Derbi terra 125 cc,would like to de restrict it but need advice on how

SOURCE: de-restrict an aprilia rs 125

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.,,,

looks like you have a nut at the rear of thr swing arm, one on each side, these are the rear wheel/chain adjusters. slacken the wheel nut and then adjust the nuts, there should be some kind of markings on the swingarm so you can get both sides the same. when done tighten the wheel nut and you are done
