The Honda CBR250R ignition system consists of power unit, ignition coil, battery, ignition switch, spark plug and pulse rotor. The Honda CBR250R has a digital unit with a built-in micro computer provides best ignition throughout its operating speed range. A pulse has seven projections. From (1) to (7) have 45 degree separation and 90 degree for (7) to (1). By detecting the time required to have the projection at the pulser coil again, the engine rpm is determined and the micro computer determines ignition timing. The following diagram shows detail schematic and wiring diagram of Honda CBR250R Ignition System.
