No variator spacers in USA models....just game boy the computer to go to test mode....
A aftermarket pipe, some Dr. Pulley sliders, and you should be up to 55 mph, with the 50cc engine.....
A good forum for aprilia's are at AF1 Aprilia forum, with a active sub-forum there......
According to AF1 forum, High Gain Dyno charts, the 2009 model he had to test had the variator spacer. Once removed and flashed with 2.8.0 map it was good for 55mph.
Mine is stuck at 45mph actual. Have some work to do on the variator but I think the rest will stay stock other than a spark plug change.
