OTK Chain Stretcher M10 Short 125cc KZ

The OTK Chain Stretcher M10 Short 125cc KZ (part number 0110.A0) is a genuine OTK chain tensioning bolt used to set and maintain correct chain tension on OTK-based kart chassis running the 125cc KZ (shifter) engine class. This is the short version of the OTK M10 chain stretcher, designed for KZ engine mount configurations which require a shorter bolt than the 100cc OK/KF long version (0110.B0). It threads into the engine mount bracket to push against the engine plate and tension the drive chain to the correct specification.

KZ class karts use a 6-speed sequential gearbox and place significant demands on the drive chain compared to direct-drive classes. Maintaining correct chain tension is particularly important in KZ applications, where chain wear and tension changes can occur more quickly. The OTK M10 chain stretcher allows precise tensioning adjustment and is engineered for reliable operation across a race weekend.

Buying Advice

This is the short version (0110.A0) for KZ shifter applications. If you run a 100cc OK or KF class engine, you need the long version (0110.B0). The jam bolt (0110.B0A) is a separate part used to lock the chain stretcher adjustment once tension is set — see the chain stretcher jam bolt listing.
