In Indonesia The development of the world of transportation is very rapid, especially on motorcycles. There are several ignition components in the motorcycle; CDI (Capasitor Discharge Ignition), coil (ignition coil), and spark plugs (spark plug). Fuel ignition system as regulator of process and fuel in cylinder at compression step. At this time do take the results of Torque, Power. Fuel consumption, and sparks between CDI Racing Rextor and CDI Racing BRT-I MAX. Torsion and power retrieval using spontaneous throttel method. This spontaneous throttel stage begins with the engine then to the throttel stabilized at 4000 rpm. After that turn throttel until maximum rotation. The test results are performed in the dynotest to obtain the power and torque results. The results of the research are shown on CDI racing rextor by the highest results compared to standard CDI and CDI Racing BRT, this is because CDI Racing on CDI Racing Rextor is more stable and fast and CDI Standard and CDI Racing BRT. The highest torque is 11.64 (N.m) while the highest power is 15.9 hp.
