STEERING TENSION ADJUSTMENT
Check the steering movement in the following procedure.
• By supporting the motorcycle with a jack, lift the front wheel
until it is off the floor by 20 – 30 mm (0.8 – 1.2 in).
• Check to make sure that the cables and wire harnesses are
properly routed.
• With the front wheel in the straight ahead state, hitch the
spring scale (special tool) on one handlebar grip end as
shown in the figure and read the graduation when the handle-
bar starts moving. Do the same on the other grip end.
 Initial force: 200 – 500 grams
 09940-92720: Spring scale
• If the initial force read on the scale when the handlebar starts
turning is either too heavy or too light, adjust it till it satisfies
the specification.
1) First, loosen the front fork upper clamp bolts, handlebar clamp
bolts, steering stem head nut and steering stem lock-nut, and
then adjust the steering stem nut by loosening or tightening it.
2) Tighten the steering stem lock-nut, stem head nut, handlebar
clamp bolts and front fork upper clamp bolts to the specified
torque and re-check the initial force with the spring scale
according to the previously described procedure.
3) If the initial force is found within the specified range, adjust-
ment has been completed.
NOTE:
Hold the front fork legs, move them back and forth and make
sure that the steering is not loose.
