The KORTECHS KS-1 quickshifter for gearbox karting


You are always wondering why you have to get off the gas pedal when you want to shift a gear? WE TOO...!


The KORTECHS KS-1 quickshifter is a mecatronic system allowing for the kartings equipped with a gearbox to shift up a gear without getting off the foot from the gas pedal. Shift during full throttle! 


This has been specially developed to meet the specific demands in karting.


For who?

The KORTECHS KS-1 quickshifter is made for recreational pilots looking for sensational driving experience without difficulties and without stress. The driving of a gearbox karting will be much more easier. 


The competitors will benefit of a very fast gear shifting just impossible to achieve without the KORTECHS  KS-1 quickshifter. The stop watch will turn crazy in the KZ1 class !

How it works

To shift up a gear, you just have to pull on the original lever during full throttle.

During a very short period (setable from 25 to 50 ms), the system will cut off the engine ignition decreasing a short instant the traction force on the gearbox and allows you to shift a gear up.

To have an idea of how fast is the system, you have to know that a supercar is able to shift up a gear in 100 ms...!


The cut off time is setable by mean of a selection button. This enables you to optimaly set the quickshifter to the specification of your gearbox (type of engine, new or old engine) and the track (wide and fast or narrow with pin heads)

The activation force and sensivity are also ajustable.
