For ultra-fast and gear-saving gear changes.

Driving without semi-automatic gearshifting, ie upshifting with gas take-off and clutching, is now almost unimaginable for the vast majority of our satisfied customers. 


 

The functional principle of a switch (semi) automaton can be described in a simplified way as follows:
The movement of the gear lever when upshifting with a sequential gearbox, is automatically (!) Coupled with a removal of the load (= engine power). As a result, a completely "powerless" gear change can be realized without gas take-off and without clutch actuation. As soon as the gear is changed, the load (= engine) is automatically switched on again.

Sounds relatively simple, a "side effects" interruption of the ignition, however, requires some effort.
We started with the development of automatic switching machines at the beginning of the 90s. Our MQS models have achieved countless successes in racing.
Before purchasing a switch, be sure to check the device carefully. On our pages you will also find the answer Why KLS? Can offer you a highly professional solution.

Why an automatic switch?

10 reasons for using a switchgear.
  • Upshifting without gas or clutch actuation
  • Extremely fast gear changes
  • No disturbing movements on the handlebars with chassis turmoil and loss of speed
  • Higher comfort and increased safety through full focus on driving
  • No interruption of the gas oscillations in the intake and exhaust tracts.
  • Implementation of the rotational energy of the crankshaft when switching to additional acceleration due to extremely short switching times
  • Full power of the engine after the gear change
  • clear lap time improvement
  • Significantly more driving pleasure

technical description

The KLS automatic switchgear has been technically designed for the highest quality, with maximum operational safety and was designed for the simplest installation, operation and adjustment.

The components of the MQS automatic switch

The electronics box processes the signals of the sensor box and electronically interrupts the ignition of the engine. The induced in uncontrolled ignition, but unwanted and harmful misfires are completely avoided electronically. In case of unintentional interruption, the ignition (after approx. 80 millisec.) Is automatically switched back on, so that an unintentional shift lever movement or ignition interruption does not lead to a reduction of the driving speed during the journey. However, this function is also absolutely necessary, so that can be switched in the state of the first gear in the idle, without the engine stops.

The high-speed SENSORBOX is stable and insensitive to vibration and synchronizes the respective gear mechanism with the electronics of the automatic switch. It is designed for shortest switching times and has two inductive, absolutely dirt and water-insensitive sensors for highest possible operational safety, switching accuracy and switching speed. One sensor for the beginning, the second sensor for the end of the ignition interruption

With the MQS automatic switch, the LEDs are red / green for the exact adjustment of the "STOP" or "RESTART" switching points of the red "MQS" sensor box and enables their exact matching to the respective gearbox. The control takes place via the gearshift shaft of the sensor box coupled to the gearshift shaft. Both switching points can be adjusted on the vehicle without disassembly of the sensor box each infinitely adjustable by means of adjusting screws and the LED's. This means that the faster the shift lever is actuated, the shorter the ignition interruption: the prerequisite for precise and fast shifting! The sensor box also ensures that the ignition is interrupted only when shifting up the gearbox.
With the ON / OFF switch, the device can be quickly switched on or off manually (eg in the event of a problem) while driving. When switching off the device, the previously interrupted ignition cables are automatically bridged again. Any negative effect of a possible technical problem on the engine ignition can thus be absolutely excluded! Until the problem is then again when switching "conventional" gas and clutch operation necessary. The connection cable to the electronics box is equipped with a reverse polarity protected, waterproof special plug. From this connector, a two-pole cable for the 12V power supply of the electronic box is led out in parallel.

Consisting of 15 super bright LEDs with low power consumption but enormous luminosity. The signal is thus perceived from the corner of the eye, so that the attention of the driver is not affected. Available in yellow or red. Absolutely insensitive to vibrations and wetness. Easy installation in the field of vision of the driver.

(just LSL Version) With reverse polarity protected, waterproof special plug for connecting the LED spotlight to the electronics box.
The small parts required for the electrical connection and a 2mm Allen key for the adjustment of the sensor box are included in delivery.

Assembly

The installation of the MQS is possible with the attached detailed installation and operating instructions quickly, easily and without special knowledge. There are thus no additional costs or complex conversions.

All necessary elements and add-on parts are included in the scope of delivery except for vehicle-specific retaining plates for the sensor box.

The necessary simple mounting brackets for the sensor box can be sawed and filed by any "average" talented screwdriver. In the picture on the right, you can see how easy these parts usually look with the help of some installation examples.

Mechanically: 

The sensor box is fastened to the engine or vehicle frame at a suitable point via the bracket and rubber compensation element, see right. It is controlled by an additional lever mounted on the transmission selector shaft. A complex conversion of the shift lever is not required!

 

electrical: 

With reverse polarity-proof, waterproof special plugs, the components "electronics box", "sensor box" and "ON / OFF switch" are interconnected.

The electrical connection is made to the on-board battery, the 12V supply of the CDI or, if necessary, to a separate 12V battery.

The connection to the ignition coil (s) is ensured by contact-safe flat connectors.

The adjustment of the MQS is just as easy and described in detail and easy to understand in the enclosed instructions.
