4. Install the bolts.
5. Tighten to the specified torque.
6. Install the cushion.EBU33472Seat beltsThis vehicle is equipped with three-point seat
belts for the driver and passenger.Always wear the seat belts properly while rid-
ing in the vehicle. (See page 7-5.)
TIP
If the vehicle is driven without the driver
seat belt fastened, a buzzer will sound.
 If the vehicle is driven without the driver
seat belt fastened, engine power will be lim-
ited.
Tightening torque:
Driver seat bolt:23 N·m (2.3 kgf·m, 17 lb·ft)

TIPA special wrench can be obtained at a
Yamaha dealer to make this adjustment.
 The spring preload setting is determined by
measuring distance A, shown in the illustra-
tion. The shorter distance A is, the higher
the spring preload; the longer distance A is,
the lower the spring preload. With each
complete turn of the adjusting nut, distance
A is changed by 1.5 mm (0.06 in).
3. Tighten the locknut to the specified
torque. NOTICE: Always tighten the
locknut against the adjusting nut, and
then tighten it to the specified torque.

Rebound damping force
Turn the rebound damping force adjusting
screw in direction (a) to increase the rebound
damping force and thereby harden the damp-
ing, and in direction (b) to decrease the re-
bound damping force and thereby soften the
damping.Compression damping force
Fast compression damping force
To increase the fast compression damping
force and thereby harden the compression
damping, turn the fast compression damping
force adjusting bolt in direction (a). To de-
crease the fast compression damping force
and thereby soften the compression damp-
ing, turn the adjusting bolt in direction (b).

EBU31800Seat beltsMake sure that the seat belts are not frayed,
torn, stretched, or damaged. The seat belts
must move smoothly when pulled out and re-
tract on its own when released. The seat belts
must also lock up when quickly pulled out.
The latch plate should click securely into the
buckle and release when the release button is
pushed firmly. Wash off any dirt or mud that
could affect operation. Have a Yamaha dealer
repair as necessary for proper operation.
A crash can damage the restraint systems in
your vehicle. A damaged restraint system
may not properly protect the person using it,
resulting in serious injury or death in a crash.
To help make sure your restraint systems are
working properly after a crash, have them in-
spected and any necessary replacements
made as soon as possible.
EBU31810Passenger handholdCheck that the handhold bar and its supports
are in good condition. Confirm that the lock-
ing pins are securely fastened, and then push
and pull on the handhold to make sure that it
is not loose.EBU31820SteeringPark on level ground. Turn the steering wheel
right and left. Check for excessive free play,
abnormal noises, or a rough feeling. Have a
Yamaha dealer repair as necessary for proper operation.EBU31832Fittings and fastenersAlways check the tightness of chassis fittings
and fasteners before starting off. Take the ve-
hicle to a Yamaha dealer or refer to the Servi-
ce Manual for correct tightening torque.

seat.The maintenance information included in this
manual is intended to provide you, the owner,
with the necessary information for completing
your own preventive maintenance and minor
repairs.
The tools provided in the tool kit are sufficient
for this purpose, and should be kept on the
