The PROX brand has been one of the main brands of technical spare parts for off-road motorcycles since 1975. Today, however, the range also includes an extensive range for ATVs (Quads), jet skis (PWC / Jet-Ski), snowmobiles and small mopeds and scooters up to 50cc.

PROX products are manufactured in Japan and the USA with an emphasis on perfect quality in order to achieve a long service life even in demanding racing conditions. Therefore, they were and are used as racing and tuning parts for the aftermarket (replacement for original parts), but now the Prox brand is also a major supplier to the original production (OEM Supplier) of world-famous brands.

Another proof of quality and trust is the use of PROX products by riders and racing teams that participate in world-class races.
