MPS Electronic Engine Kill

Regular price $177.45

The new generation MPS Air Shifter Electronic Engine Kills have several new features:

  • The kill time can be adjusted from 10ms to 100ms in 10ms increments.
  • Direct Air Valve activation – air valve plugs directly into the kill box
  • Fixed 25ms delay from air valve activation to kill activation.
  • Dedicated Kill Ground direct to the cylinder head.
  • Isolated power circuit.
  • Small Size 4.0” x 2.8” x 1.2”


The new Gen 2 Sport Bike Electronic Engine Kills (1-0263-1) were designed specifically for sequential firing 4 coil ignition systems like those found on most sport bikes today. The Original Electronic Engine Kill (1-0211) was designed in 1987 for drag race bikes (2 coil) to replace the unreliable air kill. The new Gen 2 kill box has a few new features while retaining the robust components proven in our original kill boxes. We have isolated the kill circuit ground. Kill time is set with dip switches under the cover from 10ms to 100ms. The air valve is now controlled by the kill box and has a delay for the kill. This prevents having wasted kill time when there is no air to the shift cylinder. The delay allows the cylinder to pre load before the ignition kill happens. We offer our exclusive, no hassle, free repair or replacement lifetime warranty on the 1-0263-1 kill box just like our older kill boxes. Be sure to ask our competitors about their lifetime warranty. I think you will find they are all less than 6 months if any at all. Custom wiring harnesses with a shifter/horn toggle switch are available as an option for some specific bikes to make wiring your MPS shifter a snap.
