This chain tensioner provides greater flexibility in the selection of primary gear ratios, allowing the use of chains with standard length 80, 81, 82 mesh and obtaining the desired primary ratio.
An important advantage of the universal chain tensioner is the possibility to adjust the tension of the chain never tightening and/or loosening the fixing screws of the plate on the weak supports of the crankcase. In fact, the tension will be flowing into the guides of the support.
Manufactured by Gran Turismo (UK) with high quality material, it fits perfectly to the engine crankcase.
