What is the purpose of rextor C.D.I. for suzuki raider r150?

Racing CDI is an upgrade to most underbone bikes. It is used to replace the stock cdi. The stock cdi is programmed to have an RPM (revs per Minute) limiter to prevent the rpm to go up so high that it may cause damage to your engine. Or so since the peak horse power of some underbone bikes are in the range of 9-10k RPM, the limter activates when the RPM soars above 10k. Racing CDI on the other hand is designed to remove the RPM limiter of most motorcycles. It has a built in adjuster to adjust the ignition timing of your motorcycle.
