ProX: Engine Parts and Repair Kits

ProX Racing Parts was founded in 1975 and is based near Amsterdam in the Netherlands. Its history is closely linked to internal engine components, with product families such as pistons, connecting rods and valves among its specialities. Over time, the brand expanded its range to include other motorcycle wear and maintenance parts. That development is reflected in the ProX selection at Motarea: replacement parts for work on the engine, clutch, fuel system and various chassis assemblies, with part numbers that must be chosen according to their specific application.

Pistons, Connecting Rods and Internal Engine Components

The ProX pistons and components range brings together parts for renewing the piston assembly and its associated components. Piston rings have their own section to make finding the corresponding replacement easier. Connecting rods and their components form another of the brand’s core product lines. Before choosing, identify the application part number, the stated dimensions and the kit contents: a category image does not replace checking which part the engine needs.

Work may also require engine bearings, oil seals or timing components. Each has a different role within the assembly, so it is useful to check the position and conditions shown on its product page. Selection should reflect the work being carried out and the condition of the components, without assuming that a kit includes items sold separately.

Clutch, Valves and Adjustment

ProX clutch parts include friction plates, separator plates, springs and basket or hub components. These parts allow different jobs within the same system; checking the contents of each part number helps prepare the repair. For the cylinder head, the valves and components section covers another important part of the catalogue. Valve adjustment parts also have a dedicated link to help locate the part number and size required for the intended adjustment.

Gaskets and Carburetion

ProX engine gaskets come in different configurations, including complete gasket kits and cylinder and top-end gaskets. Choosing the right assembly depends on which areas will be dismantled. Check the contents on the product page and distinguish the included gaskets from oil seals or other items that may require a separate part number.

For the fuel system, you will find jets and carburettor components alongside carburettor repair kits. The carburettor identification, application and stated calibration help determine the correct part. Replacement parts intended to repair an assembly and items used to adjust it have their own sections.

Repair Kits and Other Maintenance Parts

ProX repair kits extend the selection to assemblies such as the water pump, brake callipers, hydraulic pumps, steering, linkage and swingarm. The catalogue also includes clutch cables and hoses and suspension oil seals, dust seals and bushings, among other parts. Explore the links for each product family and consult the application, contents and fitting conditions on the product page to prepare your motorcycle’s maintenance with the parts it actually needs.
