PROX Crankshaft Bearing and Seal Kit - Husqvarna / KTM (Manufacturer's ref: 23.CBS64016): a set designed for the refurbishment of the crankshaft on motocross and roadster bikes. Designed to replace worn bearings and seals, this kit allows for a healthy mechanical base during an engine overhaul.

• Complete kit: bearings + crankshaft seals
• Treated bearings to minimise friction, contributing to smoother operation
• Suitable for off-road and light competition use, ideal for maintaining 4-stroke engines.

This PROX kit is aimed at riders who want to renew the engine's rotating assembly while respecting original tolerances. The seals ensure a tight seal around the crankshaft, while the treated bearings reduce friction and overheating during high revs.

Compatible with:

• KTM 450 SX-F (2025 - 450 cc)
• HUSQVARNA FC 450 (2025 - 450 cc)
• GAS GAS MC 450 F (2025 - 450 cc)

Practical advice: check the condition of the bearing housings and contact surfaces during installation. For optimal adjustment and long lifespan, have the installation checked by a professional if you are not equipped for pressing and alignment.
