So um, I'm going to admit that I've never ridden a supersport before. I've sat on them, I've stared at them, but I've never ridden them. Well, that changed this past weekend. My school's motorcycle club did what we call a parking lot day, where we set up cones (tennis balls in our case) and practice different maneuvers like slaloms, figure 8s, etc. My buddy just bought a CBR600RR so we swapped bikes for a little bit and got to see everything different between them. My impressions, coming from my ZRX were as follows:
-First thing I noticed was the weight difference. Coming from my ~550lb ZRX to his ~415lb CBR, I felt like I was on a toothpick. I could rock the bike back and forth with no effort and reversing was a breeze. This bike is even lighter than my GS500 was, I believe and it's very noticeable.
-From there I noticed the body position. I'm 5'9" and around 160lbs. Very average build and it still felt cramped. I said reversing was a breeze, but it really limits how much you can look around when you're hunched over the clipons like you are. And when moving, it felt intuitive and fitting with the windshield but my back isn't meant to bend like that for more than 15 minutes at a time.
-Once I was moving, I got a feel for the engine. We were in a big parking lot, so I had plenty of room to open it up and I did. What I noticed first about the engine was how gutless it was compared to the ZRX motor. On paper, the CBR has more horsepower but a bit less torque (about 25 ft-lbs, I think) and you can really feel that difference. The ZRX pulls consistently from 2k RPMs but the CBR is really high strung. I had it up above 8k for a chunk and it felt like it was pulling harder, but still not that much. I imagine the power really plays a part once you're hitting triple digits, where the ZRX starts to mellow out.
Overall, I enjoyed the opportunity to ride a supersport, but it also convinced me I don't want one for anything other than a weekend ride. It just didn't seem comfortable (in posture and in engine temperament) for street riding.
On the other hand, I rode my other friend's dualsport, although I forget what it was, and that pretty much drove home that I want something for offroad riding. I took that thing around the fields and hills next to the parking lot and it was so much fun.
