PROX Crankshaft Bearing and Oil Seal Kit — Manufacturer's ref: 23.CBS61009

This PROX kit includes the bearings and oil seals necessary to refurbish the crankshaft of a motocross engine. Designed to restore smooth rotation and controlled sealing, it allows for the replacement of worn parts during engine disassembly or complete refurbishment. The bearings are treated to reduce friction, and the oil seals ensure protection against oil loss and infiltration.

• Complete kit: bearings + oil seals for crankshaft
• Treated bearings to reduce friction
• Restores the original sealing and rotation of the crankshaft
• Intended for motocross use and small single-cylinder engines (e.g. 65 cm³)

Ideal for mechanics and DIY enthusiasts looking to renew the crank assembly, this kit is used during an engine service to eliminate excessive axial or radial play and prevent oil loss due to degraded seals. However, please check the references and dimensions before installation to ensure compatibility with your model. Examples of affected models: KTM 65 SX (2025), GAS GAS MC 65 (2025), HUSQVARNA TC 65 (2024).
