If you wish to do maintenance tasks to your Aprilia RXV450 then it is usually a good idea to have access to a Workshop Manual for reference if you need to know how you can strip off a certain component for example the Brake Discs and install it again safely.
Aprilia RXV450 Workshop Manuals provide you with identifiable diagnostic details for the automobile so if something is wrong it helps you understand what the issue is and tips on how to resolve it. You can then decide if this can be achieved yourself or in case the job is too big you can still make a booking for your RXV450 into a decent garage.
