Different tools for different jobs...

R6 (or any other superbike) might be quicker and handle better...but 20-30 miles into a rideout and you'll be crying to get off it.

They are designed for 1 thing...the track...people that use them on the road...well...not sure why they are gaining...usually just something to brag about but I doubt they are having as much fun. (usually they spend most of their time scaring the $hit out of themselves!)

A supermoto will kill any sportsbikes in the twisties, which is what its all about...anyone can go quick in a straight line proves nothing.
(Not to mentiion they are a million times more fun!)

Ryan finds his back cannot cope with superbikes, so he's gone for something that doesn't leave him in contant pain but yet is upto the job and keeps him in the game.
