If you wondered why BMW does not build and race a MotoGP bike, Saturday at Motegi gave you your answer. With torrential rain forcing a red flag in the Moto2 Q2 session, the cancellation of MotoGP's untimed practice session FP3 (FP4 had already been scrapped due to the shortened schedule), and the delay of MotoGP Q1 and Q2, Loris Capirossi and his crew were sent out multiple times to assess the state of the track in their safety cars.
That meant that the audience were treated to hour upon hour of BMW cars circulating at speed, with close ups of the cars drifting through the water, the BMW branding on display. (Do not ask me what car it is: I have so little interest in cars I don't even own one. The only thing I know is that it is some form of M model, which, I learned from the introduction of the BMW M1000RR superbike, is BMW's sports brand.)
With this, and the BMW M Award for the best qualifying performances of the year, BMW gets a massive amount of exposure through MotoGP, without the risk of failure associated with actually racing in the series. Why would they trade that in to go racing?
