Aprilia RS 125 electronic ignition system ( CDI capacitor discharge ignition system )
Consists of :
Generator , alternator - rotor stator
Pick up coil
Regulator
CDI , ecu unit
HT Coil
Spark plug
Buy these parts from here on Ebay UK
Generator , generates the electricity need to run lights and engine , and recharge the battery for starting. See how to test the generator here . is located on the engine.

Pick up coil , This keeps a track on the cranks position , and signals to Ecu for timing of the spark .
see our post here on how to test these , is located on the outside of the Flywheel rotor .

Regulator rectifier , This transforms the 60+ volts AC generated buy the rotor and stator into
14v max DC . is located under the seat fairing panel at rear of bike .

CDI , Ecu computes via internal maps the timing and duration of the spark .

HT coil , generates the spark bolted to oil/coolant bottle , it does
this buy collapsing a 12v coil system , which then transforms 12v to
20,000 volts or so , enough voltage to leap the spark plug gap .
