Please note - for Bike Testing noise regulations please CLICK HERE

These days, all racing circuits have noise restrictions and at MotorSport Vision we are unfortunately no exception. It is extremely important that we operate in compliance with our limits so that we also minimise any disturbance to local communities.

Noise can travel a long way, particularly in certain climatic conditions and therefore we must act in accordance with the regulations to ensure the future of trackdays for everyone that abides by the rules. Please help us by making your bike as quiet as possible before taking part in any on circuit activity.

Although the requirements below may seem restrictive, they ensure that the majority of trackday customers who do not attempt to flaunt the noise limits are able to continue to enjoy their events without jeopardising future trackdays with further restrictions.

Anyone wishing to have their bike tested before a trackday is more than welcome to come to one of our circuits and have a noise test free of charge. Simply find a day at your most local track when an event is taking place (all events are listed on our Trackday Calendar) and arrive sometime between the start and finish times of the event and we can get your bike tested in just a couple of minutes.

The initial test is a static test which is carried out using a handheld meter. Each bike is measured 0.5 meters away from the exhaust at a 45 degree angle when the engine is being held at the following RPM:

In cases where the motorcycle has two separated exhausts the measurement will be taken as above from the median point between the two.

For bike trackdays, the noise regulations for each of the circuits are as follows: 

If you are unsure about the times that we are running noise testing then you can contact each circuit directly on the phone numbers above.

Drive by monitoring

If the results of the drive-by monitoring show that your vehicle is generating drive-by sound levels appreciably higher than vehicles with comparable static test results, then you will be called into the pit-lane to address the noise level being generated.

Additional Information

Factors such as air temperature and humidity can affect the level of noise that your bike is producing. This means that whilst on one day your bike is within the respective limits, on another it may fall outside of those limits, preventing you from participating.

For your own piece of mind we urge you to keep a record of your bikes noise level at each event. If you are ever within 1dB(A) of  a particular limit then we suggest that you strongly consider having your exhaust looked at before making another booking.

Exhausts do get louder with age as the packing deteriorates and it may be that you need to purchase an additional silencer or baffle before attending another event.
