When I rode an unrestricted S1000RR, I'll tell ya, I fell in love with the thing. It is absolutely the most brutal bike I have ever been on in my life. It flicks around like a 600cc, other than the wheelie control (which, thank God for that the first time I got on it), it has no real sense of restricting its own power. It was by a long, long shot, purely a race bike with number plates on it. I will end up purchasing one. By far and a long way one of the most magnificent machines I've ever had the pleasure of being on.
