Front and rear brakes
Brake levers and brake pedal
Check that there is no free play in the front
brake lever. If there is free play, have a
Yamaha dealer adjust it.
Check for correct free play in the rear brake le-
ver. If the free play is incorrect, adjust it. (See
pages 8-101–8-103.)
Check for correct brake pedal height. If the
pedal height is incorrect, have a Yamaha deal-
er adjust it.
Check the operation of the brake levers and
pedal. They should move smoothly and there
should be a firm feeling when the brakes are
applied. If not, have a Yamaha dealer inspect
the brake system.
Brake fluid level
Check the brake fluid level. Add fluid if necessary.
(See pages 8-93–8-97.)
Recommended brake fluid: DOT 4

Do not exceed the maximum tongue weight.
You can measure tongue weight with a bath-
room scale. Put the tongue of the loaded trailer
on the scale with the tongue at hitch height. Ad-
just the load in the trailer, if necessary, to re-
duce the weight on hitch.
If you are carrying cargo and towing a trailer, in-
clude the tongue weight in the maximum vehi-
cle load limit.
Load cargo on the carrier as close to the center
of the vehicle as possible. Put cargo at the rear
of the front carrier and at the front of the rear
carrier. Center the load from side to side.
Tie down cargo securely to the carriers. Make
sure cargo in the trailer cannot move around. A
shifting load can cause an accident.
Make sure the load does not interfere with con-
trols or your ability to see where you are going.
