Control functions EWS00151 WARNING Read and understand the following information before handling shock absorbers that contain highly pressurized nitrogen gas. G Do not tamper with or attempt to open the cylinder assemblies. G Do not subject the shock absorbers to an open flame or other high heat source. This may cause the unit to explode due to excessive gas pressure. G Do not deform or damage the cylinders in any way. Cylinder damage will result in poor damping performance. G Do not dispose of a damaged or worn out shock absorber yourself. Take the shock absorber to a Yamaha dealer for any service. ESU10894 3 1 (a) 2 (b) 1. Locknut 2. Distance A 3. Spring preload adjusting nut TIP The spring preload setting is determined by measuring distance A, shown in the illustration. The longer distance A is, the higher the spring preload; the shorter distance A is, the lower the spring preload. Spring preload setting*: Minimum (soft): RX10R / RX10LT 130.1 mm (5.12 in) RX10MT 134.6 mm (5.30 in) Standard: RX10R / RX10LT 134.5 mm (5.30 in) RX10MT 134.6 mm (5.30 in) Maximum (hard): RX10R / RX10LT 144.5 mm (5.69 in) RX10MT 144.6 mm (5.69 in) * Distance A changes 1.5 mm (0.06 in) with each full turn of the adjusting nut. 3. Tighten the locknut to the specified torque. NOTICE: Always tighten the locknut against the adjusting nut, and then tighten the locknut to the specified torque. [ECS00860] Tightening torque: Locknut: 42 Nm (4.2 m·kgf, 30 ft·lbf) Adjusting the spring preload of the front shock absorbers EWS00720 WARNING The spring preload of the left and right shock absorbers must be adjusted to the same setting. Uneven settings can cause poor handling and loss of stability. The spring preload can be adjusted by turning the adjusting nuts. 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). 25
