Description
Top end bearings are critical wear items in two-stroke engines—they directly impact crankshaft stability, reduce parasitic friction losses, and extend engine longevity under high RPM loads. The Wossner N1022 is a precision replacement bearing engineered to OEM tolerances, ensuring your RM250 maintains consistent power delivery and reliability whether you’re racing or rebuilding.
This bearing restores proper clearances in your top end, eliminating play that compounds over time and degrades performance. Installing a quality bearing during routine maintenance or engine refresh prevents catastrophic failure and keeps your two-stroke running at peak efficiency.
