All in one: Fantastic sound, great looks, unmatched quality and all legal

For most of us, a pure and unclouded driving experience go hand-in-hand with a matching exhaust sound. Everything here at KessTecch is focussed on providing the best Sound! Our slogan “Feel the Sound.” highlights this. No other exhaust manufacturer succeeds so well in bringing the exhaust sound so pure and at the same time legal to the streets. Our electronics ensure that the sound system provides the driver with a unique sound experience and that it can be driven totally legal at the same time. These electronics ensure that the exhaust sound complies with the applicable laws.

In short: as an owner of a KessTech adjustable exhaust system you can permanently and legally experience a great sound. You as the driver decide which of the different modes you like to choose, may it be ESM or ESE. With ESE: out of town, following winding roads, towards the sun, freedom pure on two wheels – the perfect environment for the ON mode! Or even longer trips in the MEDIUM mode. In the evening heading back towards home, back into town, into your residential district – now totally ESE switching towards OFF mode and your neighbors will welcome you with a smile! With KessTech you can adapt your sound to your environment and have fun that way. You can also drive chilled and smoothly on longer tours or drive through town.

The evolution of KessTech

It all begun with our MMV (manual mechanically adjustable sound system). The MMV can be opened and closed within seconds with a simple tool. In the closed version the MMV systems has an EC type approval. After the MMV we developed our first exhaust system with electronics: the first generation of our Electronic Sound Management Systems (ESM1) was born which enables the rider to activate or deactivate the sound management at the touch of a button. With the introduction of ESM2 and ESM3 we were able to continually optimize sound and performance. In 2017 the exhaust industry was brought to a new era. ESE is not just an upgrade but a completely redesigned system that redefines the unique driving experience and provides the unmistakable exhaust sound you have come to expect from KessTech once again. Today we are “state of art” with ESE: no other manufacturer unites sound, quality and operating comfort in such a convenient package like KessTech does. A successful market introduction reflects trade press, dealers and customer’s appreciation of our exhaust system.

What is ESE?
ESE is based on the idea and the ambition to bring the biker's driving experience with an unique sound to perfection. ESE provides features that have been asked for a long time but also completely new features. For example, in addition to the OFF and ON modes, ESE is equipped with a third mode MEDIUM, in which the exhaust valve takes on an intermediate position and provides the rider with an additional, third, cleary distinguishable sound option. Additionall, there is a novelty - the Power-Feature: in the OFF mode, an additional burst of power is available if the rider demands it. ESE automatically detects when a rider suddenly requires more power (for example while overtaking or in a dangerous situation that requires immediate power) and delivers the additional power without that the rider has to change the mode. Furthermore, in the OFF mode, the same peak power is available as in the ON mode. Your driving adventures will be great fun because of the different sound modes and faster response of the new motors!

Everything ESE!
The interaction with the ESE system is intuitive – totally ESE. Regardless of the complex technology. When the motorcycle is switched on, ESE is by design in OFF mode, the button does not light up in this mode. If the button is pressed once, ESE switches to ON mode, the button lights up blue. Pressing a second time switches ESE to the MEDIUM mode, the button now lights up green. If the button is pressed a third time, ESE switches back to OFF.

OFF Mode

Whenever you feel like, you can drive quietly, in a residential zone, passing by the city park or when arriving home late – everbody will love you!

ON Mode

Whenever you as driver feel like enjoying the full sound, you can drive in the activated mode, when on a country side road, driving thru hills and valleys or passing by your city café – you will love it!


Whenever you like, you can also try the MEDIUM mode – by using MEDIUM you are able to enjoy longer trips much more relaxed or while having your buddy on the bike – not only you, but your partner will love it!
