Better Be Rich Motorsports always comes up with something new ..... you'd be nuts in the head to buy one for anything other than competition class racing where you're limited to a horizontal engine .......

A smarter person would buy a CRF150R (dry sump vertical engine) which would be faster at less than half the price for an entire bike .........
