Control functions ESU10874 Suspension The suspension can be adjusted to suit rider preference. Softer settings, for example, may provide greater rider comfort, while harder settings may allow more precise handling and control over certain types of terrain or riding conditions. If you are not familiar with suspension adjustments, have a Yamaha dealer make these adjustments. EWS00151 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). 3 1 (a) 2 (b) 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 1. Locknut 2. Distance A 3.
