This new chain tensioner is designed to keep a constant but light tension on the drive chain throughout swing-arm movement. The reduced stress and shock loads not only benefit and prevent premature lengthening of the chain but also reduce stress from wheel and gearbox output bearings.

Maintenance free chain tensioner.

Sprocket is lubricated by the chain so no need to lubricate separately.

Quick and easy to mount. Does not require any modification.
Complete with everything needed for installation and complete with instructions.

Fits Triumph Bonneville, Scrambler, Thruxton.
