✘ Inquire

The KOYO 6203-C3 crankshaft main bearing is a high-quality deep-groove ball bearing designed to OEM tolerances for small motorcycle and ATV crankshafts. Dimensioned 17 mm (ID) x 40 mm (OD) x 12 mm (width), it features a C3 (greater-than-normal) radial internal clearance, single-row open (unsealed) design, steel rings and balls, and a sheet-steel cage for reliable performance under continuous engine loads. Koyo lists a basic dynamic load rating around 12.0 kN and a static rating of about 4.80 kN, with limiting speeds typically around 17,000 min⁻¹ (grease) and 21,000 min⁻¹ (oil). This part is supplied to match OEM crankshaft bearing dimensions and is commonly used as a replacement for small-displacement Kawasaki, Suzuki and Yamaha engines (examples include models like the Yamaha PW50, Kawasaki KFX/LT-50 family and similar applications). Ideal for rebuilds and maintenance where precise fit, durability and correct C3 clearance are required.
