will an aprilia rs50 mess up my skill

I have a two stroke RM 250 for track and trails, and an Aprilia Shiver 750 for street.

The Shiver feels a lot like a dirt bike, as far as rider position and power to weight ratio.

No need to be afraid of the Shiver, either; it has three engine mapping programs to choose from.

The "rain" setting cuts horsepower by 25%, the "touring" setting smoothes out throttle response, and "sport" is a real kick in the ass.

This is the first street bike I've ever owned and I haven't had any scary moments (except for the occasional, but inevitable, idiot in a car that drives around with blinders on).

The little 50cc will probably have you wishing you'd gotten a real bike pretty quickly.

Test ride one of these, before you buy anything:

i have two aprilia rs 125 and one suzuki rgv 250, when the weather allow it i use an aprilia for school-home travel and sometimes i put on my leather suit and i go with my friends in some mountain pass. After all the week on the street bike the first minute on the dirtbike at the track feel kinda strange but it's temporary, don't worry and if you can get something bigger than a 50cc just do it.
