OTK Chain Stretcher M10 Long 100cc

The OTK M10 Chain Stretcher Long 100cc (part number 0110.B0) is a genuine OTK tensioning bolt used to set and maintain correct chain tension on OTK-based kart chassis. This is the long version, designed for use in 100cc OK and KF class applications. Finished in red anodising, it threads into the engine mount bracket to push against the engine plate and tension the drive chain to the correct specification.

Maintaining correct chain tension is one of the most important setup tasks on a kart. Too loose and the chain risks skipping or derailing; too tight and it places excessive load on the engine sprocket, rear axle bearings and the chain itself, increasing wear and reducing performance. The OTK chain stretcher allows precise tensioning adjustment without the need for additional tools and is designed for repeated adjustment across a race weekend.

Buying Advice

OTK produces several chain stretcher variants — standard length, long, and a separate jam bolt (0110.B0A). This listing is for the long red M10 stretcher bolt (0110.B0) used in 100cc OK/KF applications. If you run a 125cc shifter or require a different length, check the 0110.A0 variant. The jam bolt (0110.B0A) is a separate part used alongside this stretcher to lock the adjustment once tension is set. Both parts are available individually from IC Kartstore.
