Foreword
NOTE
CARRY OUT MAINTENANCE OPERATIONS AT HALF THE INTERVALS SPECI-
FIED IF THE VEHICLE IS USED IN PARTICULAR RAINY OR DUSTY CONDI-
TIONS, OFF ROAD.
Motorcycle care
Aprilia recommends using quality products for cleaning the vehicle. The use of un-
suitable products can damage vehicle components. For cleaning do not use solvents
such as "nitro thinner", "cold cleaning agents", fuels or the like, or cleaning products
that contain alcohol.
WASHING THE MOTORCYCLE
Aprilia recommends softening with plenty water and then carefully removing insects
and stubborn stains before washing the vehicle.
To prevent stains, do not wash the motorcycle immediately after exposure to sunlight,
and do not wash it in the sun.
If the vehicle is used during the winter months, be sure to frequently wash the motor-
cycle. To remove anti-icing salt sprayed on roads in the winter, wash the motorcycle
with cold water immediately after use.
CAUTION
AFTER CLEANING YOUR MOTORCYCLE, THE EFFICIENCY OF THE BRAKING
SYSTEM MAY BE TEMPORARILY AFFECTED DUE TO THE PRESENCE OF WA-
TER ON THE FRICTION SURFACES. CONSIDER AN INCREASE IN BRAKING
SPACE, OPERATE THE BRAKES REPEATEDLY TO RESTORE NORMAL CON-
DITIONS. CARRY OUT THE PRE-RIDE CHECKS BEFORE USE.
8
1 General rules

USE OF HOT WATER INTENSIFIES THE EFFECT OF THE SALT. USE ONLY
PLENTY OF COLD WATER TO WASH AND REMOVE ANTI-ICING SALT
USE OF HIGH PRESSURE WASHING SYSTEMS (OR STEAM CLEANERS) CAN
DAMAGE THE SEALS, OIL SEALS, BRAKING SYSTEM, ELECTRICAL SYSTEM
AND THE SADDLE. DO NOT USE STEAM OR HIGH PRESSURE CLEANING SYS-
TEMS. DO NOT USE STEAM OR HIGH PRESSURE CLEANING SYSTEMS.
CLEANING OF SENSITIVE PARTS
BODYWORK
To keep the motorcycle bright, wash it regularly, especially if used in areas with high
levels of pollution or mud. Stubborn stains of tree resin, petrol, oil, brake liquid or bird
droppings should be removed immediately, otherwise the stains risk becoming per-
manent.
After washing it is easy to identify marks and residual stains, remove them from the
body using a soft cloth and brand-name, non-abrasive polish, and protect with a pro-
tective wax for cars. Periodic care, a thorough cleaning and regular protective wax for
the bodywork preserves the aesthetic quality of the motorcycle over the long term.
PLASTIC COMPONENTS
IF THE PLASTIC COMPONENTS ARE CLEANED USING AGGRESSIVE AGENTS,
THE SURFACE MAY BE DAMAGED. DO NOT USE CLEANING PRODUCTS CON-

TECT THEM WITH WAXES OR SUITABLE ACID-FREE PRODUCTS (E.G.
VASELINE)
RADIATOR
IF THE VEHICLE IS USED IN WINTER ON ROADS TREATED WITH SALT, WASH
THE RADIATOR FREQUENTLY TO PREVENT COSMETIC DAMAGE TO THE FIN-
ISH AND THE RISK OF ENGINE OVERHEATING. WASH WITH PLENTY OF
WATER. WASH WITH A LOW PRESSURE JET OF WATER, USING A GARDEN
HOSE FOR EXAMPLE.

that you do so in an open or very well ventilated area. Never run the engine in an
enclosed area. If you do work in an enclosed area, make sure to use a fume extraction
system.
CAUTION

Fuel
CAUTION
FUEL USED TO DRIVE EXPLOSION ENGINES IS HIGHLY INFLAMMABLE AND
CAN BECOME EXPLOSIVE UNDER SPECIFIC CONDITIONS. IT IS THEREFORE
RECOMMENDED TO CARRY OUT REFUELLING AND MAINTENANCE PROCE-
DURES IN A VENTILATED AREA WITH THE ENGINE SWITCHED OFF. DO NOT
SMOKE DURING REFUELLING OR NEAR FUEL VAPOUR. AVOID ANY CON-
TACT WITH NAKED FLAME, SPARKS OR OTHER HEAT SOURCES WHICH MAY
CAUSE IGNITION OR EXPLOSION.
DO NOT ALLOW FUEL TO DISPERSE INTO THE ENVIRONMENT.
KEEP OUT OF THE REACH OF CHILDREN.
IF THE VEHICLE FALLS OR IS ON A STEEP INCLINE FUEL CAN LEAK.

AND PROTECTIVE APPAREL. IN THE EVENT OF SKIN CONTACT WITH THE
ELECTROLYTIC FLUID, RINSE WELL WITH PLENTY OF CLEAN WATER. IT IS
PARTICULARLY IMPORTANT TO PROTECT YOUR EYES BECAUSE EVEN TINY
AMOUNTS OF BATTERY ACID MAY CAUSE BLINDNESS. IF THE FLUID GETS
IN CONTACT WITH YOUR EYES, WASH WITH ABUNDANT WATER FOR FIF-
TEEN MINUTES AND CONSULT AN EYE SPECIALIST IMMEDIATELY. THE BAT-
TERY RELEASES EXPLOSIVE GASES; KEEP IT AWAY FROM FLAMES,
SPARKS,CIGARETTES OR ANY OTHERHEATSOURCES. ENSURE ADEQUATE
