The cbr600 since 2007 is extremely comfortable. I don't think it much different than the triple
a cbr is comfortable by sportbike standards.... but it is night and day to the striple....
-the seat on a street triple is much more comfortable and infinitely more soft
-the riding position is upright compared to the cbr's hunched position (like all ss bikes)
-narrow low clip ons (cbr) vs high wide bars (striple)
-rear sets are lower and farther forward on street triple...
dont get me wrong the cbr may very well be the most comfortable of the ss bikes... but it does not mean its comparable to a bike with upright/ergonomically designed seating position.
i mean.... you might be the fastest runner in your school.... but that doesnt make you THE fastest runner... just in your little group.
i had a street triple, and countless ss bikes. although i did like the street triple, many times more comfortable than any sportbike i rode. had a lot of kick to it(although it is geared differently than the daytona) i found myself back on a ss(daytona675) within a year.
that being said, wind didnt really bother me much in terms of fatigue... ear plugs were helpful as riding was a bit more noisy. i had hte fly screen on there, not sure if it actually helped any or if it was cosmetic only... but it did look good.
either way, if you're looking for a commuter you cant go wrong with a street triple. if you get an ss.... spending everyday with a backpack on your back rolling through traffic in the downtown core... you'd essentially be looking for the most comfortable bike in the group of the most uncomfortable bikes. none will really fit the bill, but if you dont mind sacrificing the comfort, then go for it(i did), but dont kid yourself into thinking you're getting one that will be comfortable in traffic.
