Description

The Wiseco B1003 top end bearing is engineered specifically for the demanding requirements of high-RPM CR250R engines, where bearing wear directly impacts power delivery and engine longevity. This precision component handles the extreme loads generated during competitive racing and hard riding, ensuring your top end maintains tight tolerances and smooth operation lap after lap. Running worn or substandard bearings compromises both performance and reliability—a quality bearing swap is one of the most cost-effective ways to restore your engine's responsiveness.
