Which is the fastest bike of all?

Is it the Kawasaki H2R? The electric SR/F faster? I'm currently in motorbike driving school and yeah I'll start off with a low CC bike don't worry, but I still would like to know, since I just can't figure it out. Like, the H2R ain't streetlegal unless modified but still, would that sick bike win? Is there a faster bike than these two? via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/ddme3q/which_is_the_fastest_bike_of_all/?utm_source=ifttt
