Over the past 4 years, stories have risen about a future motogp and possible wsk from BMW. Photoshops, concepts, prototypes, all talk but nothing concrete. Here are some pics of different bikes seen around. I think the issue is the position of BMW's boxer setup. If they were to try a more coventional v2 or i4, they would be able to build a bike that can knee drag without scraping the head off!
HP2 Sport (still a boxer~obviously)
You can see this bike has either a conventional setup or the boxer that is horizontally opposed (less likely)
Test mule from a while back!
