These are Gobert's qualifying times recently at road america for superstock and supersport.
I know neither are stock bikes, but the difference is clear why you get an R1 over a R6. It would cost a lot of money to take one second off of a quarter mile time, and it would take even more cash to take 4 seconds off a lap time (using the example above). So 3-4K extra is worth it if you are going to use the power. I would agree that an R6 can suffice and is just as much fun.
