STEERING TENSION ADJUSTMENT

Check the steering tension as follows
• Support the motorcycle using a jack and raise the front wheel
off the floor 20 – 30 mm.
• Make sure that the cables and wire harness are properly
routed.
• With the front wheel pointing straight ahead, attach the spring
scale onto the end of the handlebar as shown.
• When the handlebar starts moving, record the reading on the
spring scale. This reading is referred to as the "initial force".
• Repeat the same procedure on the end of the other handle-
bar.
& Initial force: 200 – 500 grams

stem head nut. Then, adjust the steering stem nut by either
loosening or tightening it.

the initial force as described above.

is within specification.

Hold the front fork legs, move them back and forward. Make
sure that the steering is not loose.
