[I]I've read that under seat exhausts become uncomfortable for long rides, as in the case of Ducatis - they heat up your **** and your ankles ...
The magazine's words for the review of the CBR600 was "dont go for its looks, its more fashion than purpose..."
But they were professional riders who write for the magazine as they're day-jobs and are track racers when off duty, so their decision might be biased to some extent for the R1
But its a fact, Yamaha and Suzuki GSXR series of sport bikes are way better in quality and performance compared to Honda Sportbikes. Only one model of Honda is worth buying, the 1000cc Fireblade. Otherwise just go for a Yamaha or a Suzuki GSXR.
The Suzuki GSXR750 is a good choice because the GSXR600 is a bit "under powered"
But since you have a choice between the CBR and the R6 .. just go for the R6 man! lol
