You can easily loose your license with a 125cc so the 500 won't help you there if you want the bike to be in control of the speed. To ride fast is not the same as breaking the limit. Here on very twisty narrow mountain roads with drops in 100's of feet with no fencing makes it very hard to hold the limit, you are normally below. As soon as you get through the curve you need power to lift you and the bike upwards in the mountain road. It's awesome because you can have a lot of fun within the law with knee down in the curves and so forth its fun. But it requires power to get the right rollercoaster feeling, a fenomenal bike is the tracer 900 for example.
