§ 02 / About this part
What it is
The ATHENA ENGINE BEARING 63/22 C4-KOYO, bottom end. Stocked by Iron Offroad, the UK MX hard parts specialist.
This 63/22 C4 bearing is engineered for high-performance bottom-end assemblies. The C4 clearance is specifically designed to handle the extreme thermal expansion found in race-tuned engines. It is a direct replacement for OEM parts 91002KE1014 and 91002KY4901. These bearings are critical for supporting the crankshaft or gearbox shafts under heavy load. Replace them during your scheduled engine strip-down to avoid unexpected failures on the track. Ensure the bearing is pressed in straight using the correct tools to avoid damaging the internal races or the engine cases.
