How the SP Electronic quickshifter works
The electronic quickshifter is one of the most appreciated technologies in the racing world. It allows extremely fast gear changes without using the clutch and without closing the throttle, improving track performance and making sport riding smoother. In this article we explain how the SP electronic quickshifter works, designed for motorcyclists who want maximum performance, reliability and ease of installation.
What is an electronic quickshifter?
An electronic quickshifter is a system that detects movement of the shift pedal and sends a signal to a control unit, which briefly interrupts ignition or fuel injection for a few milliseconds. This short interruption unloads the gearbox just long enough to complete the gear change without engine load. The result is very fast and precise shifts, even under full acceleration.
Why choose the SP quickshifter?
SP systems are designed to offer:
Reliability even in extreme conditions, such as racing or off-road use
Wide compatibility with carbureted and fuel-injected motorcycles
Plug and play configuration, with dedicated wiring for each model
Robust and mechanically precise sensors, developed in Italy
Each kit includes:
An electronic sensor, available in push, pull or bidirectional versions
Wiring compatible with original or aftermarket ECUs
A control unit for motorcycles without factory quickshifter support
Installation instructions and technical support in Italian
How it works in practice
The sensor detects movement of the pedal, either pressure or pull
In a few milliseconds, the control unit temporarily cuts ignition or injection
The gear change happens without closing the throttle and without using the clutch
Power returns immediately after the shift
All of this happens in 20 to 60 milliseconds, imperceptible to the rider but crucial for lap speed.
Who can install it?
Our kits are ideal for both professionals and enthusiasts. Installation is simple and reversible, and does not require permanent modifications to the motorcycle.
Thanks to specific wiring for brands such as Honda, Yamaha, Suzuki, Kawasaki, Ducati, Husqvarna, TM and many others, you can install your SP quickshifter at home in your own garage, or rely on a trusted mechanic.
