Description
Every crankshaft rebuild comes down to the bearings that hold it centered in the cases, and this Wiseco main bearing is built to the 25 x 62 x 17mm dimension used in that position.
As a main bearing wears, the crankshaft can develop play that shows up as vibration, noise, or an uneven engine feel well before the bottom end actually fails. Because the crank rides directly on these bearings at full engine speed, replacing them anytime the cases are split is standard practice rather than an optional step. Wiseco has this bearing produced by the same manufacturers that supply bearings to OEM assembly lines, including leading Japanese bearing makers, so it’s built to the same standard as what came out of the factory.
- Measures 25mm bore x 62mm outside diameter x 17mm width for a direct fit
- Manufactured by the same suppliers that build bearings for OEMs, including leading Japanese manufacturers
- Precision machined and finished with quality materials
- Inspected for accuracy before it ships
- Inspected for function to confirm smooth, consistent rotation
- Inspected for cleanliness to protect the crank and case bearing surfaces
- A dependable replacement any time the cases are open for a bottom-end rebuild
For a bottom end that specifies a 25 x 62 x 17mm main bearing, this Wiseco bearing is machined and checked to the same fit and finish as the original equipment it replaces.
