MAINTENANCE AND LUBRICATION
Brakes
Brake Fluid Check
Check brake fluid levels before each use of the vehicle.
The brakes should feel firm when they’re applied. Spongy or weak
brakes may indicate a fluid leak or low fluid level. A low fluid level
may also mean that brake pads are worn and need to be replaced. Do
not operate the vehicle with spongy or weak brakes. See your dealer for
service.
Master Cylinder (Handlebar)
The master cylinder (1) is
located on the left
handlebar. View the fluid
level through the indicator
window (eye) on the top of
the master cylinder.
A dark eye (2) indicates a
full fluid level.
A clear eye (3) indicates a
low fluid level.
Master Cylinder (Foot Brake)
The foot brake master
cylinder (4) is located under
the right rear fender. View the
fluid level through the reservoir
body. Fluid level is full at the
MAX mark. Add brake fluid if the
level reaches the MIN mark.
WARNING
Once open, a bottle of brake fluid absorbs moisture from the air,
which causes the boiling temperature of the brake fluid to drop.
This can lead to early brake fade and the possibility of accident.
Do not store opened brake fluid. Properly discard any unused
portion.
