The mod features faster AI and different player bike physics.
The player will have the same bike physics (per DATA mod) regardless of what MotoGP team/bike they'll ride (so there shouldn't be any difference if you ride an ART or a factory Yamaha/Honda).
The AI bike physics are the same for all the DATA files.
1DATA.MIX - fastest player bike*
4DATA.MIX - slowest player bike*
*identical for all teams/bike models
Installation: extract the archive / backup your current DATA.MIX (e.g. rename it to "0DATA.MIX"), and then rename one of the modes to DATA.MIX
