Description
The Wiseco Top End Bearing B1006 is engineered to handle the extreme demands of high-revving two-stroke engines found in competitive KX85 platforms. A worn or substandard bearing will compromise piston speed consistency, increase friction losses, and accelerate top-end wear—ultimately costing you performance and reliability on the track. This precision bearing delivers the durability and smooth operation required for sustained competitive performance.
Built from high-silicon aluminum alloy and case-hardened for extended service life, the B1006 maintains consistent clearances across the full RPM range, ensuring your engine runs at peak efficiency lap after lap. Whether you’re prepping for a season of racing or rebuilding a worn top end, this bearing is the OEM-quality replacement serious riders depend on.
