Good info on the 150r. I got spoiled riding that and want one. But everyone is telling me that I should start with less powered ones and hone in technique at the mini go kart track.
The 150r is the less powerful one to start on. Most proper adult size bikes are 125 2t and 250 4t. the 150r is a kids bike. Were only talking ~25hp here. The thing you want is the proper suspension that comes with the 150r, that will make the difference. Unless you can get one (100, 150f, 230f) that has been converted, its just a toy.
