Tyre services

At every CRT track day, multi-brand tire services are available on the paddock. They give advice on tire pressures and can change tires. The tire services have almost only racing tires in stock, not street tires. Participants who come to the circuit on their motorcycle ensure that the number of millimeters of profile when riding home at least meets the legal standard.

Technical support

The participant is solely responsible for the perfect technical condition of his motorcycle. If there are technical difficulties during the CRT trackday the CRT participant can contact Edwin Ott Motorbikes in pitbox 8, which is specializes in Yamaha bikes and at the trailer of RR Motorsports which is specializes in BMW bikes. Both specialists also control the technical background of all other brands bikes


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.

Motorbike clothing

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:

Dynamic noise limit 101 dBa

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.

Onboard cameras

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.
