Kesstech exhaust in detail

ESE (Electronic Sound Experience)

ESE (Electronic Sound Experience) enables the biker an unique driving experience with Full-Volume Sound. In addition to the OFF and ON mode, 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 are two market innovations – the Power-Feature and the Active Engine Protection: 

ESE provides you with power, if you require it! In the OFF and the MEDIUM mode, an additional burst of power is available. 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.

Active Engine Protection
When you are in OFF mode and ESE detects that the vehicle engine is getting hotter and hotter, for example at a red light, the valve opens automatically a little bit in order to reduce the exhaust gas back pressure and to let the heat go out. If the driving profile changes to a thermally more uncritical situation, you will change to OFF mode again.

ESE Software Upgrade at no cost
We are coming up with something new again and again. Therefore, all ESE systems will always receive future software upgrades at no cost! For this, the electronic has to be sent to KessTech and we make sure it is up to date.
