When you're rebuilding the engine on your 2003-2008 KTM 65 SX, a solid crankshaft is key to getting back on the track. This crankshaft assembly from Wiseco is built to be a reliable replacement, using the same components found in their complete engine rebuild kits. It's designed to be a direct fit, meaning it's tested and inspected to ensure critical dimensions are held to strict tolerances right out of the box.

Wiseco puts a lot of attention into the connecting rod process for this assembly. They use copper plating and heat-treating to optimize the material's properties, which helps improve bearing wear and maximize durability. The surface treatment on the connecting rod also works to remove residual stress risers and smooth out surface blends, further increasing its ability to handle load and extend its service life. The crank webs are precision machined and tested for strength, and an OEM quality big end bearing is used in the assembly, ensuring dependable performance.

This crankshaft assembly is a well-built option if you're looking for a quality replacement without needing a full engine kit. It's ready to install and has been inspected to meet strict run-out and dimension requirements.
