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.

You shouldn't have to restrictions only happen on faster bikes 600cc onwards but if you talking about the inabilty to push your revs to the very max, I wouldn't do this unless you know what you doing, and by you asking this question, you don't know what u doing, this rev restriction is set in place for safety of your engine, rather than restricting speed.,,,

The procedure is not as simple as with the RS50. With the RS50 you buy the bike restricted, which means that it can only go at a maximum of 50 km/h and then after having done some 1000km you have the option to take off the restriction so it can function at its full power (100km/h), which is at the power it was designed to function. I don't know the exact details of this, but it has something to do with taking out a piece that is in the exhaust. The best option is to let an Aprilia dealer do this, as it only costs 100 Euro.
WIth the RS125 the procedure is quite complex and I don't think you should attempt to do it yourself. When you buy an RS125 it is restricted at 15HP, but not because of a simple stop in the exhaust, rather due to the whole configuration of components. The first step is buying the kit that Aprilia supplies for this, which costs around 700 Euro, and then let an Aprilia dealer install it. When you have done that you should have around 30HP (this is model 2006 onwards, the 2005 RS125 had 34HP and earlier models up to 38HP)
