Rev Limiter / Speed Limiter (remote control) 2-stroke scooters / mopeds

Digital speed limiter module with remote control

Main features

• Digital control of speed and engine rpm, individually or in combination
• Adjustable pre-steps for smooth transitions
• No speed reduction below maximum speed in km/h mode
• No power reduction in the lower rev range in speed mode
• Automatic activation
• Deactivation by remote control
• No-disconnect, no-weld quick-connect cable connectors

Function / Compatibility

The digital speed limiter module with radio remote control and automatic activation is designed for 2-stroke mopeds / scooters. It records current speed and engine speed via an integrated microprocessor. The module works with almost all 2T carburetor engines, such as Minarelli replicas (1E40QMB) like CPI and Keeway. However, it is not compatible with 4-stroke engines, direct injection engines, Morini engines and engines with double pick-up (e.g. Aprilia SR50 with brown and white cables on the CDI).

Speed setting

Speed is read via the supplied sensor (with magnet) on the wheel, while engine speed is measured on the "+" lead of the CDI. The advantage of this digital speed limiter is the ability to adjust the setting with an accuracy of 99.9%.

Operating modes

1. KMH mode:
   • A speed limit is stored in the module. If this limit is reached, the device slows down the scooter by gradually reducing speed.
2. RPM mode:
   • The module stops the scooter when the maximum engine rpm is reached. It does not intervene below this limit, thus avoiding any loss of power.
3. Combined mode:
   • The module operates simultaneously with the set engine speed and the KMH limit. This allows speed and rpm to be controlled at the same time. 

Installation and dimensions

The limiter module is particularly small (45x45x18mm) and fits almost anywhere. The connection cable is 45 to 50 cm long, the wheel sensor is 28x19 mm, and the associated cable is 50 cm long.

Scope of delivery
