EAU01114 PRE-OPERATION CHECKS Owners are personally responsible for their vehicle’s condition. Your motorcycle/scooter’s vital functions can start to deteriorate quickly and unexpectedly, even if it remains unused (for instance, if it is exposed to the elements). Any dam- age, fluid leak or loss of tire pressure could have serious consequences. Therefore, it is very important that, in addition to a thorough visual inspection, you check the following points before each ride.
