Front and rear shock absorber assemblies

YXF10WRAN / YXF10WRZN:

The shock absorber assemblies are equipped with a spring preload adjusting nut and a compression damping force adjuster.

YXF10WRLN:

The shock absorber assemblies are equipped with a spring preload adjusting nut.

This vehicle is also equipped with a suspension mode switch which makes it possible to adjust the damping force. See page for more information on selecting the suspension mode.

  • Suspension components become hot during operation. Never touch the compression damping force adjuster or the oil reservoir with your bare hand or skin until suspension components have cooled.
  • Always adjust the shock absorber assemblies on the left and right side to the same setting. Uneven adjustment can cause poor handling and loss of stability, which could lead to an accident.

Never turn an adjusting mechanism beyond the minimum and maximum settings.

Spring preload

  1. Elevate the vehicle and place a suitable stand under the frame.

  2. Loosen the locknut.

  3. Turn the spring preload adjusting nut in direction (a) to increase the spring preload and thereby harden the suspension, and in direction (b) to decrease the spring preload and thereby soften the suspension.

    3. Special wrench
    • A special wrench can be obtained at a Yamaha dealer to make this adjustment.
    • The spring preload setting is determined by measuring distance A, shown in the illustration. The shorter distance A is, the higher the spring preload; the longer distance A is, the lower the spring preload.
    Front spring preload setting:
    Minimum (soft):
    Distance A = 519.3 mm (20.44 in)
    Standard:
    Distance A = 509.3 mm (20.05 in)
    Maximum (hard):
    Distance A = 499.3 mm (19.66 in)
    Rear spring preload setting:
    Minimum (soft):
    Distance A = 475.2 mm (18.71 in)
    Standard:
    Distance A = 460.2 mm (18.12 in)
    Maximum (hard):
    Distance A = 445.2 mm (17.53 in)

  4. Tighten the locknut to the specified torque. NOTICE: Always tighten the locknut against the adjusting nut, and then tighten it to the specified torque.

    Tightening torque:
    Locknut:
    41 N·m (4.1 kgf·m, 30 lb·ft)
Compression damping force (if equipped)

  1. To increase the compression damping force and thereby harden the compression damping, turn the compression damping force adjuster in direction (a). To decrease the compression damping force and thereby soften the compression damping, turn the adjuster in direction (b).

These shock absorber assemblies contain highly pressurized nitrogen gas. Read and understand the following information before handling the shock absorber assemblies.

  • Do not tamper with or attempt to open the cylinder assemblies.
  • Do not subject the shock absorber assemblies to an open flame or other high heat source. This may cause the unit to explode due to excessive gas pressure.
  • Do not deform or damage the cylinders in any way. Cylinder damage will result in poor damping performance.
  • Do not dispose of a damaged or worn out shock absorber assembly yourself. Take the shock absorber assembly to a Yamaha dealer for any service.
