you can download the shareware there.... i had the full version for awhile
its pretty fun cause you can practice slow wheelies cause there is rear brake and stuff (actually the brake acts as both front and back but it doesnt matter since your front wheel is up in the air) and when you press right or left its makes like the dude is clutching it up :YEAH and stuff like that
The game is obviously not based for stunting so im gonna list a few tracks that has a long straight on it
#11 Gravity Ride (Just turn around and head towards the bottom of the stage) <-- this is the best one just to practice n ****.
#6 Up Hill Battle ( Pretty much straight and declining hills in this stage)
#7 OverHaul ( just go towards the bottom for the straight)

oh yeah you can even save replays incase you do something kewl and just post it up..... we can save the replay into the game folder and watch it from there.

 

IIt is a gay game now that you played it
