of the art” manufacturing facilities worldwide. These manufacturing factories include reputable businesses that manufacture OEM (Original Equipment Manufacturing) parts for leading motorcycle brands worldwide. ProX aims to deliver OEM quality replacement dirtbike parts, atv parts, utv parts, snowmobile parts, scooter parts, Jetski parts, and motorcycle parts.

Awesome to see the expansion of your product line. I've used your piston kits for many years now and found them to be excellent quality. In the early day of PROX, your pistons were made by ART, same company that made pistons for 3 of the Jap bike manufacturers. Literally the same, yet cheaper because not in a factory package! That's how I started with Pro-X and never looked back. 45 yrs a tradesman motorcycle mechanic and I choose, Pro-X first, every time! 😉
Simple maintenance is the path to avoiding expensive repairs ✨️ We have you covered with quality parts made by OE and leading suppliers for any job! 🔧

New piston time for your 4-stroke? It's always a good idea to replace the cam chain while you're in there – A worn out cam chain can lead to failure and very expensive repairs.
Our cam chains are made by Borg Warner – A trusted OEM supplier. Find everything you need at Pro-X.com or wherever you like to buy#proxs#camchain #maintenancea#topendc#MotorcycleMaintenancea#4strokemaintenanceaintenance

I just cannot justify your cam chain for $90 vs OEM on partzilla for $30. For a 07 YFZ450. Also I ordered a top end gasket kit, whoever did the packaging put 3 exhaust valve seals and 2 intake valve seals in the kit instead of the 2 exhaust and 3 intake that it is supposed to be. Not to bash or anything, otherwise quality of parts have been great between my clutch kit and con rod.
Can you tell me know which chain I want for a xl600r please? Tried on your site but no answer
Shame you don't do a rod kit for a 390rr beta
HUGE win for Seth Hammaker and the Pro Circuit Racing crew in Indy for the East/West Showdown. This one means a lot and we're honored to be a part of#proxpoweredwered#prox##supercrossc#procircuitr#Kawasakiasaki

Funny but every bike I’ve owned over the past 47 years the front sprocket wore out quicker than the rear.
Wouldn’t it be cheaper to buy a new one?
Dam new bikes! The old bikes ran forever just change oil a couple times a year! Still have a 1972 SL 70 that runs very good!
Ur missing something’s
Haha just seen this in my memories
Companies like Factory Motocross Vacations need a reliable source for quality replacement parts that don't break the bank, which is exactly why this KTM 350 SX-F build done in collab with @dirtbiketv1 got fresh brake rotors and pads, chain and sprockets and various bearing kits throughout the wheels and chassis. Find the ProX components you need wherever you buy parts or at Pro-X.com 🔧
