As tyre pressure is affected by temperature and altitude
variations, you are advised to check and adjust it whenever
you are riding in areas where ample variations in
temperature or altitude occur.
Important
Check and set tyre pressure when tyres are cold.
To avoid front wheel rim distortion, when riding on bumpy
roads, increase front tyre pressure by 0.2 - 0.3 bar.
Tyre repair or replacement
In the event of a tiny puncture, tubeless tyres will take a
long time to deflate, as they tend to keep air inside. If you
find low pressure on one tyre, check the tyre for
punctures.

Warning
A tyre must be replaced when punctured.
Replace tyres with recommended standard tyres only.
Be sure to tighten the valve caps securely to avoid leaks
when riding. Never use tube type tyres. Failure to heed
this warning may lead to sudden tyre bursting and to
serious danger to rider and passenger.
After replacing a tyre, the wheel must be balanced.
Important
Do not remove or shift the wheel balancing weights.
Warning (ST4s ABS)
Have the tyres replaced at a Dealer or Authorised
Workshop. Correct removal and installation of the wheels
is essential, as some parts of the ABS (such as sensors
and phonic wheels) are mounted to the wheels and require
specific adjustment.
