SOURCE: de-restrict an aprilia rs 125
Hate to disagree with tina783, but you may have restrictions in place, there is two on the aprilia rs 125. if your on a L plate then the bike should be restricted to 11.5w of power, which is about 15 bhp, when it's de-restricted should be around 34bhp. First is the power valve or a RAVE Valve as some people call it, have you got one? located on the front of the cylinder body, above the exhaust. some times the body of the power valve is there, but there is a blanking plate is underneath it. If the body of the power valve is missing, then its a blanking plate. need to get a power valve and the control unit and the solenoid, fitting is easy look around the net and you'll find one. The next one is the emissions restriction, which is in place due to italy have a real hard on about thier air. The CDI at the back of the back of the bike needs to removed and then if you look at one side you will see a rubber sealant has been used to fill in one side. You need to dig that out and snap a little piece of the circuit board and then refill the hole with a rubber sealant. try to search the net for a how to do on this you need to look at the pics and see what part of the board needs snapping, don't go blindly into this other wise you will kill the CDI. the bike then will act alot more smoothly in the lower end revs.
