The R1 and the R6 are great bikes. There is too much hype involved in 1000cc liter sportbikes, they are not as powerful as the hype has made them out to be. Pick the bike according to what you like the best.. If you ride any of them hard and without any common sense you can get killed in both of them very easily and in very much the same way.
If you like the r1, get the r1. Whats the point of getting a r6 when what you really want is a r1 or a gsxr1000.
