Triumph Street Scrambler - Owner's Manual > Rear Suspension

Note:

• Street Twin, Street Cup, Street Scrambler, Thruxton, Bonneville T100 and Bonneville T120 suspension settings are spring preload adjustable only.
• Thruxton R suspension has three different rear adjustment settings; spring preload, rebound damping and compression damping.

The standard rear suspension preload settings provide a comfortable ride and good handling characteristics for general, solo riding. The following tables show suggested settings for rear suspension under different load conditions for all models.

Rear Suspension Preload Adjustment

Warning

Make sure that the adjusters are set to the same setting on both rear suspension units. Settings that vary from left to right may affect handling and stability resulting in loss of motorcycle control and an accident.

Street Cup, Street Twin, Street Scrambler, Thruxton, Bonneville T100 and Bonneville T120

Rear adjuster settings are counted from one with position one being with the adjuster turned fully anticlockwise.

There are five adjuster positions in total.

Position five gives the maximum amount of spring preload.

1. Rear suspension preload adjusters

The spring preload adjuster is located at the bottom of the rear suspension unit.

To change the rear suspension spring preload setting: Insert the adjustment tool (located in the right hand side panel) into the hole in the adjuster ring.

Turn the adjuster ring clockwise to increase spring preload, and anticlockwise to decrease spring preload. When delivered from the factory, the preload adjuster will be set at position one.

Rear Suspension Rebound Damping Adjustment - Thruxton R Only

1. Lower adjuster ring
2. Top adjuster ring

The spring preload adjuster is located at the top of the rear suspension unit.

To change the rear suspension spring preload setting: Use the two C-spanners located under the seat.

Hold the top adjuster ring in place with one C-spanner, and adjust the lower adjuster ring with the other C-spanner.

Turn the lower adjuster ring clockwise (viewed from above) to decrease spring preload and anticlockwise to increase spring preload. There are three defined positions to select from.

Rear Suspension Compression Damping Adjustment - Thruxton R Only

1. Rear suspension rebound damping adjuster

The rebound damping adjuster is located at the bottom of the rear suspension unit.

To change the rebound damping setting: Look upwards from the bottom of the suspension unit to the top of the suspension unit, and rotate the adjuster clockwise to increase and anticlockwise to decrease.

Note:

• The setting is measured as the number of adjuster clicks anticlockwise from the fully clockwise position.
• The motorcycle is delivered from the factory with the rebound damping adjuster set at the Standard setting, as shown in the relevant suspension chart

Rear Suspension Compression Damping Adjustment - Thruxton R Only

1. Rear suspension compression damping adjuster

The compression damping adjuster is located at the top of the rear suspension unit.

To change the compression damping setting: Rotate the adjuster clockwise to increase, or anticlockwise to decrease.

Note:

• The setting is measured as the number of adjuster clicks anticlockwise from the fully clockwise position.
• The motorcycle is delivered from the factory with the compression damping set at the Standard setting, as shown in the relevant suspension chart

Bank Angle Indicators

Warning

Use of a motorcycle with bank angle indicators worn beyond the maximum limit will allow the motorcycle to be banked to an unsafe angle.

Banking to an unsafe angle may cause instability, loss of motorcycle control and an accident.

Bank angle indicators are located on the rider's footrests.

Regularly check the bank angle indicators for wear.

Bank angle indicators must be replaced when they have reached the maximum wear limit of 5 mm in length.
