i really like the demo so far, considering its early stage.
For the ones who are disturbed by the upright view, it helped me alot when i turned up the tilt slider in settings/simulation, so that the view gets tilted, gives a much better feel of what the bike is doing.
I still need much improvement in speed though (i never rode a bike for real), my best time so far is a 56.5 with a dual analogue-stick gamepad (basically like a PS2-Controller).
