When riding on a track, as well as on the road, an optimally adjusted suspension is elementary. During each CRT trackday HK-Suspension gives a theory session about suspension to CRT participants who participate for the first time. During the day the suspension expert in the HK-Suspension pit box adjusts the front and rear suspension of all the CRT participants free of charge.

The participant is responsible for a motorcycle which is in good technical condition and for ensuring that the motorcycle does not produce more noise than is permitted on public roads. The maximum permitted dynamic noise limit is 101 dBA. If the daily average is likely to be exceeded, the riding time of the sessions will be shortened.


The use of onboard cameras is only permitted if it is attached to the motorcycle by means of a support. Camera must then be connected to the motorcycle with a safety cable. The use of helmet cameras is not allowed.
