Control functions 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): RST90 111.5 mm (4.39 in) RST90PGT 122.1 mm (4.81 in) Standard: RST90 112.5 mm (4.43 in) RST90PGT 122.1 mm (4.81 in) Maximum (hard): RST90 122.5 mm (4.82 in) RST90PGT 132.1 mm (5.20 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) Rear torsion springs EWS00750 (a) 1 1. Spring preload adjuster (b) Spring preload setting: Minimum (soft): S Standard: M Maximum (hard): H ESU14300 Adjusting the spring preload of the rear shock absorber (RS90P / RS90PLT) The spring preload can be adjusted by turning the adjusting nut on the rear shock absorber. 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). WARNING The left and right spring preloads must be adjusted to the same setting. Uneven settings can cause poor handling and loss of stability. To increase the spring preload and thereby harden the suspension, turn the adjuster in direction (a). To decrease the spring preload and thereby soften the suspension, turn the adjuster in direction (b). 40
