The law: Rules to follow
All motorcycles are built using the right components for the manufacturer's requirements.
It is important to follow the recommendations of the manufacturer and tyre maker because each motorcycle has its own particular requirements. To avoid breaking the rules of the road, you must stick to a number of basic principles:
- The front and rear measurements specified by the manufacturer
- The performance ratings (load and speed), which must be at least equal to the manufacturer's recommendations
- The same construction (radial or diagonal) to the front and back (except when the manufacturer recommends otherwise).
It is also worth bearing in mind certain common-sense considerations even if they are not strictly part
of the rules of the road
- Fit tyres designed for the same purpose (circuits, sports, touring…)
- Avoid fitting two tyres of different brands as each manufacturer develops its tyres to work together as a pair (front and back). The approved technical specifications therefore E13 differ from one tyre maker to the next. This should only be used as a temporary solution or if you get a flat tyre.
