PROX Crankshaft Bearing 20x52x15mm — Manufacturer Ref. 23.6304SH
This bearing is designed to replace the original crankshaft component on motocross machines. This PROX bearing, with dimensions of 20 x 52 x 15 mm, allows for a clean restoration of the engine assembly during maintenance or repair due to wear or impact. Supplied individually, it installs in place of the original part to achieve precise alignment and limit axial play.
Suitable for the YAMAHA models listed for compatibility, such as YZ 85 LW Big Wheels 19/16 (2026), YZ 85 (2026), and YZ 65 (2026). Ideal for riders and mechanics looking for a precise replacement part for the crankshaft, allowing for the preservation of the geometry and play specified by the manufacturer during reassembly.
Be sure to check the condition of other engine group components (seal, circlips, cage) during replacement to ensure a clean and safe installation on your off-road machine.
