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 block 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

For participation at a CRT trackday the rider must wear protective leather clothing, or equivalent material, boots, gloves and an approved helmet. The use of a back protector is mandatory. For participants which do not have the proper motor clothing it is possible to rent at the CRT service unit on the paddock a leather motorcycle suit and back protection. Send a mail to Heidi in advance if you want to rent clothing. Heidi mail address:


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. Individual noise measurements no longer take place. 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. The camera must then be connected to the motorcycle with a safety cable. The use of helmet cameras is not allowed.
