MotoTrainer was developed in partnership with Dorna -- aka the company that owns MotoGP -- and works either with the game MotoGP or riders can follow an onboard lap of any of the MotoGP circuits.
Unfortunately, there currently aren't any hardcore motorcycle racing simulations in the vein of iRacing available to the public, so don't expect to have the same experience. .
Well, maybe you're a hardcore motorcycle racing fiend that is unable to get to a racetrack with a bike, or possibly you're someone recovering from a prior injury.
