This axle cassette is designed specifically for the left side of the kart, which is the brake side. It is an optional part for OTK karts manufactured in 2011 and later. With a 5mm offset, it provides a 5mm longer wheelbase compared to the standard cassette. It perfectly fits 40mm x 80mm and 50mm x 80mm bearings, ensuring smooth and stable performance for your kart.

Using this axle cassette is easy. First, make sure your kart is from 2011 or newer and it's the left side (brake side) that you're working on. Then, install it carefully, ensuring it fits well with the 40mm x 80mm or 50mm x 80mm bearings. When using the kart, keep an eye on the axle cassette for any signs of wear. For maintenance, clean it regularly to prevent dirt and debris from building up. If you notice any problems, replace it as soon as possible to keep your kart in good condition.
