Attention
Correct tightening of swinging arm screws (2) is
critical to rider and passenger safety.
Important
Improper chain tension will lead to rapid wear of
transmission parts.
Check the correspondence of the positioning marks
on both sides of the swinging arm to ensure a perfect
wheel alignment. Grease the wheel shaft nut thread
(1) with SHELL Retinax HDX2 and tighten it to a
torque of 145 Nm. Grease the adjuster screws (2)
thread with SHELL Alvania R3 and tighten them to a
torque of 10 Nm.
