INSTRUMENT AND CONTROL FUNCTIONS EAU14802 Spring rate: Minimum (soft): Air pressure = 0 kPa (0 kgf/cm², 0 psi) Standard: Air pressure = 0 kPa (0 kgf/cm², 0 psi) Maximum (hard): Air pressure = 50 kPa (0.5 kgf/cm², 7.1 psi) Adjusting the shock absorber assembly This shock absorber assembly is equipped with an air valve for adjusting the spring rate. ECA11090 NOTICE Never exceed the maximum air pressure, otherwise the oil seal may become damaged. Adjust the spring rate as follows. 1. Place the vehicle on the sidestand. TIP When checking and adjusting the air pressure, there should be no weight on the vehicle. 2. Remove the air valve cap. 4 1. Front fork air valve cap 5. Securely install the air valve caps. 3. Check the air pressure in each fork leg using a low-pressure air gauge. A low-pressure air gauge is available at a Yamaha dealer. 4. To increase the spring rate and thereby harden the suspension, increase the air pressure with an air pump. To decrease the spring rate and thereby soften the suspension, decrease the air pressure by pushing each valve stem down. 4-18
