Adjusting the chain tension

Move the bike slowly so as to find the position where chain upper section is more tensioned.

Set the motorcycle on the side stand.

Measure chain tension at the centre of the lower section, with the motorcycle on the side stand: lower the chain by pressing down on it only with your finger, release it and measure the distance between the centre of the chain pins and the aluminium section of the swingarm.

It must be: A = 38 ÷ 40 mm.

To adjust the tension remove the rear splash guard

Slacken off the two screws (1) that secure the rear wheel hub to the swinging arm.

To make the procedure clearer the rear wheel has been removed.

Using pin wrench (A) no. 88713.1038 inserting its tooth in the eccentric hub (2).

Rotate the eccentric hub (2) to obtain the correct chain tension.

Turn counter clockwise to tighten the chain; clockwise to loosen (from chain side view).

Refit the rear splash guard
