15. Adjusting the shock absorber length

Setting the shock absorber length
Sensitivity of the steering can be adjusted by
altering the length of the shock absorber, without
affecting other characteristics. The length is
adjusted using two nuts down and the treaded
clevis at the end of the piston rod (Fig.14). The
shock absorber can be adjusted up to 12 mm.
Adjusting the shock absorber length
A long shock absorber results in steeper inclination
of the front fork (steeper fork angle) and consequently
sensitive, quicker steering. A short shock absorber
gives a bigger angle of the front
fork (flat fork angle) and consequently slower and
smoother steering. Each complete turn of the shock
absorber gives one millimetre (Fig.15). The length
may never be altered more than to where the groove
(Fig.16) that is cut in the thread becomes just visible
under the lower nut of the level brachet. Make small
steps and test run.

14. Adjustment of shock absorber lenght

WARNING!

If the shock absorber has an
adjustable end eye/bracket, this
must not be threaded out more
than that one groove is fully
visible beneth the lock nut. Make
sure that the lock nut is tightened
after adjustment.

NOTE!

Ensure that the springs are properly preloaded
before attempting to make any adjustments. A
simple rule is that increased preload of the spring
should be followed by an increase of rebound
damping by two steps.

When you feel that you have achieved an im-
provement, go back to where you started and
check once more. Be observant of other relevant
factors such as tyres, temperature, etc. Test run
to make sure whether further fine adjustment
should be made.
