This axle cassette is designed for the right - hand side of the kart, which is the engine side. It's suitable for 2011 OTK karts and newer models with standard offset. It can fit both 40mm x 80mm and 50mm x 80mm bearings, offering great compatibility for your kart.

To use this axle cassette, first make sure your kart is a 2011 OTK or newer with a standard offset and is on the right - hand (engine) side. Then, carefully install the cassette ensuring it fits the 40mm x 80mm or 50mm x 80mm bearings correctly. When using, avoid overloading the kart to prevent damage to the cassette. For maintenance, regularly check the cassette for any signs of wear or damage. Clean it with a mild cleaner and keep it dry to extend its lifespan.
