What is the advantage of the improved connecting rod process?

The connecting rod features copper plating and heat-treating, which optimizes material properties. This leads to improved bearing wear and maximizes the rod's durability for longer service life.

Does this crankshaft assembly come with a bearing?

Yes, this assembly includes an OEM quality big end bearing. It is tested and inspected as a complete unit, ready for installation.

What does 'run-out and critical dimensions held to strict tolerances' mean for my bike?

This means the crankshaft has been precisely manufactured and measured to ensure it's perfectly straight and all key measurements are accurate. This ensures a proper fit and reliable operation within your engine.

Product Details

If you're rebuilding the engine in your 2004-2012 KTM 85 SX (17/14), this Wiseco crankshaft assembly is a solid option. It's the same assembly you'd find in their complete bottom-end kits, but offered individually. This makes it a straightforward way to get a reliable new crankshaft without having to buy a full kit if you don't need it.

Wiseco puts a lot of care into their connecting rod process. They use copper plating and heat-treating to optimize the material properties, which helps with bearing wear and makes the rod more durable. The surface treatment on the rod also helps smooth out any stress points, increasing its ability to handle load and extend its service life. The crank webs are precision machined and tested for strength, and the whole assembly is checked for run-out and critical dimensions to ensure it fits right and performs reliably.

This assembly comes ready to install, with an OEM quality big end bearing already in place and the timing keyway inspected for accuracy. It’s a well-built component designed to get your KTM 85 SX back on the track.
