The game has a heavy carboard count as there is a huge selection of track pieces that allow you to construct a wide variety of tracks. It also comes with some very nice Bike models and player dash boards which have various dials on used for the more advanced rules.
I have to say from the basic game, to the more advanced rules it feels like a bike race and you do have to make choices on when/where to accelerate/brake and its just feels right. There are expert rules which bring in things like slipstreaming, up/down hill effects etc.
There is a lot of replayability here what with the various versions of rules to play by, the modular track and the unique dice mechanic. You have the option to "flip" your dice (what dice and how many is determined by where you are on the track) this helps reduce a lot of the luck element and enables you some degree of control of how to position your bike. In the advanced rules you can use braking or engine points to affect your movement which helps add to the realism of the game.
I really liked this game, being a non-biker, and I would definitely play this again.
