The values obtained according to this method are not intended for use as levels of performance or quality. This International Standard is applicable to all motorcycle and moped tyres designed and intended for use on the road. NOTE Since most speedometers and odometers on motorcycles are activated from the front wheel, the test tyres will largely fall into sizes applicable for front wheel use. However, it is accepted that rear tyres will also be measured. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of
