Crankshaft Seal Kit PROX - Beta RR (ref. 42.7350)
Specifically designed for motocross riders, this PROX seal kit puts sealing at the heart of engine preparation. Manufactured in Japan for recognized equipment manufacturers, these seals meet specifications and tolerances close to those of original parts, ensuring a precise fit on the crankcases. Ideal during an engine oil change, crankshaft replacement, or to prevent oil leaks on a demanding off-road machine.
These seals are designed to ensure sealing around the crankshaft and limit oil infiltration while withstanding the stresses of competitive 4-stroke engines. Their installation requires special care: thoroughly clean the seating surfaces, lightly lubricate the seal lips, and check alignment to avoid premature wear.
