Thumpstar BSF Pro 125

About

This is our top of the line race bike for the 10 inch class. It powered its way to fourth in the 2005 AMA National Pit bike series piloted by Mike Leavitt even though it only competed in three of the rounds. If you want to be competitive then look no further. It comes with our Omicron fully adjustable open oil cartridge front fork and Elka Miniseries rear shock plus all the other goodies as normal. This thing is ready to rumble right out of the box and it’s built in the US.
