Really awesome.
This racing game reminded me of those N64 racing games.. Great job.. The only suggestion I have is being able to sort of do a "Story Mode", where you can earn cash and upgrade your motorcycle's appearance/Stats(Turning, speed, etc..).. I really loved the levels provided in this free version... Though it might be hard to get people to actually purchase a full version without making it an online racing game, with chat rooms, group races, etc...
