Adjusting the shock absorber assembly

1. Spring preload adjusting nut
2. Locknut
   1. Increasing the spring preload
   2. Decreasing the spring preload

This shock absorber assembly is equipped with a spring preload adjusting nut.

WARNING Never attempt to turn an adjusting mechanism beyond the maximum or minimum settings.

1. Distance (spring preload)

Adjust the spring preload as follows.

1. Loosen the locknut.

2. To increase the spring preload and thereby harden the suspension, turn the adjusting nut in direction (a). To decrease the spring preload and thereby soften the suspension, turn the adjusting nut in direction (b).

NOTE:

• Use the special wrench included in the owner's tool kit to make the adjustment.
• The spring preload setting is determined by measuring distance A, shown in the illustration. The longer distance A is, the lower the spring preload; the shorter distance A is, the higher the spring preload. With each complete turn of the adjusting nut, distance A changes by 1.5 mm (0.059 in).
• When measuring distance A, the rear wheel must be raised off the ground.

Spring preload:

Minimum (soft): Distance A = 174.5 mm (6.87 in)
Standard: Distance A = 170 mm (6.69 in)
Maximum (hard): Distance A = 165.5 mm (6.49 in)

3. Tighten the locknut to the specified torque.

Tightening torque:

Locknut: 45 Nm (4.5 m-kgf, 32.5 ft-lbf)

CAUTION: Always tighten the locknut against the adjusting nut, and then tighten the locknut to the specified torque.

WARNING This shock absorber contains highly pressurized nitrogen gas. For proper handling, read and understand the following information before handling the shock absorber.

The manufacturer cannot be held responsible for property damage or personal injury that may result from improper handling.

• Do not tamper with or attempt to open the gas cylinder.
• Do not subject the shock absorber to an open flame or other high heat sources, otherwise it may explode due to excessive gas pressure.
• Do not deform or damage the gas cylinder in any way, as this will result in poor damping performance.
• Always have a Yamaha dealer service the shock absorber.
