I'm really impressed with this game. As it's graphics are awesome Many kinds of upgrades can be also done on the bike. If I talk about bikes then there are all bikes except ktm bikes and even and I think that one of your dream bike is also in this like Hayabusa, Ninja H2R, Duccati, 1000 RR, and there is one the fastest bikes in the world also. 110% recomend to download if you like bikes, racing, riding, stunting, and thrill then this game is yours.
