Adjusting the spring preload of the
center shock absorber and the rear
torsion springs (RX10RTR / RX10MT),
or the rear shock absorber (RX10R /
RX10LT)
The spring preload can be adjusted by turning
the adjusting nut on the center shock absorb-
er and the adjusters on the rear torsion
springs (RX10RTR / RX10MT), or adjusting
ring (RX10R / RX10LT) on the rear shock ab-
sorber. Adjust the spring preload as follows.
Center

absorber
(RX10RTR /
RX10MT)
1.
Loosen the locknut.
2.
To increase the spring preload and there-
by harden the suspension, turn the ad-
justing nut in direction (a). To decrease
the spring preload and thereby soften the
suspension, turn the adjusting nut in di-
rection (b).
TIP
The spring preload setting is determined by
measuring distance A, shown in the illustra-
tion. The longer distance A is, the higher the
spring preload; the shorter distance A is, the
lower the spring preload.
3.
Tighten the locknut to the specified
torque.
NOTICE:
Always tighten the
locknut against the adjusting nut, and
then tighten the locknut to the speci-
fied torque.

WARNING
EWS00750
The left and right spring preloads must be
adjusted to the same setting. Uneven set-
tings can cause poor handling and loss of
stability.
To increase the spring preload and thereby
harden the suspension, turn the adjuster in di-
rection (a). To decrease the spring preload
and thereby soften the suspension, turn the
adjuster in direction (b).
