I've been fascinated with two-smokes since the Indy GP, but parts and maintenance concern me. I also wonder how well a 125 would haul my 200-lbs lard ass.
I saw a guy on the 1st or 2nd at NJMSP riding one of these and i remember saying to myself i should not eat for a year just so i could ride one of those things, they are really cool!!
Actually, I looked at those. Spoke to Ozzy a few times about minigp, seems like nice chap. But the bikes are complete and utter crap compared to the RS125. Not to mention that you're going to spend just as much for a Metrakit GP125 bike!
The Aprilia 125 sold here in the US has all of the lights and other electrics required by the DMV. However, the wiring harness disables those features so that people will not be 'tempted' to sneak one by. An EU wiring harness can easily be bought if your DMV can be snookered... There are plenty of Aprilia RS 250's on the road so it is indeed possible....
The RS125 as a street bike is a huge global seller for Aprilia and it's build quality and reliability are impressive!
