Control functions NOTE: When removing the connector, the sound of air escaping may be heard, but this is from the pump hose, not the shock absorber. Air pressure range: 345 kPa (3.4 kgf/cm², 50 psi) to 1,034 kPa (10.3 kgf/cm², 150 psi) Recommended air pressure: RX10RTR 483 kPa (4.8 kgf/cm², 70 psi) RX10MTA 379 kPa (3.8 kgf/cm², 55 psi) ECS00730 RX10MT / RX10MTA 1 . Spring preload adjusting ring RX10RTR CAUTION: Do not exceed 1,034 kPa (10.3 kgf/cm², 150 psi). 7. Install the air valve cap. NOTE: If the front suspension bottoms too easily or rolls too much during cornering, increase the air pressure by 34 kPa (0.3 kgf/cm², 5 psi). If the suspension is too firm and you want a more compliant ride, decrease the air pressure by 34 kPa (0.3 kgf/cm², 5 psi). ESU10970 1 . Spring preload adjusting ring 2. Spring seat length Adjusting the rear suspension spring preload The rear suspension spring preload can be adjusted by turning the spring preload adjusting ring on the shock absorber (RX10R / RX10LT) or by turning the spring preload adjusting ring on the center shock absorber and the spring preload adjuster on the rear shock absorber (RX10RTR / RX10MT / RX10MTA). Spring preload setting at the center shock absorber (spring seat length or spring preload adjusting ring position): Minimum (soft): RX10MT / RX10MTA 1 RX10RTR 112.5 mm (4.43 in) Standard: RX10MT / RX10MTA 3 RX10RTR 113.5 mm (4.47 in) Maximum (hard): RX10MT RX10MTA 5 RX10RTR 123.5 mm (4.86 in) * The spring seat length changes approximately 1.5 mm (0.06 in) with each full turn of the adjusting ring. 26
