Having owned many bikes, including two Hayabusas, and a 2010 blade, which I px'd for my current 2012 cbr600f, I was naturally a little concerned whether I was doing the right thing.
My aging frame was finding the riding position on the blade a little too demanding on my back and wrists, and I was fidning myself wanting an all together more relaxed riding experience.
My bike usages is a 30 mile round trip commute through a mix of traffic and country roads, and the occasional longer blast on a Sunday morning.
The cbr600f is an excellent commuter bike. Very easy to ride and control, both in terms of easy handling and a throttle response which is glitch free and sublimely smooth and linear throughout the rev range, both of which give excellent, safe control at all times.
It's very comfortable for the longer trips too.
This all adds up to a very relaxing bike to ride. Very enjoyable.
Of course it lacks the punch of the blade or a busa, and the sharp handling and throtle response of the blade, with a much softer feel, but as I said, it makes for a very relaxed and enjoyable ride.
It really depends what you want from your bike, but for my usage and more relaxed riding style these days it suits perfectly.
The big plus points are the oh so smooth throtle response, easy handling and comfortable riding position.
The negatives - can't think of anything. I have had a couple of vibrations creeping in. The first time was the high screen I had fitted ( highly recommended for windblast at higher speeds ) and was resolved by adding some damping. Second time I just tightened up the fairing bolts ( after 1000 miles ) and the vibes went away again.
Should also mention I had an 04 plate cbr600f and the 2012 model is very different, most notably with more low down torque which I find a big improvement.
I also don't want to give the impression that the bike lacks excitement. It has more than enough power and handling to put a smile on your face when pushed a little harder.
Think that's about it.
So no regrets so far after the first 4 months of ownership. Just wish the weather was a bit better to enjoy it ......
