Noise limits and technical check

Noise limits differ by circuit. The limit for your day is stated with the trackday. Read it in advance, even if you have ridden the same bike elsewhere before.

Original exhausts are allowed. A modified exhaust must always have a dB killer. Check beforehand that it is fitted securely.

An original exhaust or a fitted dB killer does not automatically mean your bike meets every noise limit. The circuit's limit still applies.

Report to check-in first. There you receive your rider number and transponder sticker. Then take your bike to technical inspection.

Wear a helmet when riding in the paddock, even if you are only going to inspection.

Inspection looks at the brakes, tyres, leaks and the general technical condition of your bike, among other things. Arrive with a bike ready to ride; inspection is not a maintenance service.

If something is not right, discuss what is needed before you can go on track with the inspection team. For technical help, contact the tyre service; what they can do depends on the work and time available.

If you ride several days within the same event, you only need to check in and have your bike inspected once.

You remain responsible for checking that your bike is in order. Between sessions, check tyres, fuel and any leaks or loose parts.

Have you fallen? Your bike must pass technical inspection again before you may return to the circuit, even if the damage looks minor. Report to the team for reinspection.

If you receive a black flag because your bike makes too much noise, follow the directions and leave the track. You receive a warning and an opportunity to adjust your bike. You may then go back on track.

Your bike must still meet the applicable noise limit. A warning does not allow you to keep riding an unchanged bike that is too loud. Talk to the team if you are unsure whether an adjustment is enough.
