Malossi came up with a complete line of state-of-the-art CDI / ECU units for newer Euro 4 engines (after 2017). The Malossi CDI Unit Digitronic Aprilia SR 50 R Euro 4 is a top quality racing CDI, suitable for powerful cylinders & set-ups.

Optimized ignition curves (variable advance, via 16 break points for rpm and 8 break points for temperature) will considerably improve your scooter's performance. It is small, compact and easy to mount with original fittings.

The rev limiter that is integral to most original ignition units is set to 15,000 rpm, so you can take better advantage of your engine's torque and power.  

SAS valve performance is improved since the Digitronic compensates for non-linear carburetor performance; engine performance is increased, emissions are reduced.
