This axle cassette is designed for the right - hand (engine side) and central bearing carrier. It's an optional part for 2011 OTK karts and newer models. With a 5mm offset, it offers a 5mm longer wheelbase compared to the standard cassette. It perfectly fits both 40mm x 80mm and 50mm x 80mm bearings, providing a reliable and high - performance solution for your kart.

Using this axle cassette is easy. First, make sure your kart is a 2011 OTK or newer model as it's designed for these. Decide whether you'll install it on the right - hand (engine side) or for the central bearing carrier. When installing, ensure it's properly aligned. The 5mm offset will give you a longer wheelbase, which can improve the kart's performance. As for maintenance, regularly check the bearings to make sure they are clean and well - lubricated. If you notice any signs of wear or damage, replace the cassette promptly to keep your kart running smoothly.
