safe drive

BASIC SAFETY RULES

To drive the vehicle it is necessary to be in possession of all the requirements pre­scribed by law (driving licence, minimum age, psychophysical ability, insurance, state taxes, vehicle registration, number plate, etc.).
Gradually get to know the vehicle by driv­ing it first in areas with low traffic and/or pri­vate areas.
The use of medicins, alcohol and drugs or psychotropic substances notably increases the risk of accidents. Be sure that you are in good psychophysi­cal conditions and fit for driving and pay particular attention to physical weariness and drowsiness.
Most road accidents are caused by the driver’s lack of experience.
NEVER lend the vehicle to beginners and, in any case, make sure that the driver has all the requirements for driving.

STOP
Rigorously observe all road signs and na­tional and local road regulations. Avoid abrupt movements that can be dan­gerous for yourself and other people (for example: rearing up on the back wheel, speeding, etc.), and give due consideration to the road surface, visibility and other driv­ing conditions.
Avoid obstacles that could damage the ve­hicle or make you lose control.
Avoid riding in the slipstream created by preceding vehicles in order to increase your speed.
Always drive with both hands on the han­dlebars and both feet on the footrests (or on the rider’s footboards), in the correct driving posture.
Avoid standing up or stretching your limbs while driving.

The driver should pay attention and avoid distractions caused by people, things and movements (never smoke, eat, drink, read, etc.) while driving.
use and maintenance
8
RS 250
Use only the vehicle’s specific fuels and lu­bricants indicated in the "LUBRICANT CHART"; check the oil, fuel and coolant levels regularly.
If the vehicle has been involved in an acci­dent, make sure that no damage has oc­curred to the control levers, pipes, wires, braking system and vital parts. If necessary, have the vehicle inspected by an aprilia Official Dealer, who should care­fully check the frame, handlebars, suspen­sions, safety parts and all the devices that you cannot check by yourself.
Always remember to report any malfunc­tion to the technicians to help them in their work.
Never use the vehicle when the amount of damage it has suffered endangers your safety.

ONLY ORIGINALS
Never change the position, inclination or colour of: number plate, direction indica­tors, lights and horns.
Any modification of the vehicle and/or the removal of original components can com­promise vehicle performance levels and safety or even make it illegal.
We recommend respecting all regulations and national and local provisions regarding the equipment of the vehicle.
In particular, avoid all modifications that in­crease the vehicle’s performance levels or alter its original characteristics.
Never race with other vehicles. Avoid off-road driving.

CLOTHING

Before starting, always wear a correctly fastened crash helmet. Make sure that it is homologated, in good shape, of the right size and that the visor is clean.
Wear protective clothing, preferably in light and/or reflecting colours. In this way you will make yourself more visible to the other drivers, thus notably reducing the risk of being knocked down, and you will be more protected in case of fall.
This clothing should be very tight-fitting and fastened at the wrists and ankles. Strings, belts and ties should not be hang­ing loose; prevent these and other objects from interfering with driving by getting en­tangled with moving parts or driving mech­anisms.
use and maintenance
RS 250

Do not keep objects that can be dangerous in case of fall, for example pointed objects like keys, pens, glass vials etc. in your pockets (the same recommendations also apply to passengers).

RS 250

ACCESSORIES

The owner of the vehicle is responsible for the choice, installation and use of any ac­cessory. Avoid installing accessories that cover horns or lights or that could impair their functions, limit the suspension stroke and the steering angle, hamper the operation of the controls and reduce the distance from the ground and the angle of inclination in turns. Avoid using accessories that hamper ac­cess to the controls, since this can prolong reaction times during an emergency. Large fairings and windscreens assembled on the vehicle can produce aerodynamic forces capable of compromising the stabili­ty of the vehicle while driving.
Make sure that the equipment is well fas­tened to the vehicle and not dangerous during driving. Do not install electrical de­vices and do not modify those already ex­isting to avoid electrical overloads, be­cause the vehicle could suddenly stop or there could be a dangerous current short­age in the horn and in the lights. aprilia recommends the use of genuine accesso­ries ( aprilia genuine accessories).

LOAD

Be careful and moderate when loading your luggage. Keep any luggage loaded as close as possible to the centre of the vehi­cle and distribute the load uniformly on both sides, in order to reduce imbalance to the minimum. Furthermore, make sure that the load is firmly secured to the vehicle, es­pecially during long trips.
KG!
Avoid hanging bulky, heavy and/or danger­ous objects on the handlebars, mudguards and forks, because the vehicle might re­spond more slowly in turns and its ma­noeuvrability could be unavoidably im­paired.
Do not place bags that are too bulky on the vehicle sides and do not ride with the crash helmet hanging from its string, because it could hit people or obstacles making you lose control of the vehicle.
Do not carry any bag if it is not tightly se­cured to the vehicle.
Do not carry bags which protrude too much from the luggage rack or which cover the lights, horn or indicators.
Do not carry animals or children on the glove compartment or on the luggage rack.
Do not exceed the maximum load allowed for each side-bag.
When the vehicle is overloaded, its stability and its manoeuvrability can be compro­mised.
