It is the sound pressure escaping directly from the exhaust that cause this chamber to resonate. This resonance chamber acts like a mechanical amplifier. It is the cause of the roaring sound that is perceived as annoying and unpleasant, which can have an effect on physical sensitivity by causing subjective stress and unease, thus distracting from events on the road.

Our GONZZOO exhaust deflector, with a high-quality, black heat-resistant and durable ceramic coating, diverts the exhaust flow away from this resonance chamber and deflects the acoustic pressure from the sides upwards. This noticeably reduces the irritating drone and the effects mentioned.

The performance-influencing dynamic pressure doesn’t change, so there’s no loss of performance!

Passengers find the GS to be subjectively quieter since the acoustic pressure is shielded on the sides.

The deflector shields the heat radiation of the exhaust stream so that the heating of the cases and the case contents are noticeably reduced.

Mounting is easy thanks to the spring supports, so the compact deflector can be fitted and removed any time. The matching tool is supplied with the delivery. With German type approval.

Is there a connection between noise minimisation and ergonomics?

On subjective perception and its potential effects on riding safety
Nothing should irritate you while riding and thereby distract you from pleasurable riding and events on the road. We offer a massive range of ergonomic components that specifically follow this approach. They allow you to adjust your motorcycle so that nothing irritates or disturbs you any more and you can enjoy riding, but also so that you can determine the traffic situation up ahead, because all human-machine interfaces are optimally adjusted. Ergonomics thus not only creates a win for comfort and riding pleasure, but rather – and actually just as relevant – extra safety while riding.

What normally applies for a non-ergonomic motorcycle in the conventional sense can also be applied analogously to noise emissions. In addition to their purely objective impact, noise emissions can also cause subjectively perceived negative impacts on wellbeing that irritate and disrupt while riding, meaning that the rider can no longer concentrate 100% on riding and events on the road. So if you reduce noise emissions and their subjectively perceived negative impacts on wellbeing, you also gain a bonus to riding safety, and above all, riding pleasure.The facts
