Hierbij mijn vraag die ik ook stelde op het Aprilia forum. Antwoord gerust in het Nederlands.
Hi, I bought an used 2011 RS4 50 with almost 17000 km on the clock, and I checked the exhaust and the restriction there has been removed (in the first section where the pipe connects to the engine), all the rest of the bike is stock. It seems that it has been dropped a couple of times but the bike is mechanicly fine. Problem is, it maxes out at 75 km/h DOWNHILL and accelerates quite slow (1st and second gear are useless as well). It revs up to 11.5k RPM. Can somebody help me and give me some advice on how I can make this thing faster please?
Bedankt
