Allumage à rotor interne pour Aprilia : Classic 125 (1995-1999) 125cc MX125 (2004-2006) 125cc RS125 (1996-2005) 125cc RS125 Tuono (2003-2004) 125cc RX125 (1995-2011) 125cc SX125 (2008-2011) 125cc Complete internal rotor ignition kit for various Aprilia including the RS125, see list below. This kit is self-powered, it produces itself, without any other energy source, the power needed for the ignition, however it does not produce the light. The advantage of the internal rotor is its very low inertia, it does not oppose almost any force to the crankshaft which produces accelerations and recoveries well beyond the original ignition. The CDI is delivered with a variable advance curve, which means that it varies to follow the accelerations and give the maximum power at all speeds, for the most demanding drivers it is however possible to take it in programmable in order to be able to adapt the curve to the rest of the engine and to change it according to the track and the desires of each one, more or less advance at the various engine speeds for more recovery or more torque. Options are possible such as 2 curves programmable or not, powerjet, shift system, and throttle management, please contact us. This ignition is perfectly adapted to the competition, it has been tested at more than 20000 rpm without any fault. High quality CEE manufacture, high performance, new, 1 year warranty.
