Discover this brand - new style two - bolt sprocket hub, specifically designed for OTK karts. It features a 50mm axle, providing a perfect fit. The sprocket mounts only to one side of the hub, ensuring efficient power transmission and easy installation.

Using this sprocket hub is easy. First, make sure your kart is turned off and in a safe, stable position. Then, align the 50mm axle of the hub with the corresponding part on your OTK kart. Mount the sprocket on one side of the hub as it's designed. When it comes to maintenance, regularly check the bolts for tightness. If they seem loose, use a proper tool to tighten them. Keep the hub clean by wiping it down with a dry cloth after each use. Avoid exposing it to extreme temperatures or harsh chemicals, as this could damage the magnesium material.
