This shock absorber contains highly
pressurized nitrogen gas. For proper
handling, read and understand the
following information before
handling the shock absorber. The
manufacturer cannot be held
responsible for property damage or
personal injury that may result from
improper handling.
•Do not tamper with or attempt
to open the gas cylinder.
•Do not subject the shock absor-
ber to an open flame or other
high heat sources, otherwise it
may explode due to excessive
gas pressure.
•Do not deform or damage the
gas cylinder in any way, as this
will result in poor damping per-
formance.
•Always have a Yamaha dealer
service the shock absorber.

The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or
loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual
inspection, to check the following points before each ride.

Braking
1. Close the throttle completely.
2. Apply both front and rear brakes
simultaneously while gradually
increasing the pressure.
EW000057
•Avoid braking hard or suddenly
(especially when leaning over
to one side), otherwise the
scooter may skid or overturn.
•Railroad crossings, streetcar
rails, iron plates on road cons-
truction sites, and manhole
covers become extremely
slippery when wet. Therefore,
slow down when approaching
such areas and cross them with
caution.
•Keep in mind that braking on a
wet road is much more difficult.
•Ride slowly down a hill, as
braking downhill can be very
difficult.

SCOOTER CARE AND STORAGE

Care
While the open design of a scooter
reveals the attractiveness of the
technology, it also makes it more
vulnerable. Rust and corrosion can
develop even if high-quality
components are used. A rusty exhaust
pipe may go unnoticed on a car,
however, it detracts from the overall
appearance of a scooter. Frequent and
proper care does not only comply with
the terms of the warranty, but it will also
keep your scooter looking good, extend
its life and optimize its performance.Before cleaning
1. Cover the muffler outlet with a
plastic bag after the engine has
cooled down.
2. Make sure that all caps and covers
as well as all electrical couplers
and connectors, including the
spark plug cap, are tightly
installed.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such
products onto seals, gaskets and
wheel axles. Always rinse the dirt
and degreaser off with water.CleaningECA00011
•Avoid using strong acidic wheel
cleaners, especially on spoked
wheels. If such products are
used on hard-to-remove dirt, do
not leave the cleaner on the
affected area any longer than
instructed. Also, thoroughly
rinse the area off with water,
immediately dry it, and then
apply a corrosion protection
spray.
•Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use
only a soft, clean cloth or
sponge with mild detergent and
water to clean plastic.
