INSTRUMENT AND CONTROL FUNCTIONS EAU14655 Adjusting the front fork EWA10180 WARNING Always adjust both fork legs equally, otherwise poor handling and loss of stability may result. This front fork is equipped with air valves for adjusting the spring rate. ECA10091 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) 1. Front fork air valve cap NOTICE To avoid damaging the front fork oil seals, do not exceed the maximum air pressure. Adjust the spring rate as follows. 1. Place the vehicle on the sidestand. TIP G 5. Securely install the air valve caps. 4 G When checking and adjusting the air pressure, there should be no weight on the vehicle. A low-pressure air gauge and an air pump are required to adjust the spring rate. These items are available at a Yamaha dealer. 3. Check the air pressure in each fork leg using a low-pressure air gauge. 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. 2. Remove the front fork air valve cap from each fork leg. 4-18
