Adjusting steering head angle (999)
Before changing steering head angle, you must first
remove the steering damper. Unscrew the retaining
screws (1 and 2) to release the steering damper. The
steering lock peg (3) is retained with a screw (2) and
must be re-positioned farther back on refitting when
steering head angle is modified.
Slacken the steering head retaining screw (4).
To change steering head angle, remove the circlips (6)
and the washers (7) and loosen the two screws (5) on
E
the frame right side.
Fully unscrew the screw (8) and turn the steering tube
eccentric (9) by 180° with a pin wrench.
Check that the hole on the eccentric is centred with the
through hole in the steering tube. Look at the arrow
etched in the top area of the eccentric to centre both
holes accurately.
Fully screw the screw (8). Grease the threads of the
screws (5) with SHELL Retinax HDX2 and tighten to 22
Nm. Refit the washer (7) and the circlip (6).
Note
While performing the above, the handlebars should
not be fully turned.
