Recognise tyres handling difficulties

It isn't always easy to get to the bottom of the reasons for different performance issues. Performance issues may be caused by the tyres (type of tyre, incorrect pressure…) and/or a change to the vehicle (accessories, load…). Tyres aren't always the only element to consider.

Vibrations

These occur throughout the whole front fork/wheel usually at speeds of around 90 to 130 km/h (55 to 80 mph).

Tyres are not always the only issue

Weight distribution has a significant impact on whether or not a vehicle will develop a problem. The addition of accessories or modifications (non original top boxes, bags, fairings, windscreen, handles, seat, wheels...) may also play a part in performance.
