GP-1 is a motorcycle racing game from Genki and published by Atlus in the US, Japan and Europe. It takes a behind-the-bike perspective established by Sega's Hang-On, enhanced by the Super Nintendo's Mode 7.
The player can choose their bike, configure the bike's parts and even choose their own mechanic from a limited selection. The player wins money in races that can be spent on improving their bike.
The game was followed up with a sequel, GP-1: Part II.
Electronic Gaming Monthly's Mike Weigand gave GP-1 a review score of 7 out of 10. He wrote, "...This is another behind the vehicle perspective racing game except it's more like Road Rash -- you ride a motorcycle (but there is none of the side-by-side brutal fighting). Getting used to your racer takes some time, but overall it is a good racing game".
