Pros: Comfortable, snappy and fun, reliable, looks sharp!
Cons: Lacks high end torque, will be outgrown by the more serious sport bike enthusiasts.
The 750 Katana is a great bike for any beginning rider who wishes to enter the world of sport bikes: It's fast enough to be fun and light enough to maneuver with ease. The downfall is that any serious rider will become board after a short time of riding the Katana. I had ridden cruisers up until I bought the Katana and being new to the world of sport bikes, I loved the bike to begin with, but quickly outgrew it. After one season I traded up to a Hayabusa.
The rake is aggressive and makes for easy cornering, you can turn a nice, tight circle; the wheel base contributes to a comfortable stability, and the seat height, at mid-thirty inches is a bit tall. I am 5'9" and was on my tippy-toes, but the bike's weight of 384 pounds makes up for that. The seating position is not aggressive and quite comfortable. My wife was very comfortable riding two up. The most miles I put on in one day last season was about 350, and my bike was fine, my wrists were fine. The pegs are set up rather high and I did get "crampy" in my hips, though stopping to stretch, gas-up and so forth, helped. My wife was stiff, though she's not used to sitting still that long. :-)
The gearing is short. The power band is between about 3 and 5 revs. The bottom end torque is strong and the bike is snappy in the low end; high end torque, in my opinion, is lacking. Riding two up, the low end torque was still surprising and fun. We didn't ever feel "bogged down" riding in the higher gears, cruising, although compared to say, the GIXXER 750, there is a substantial loss of horsepower at two up, in higher gears. Again, for a beginner's sport bike it is fun, but will be outgrown after a time if you are to get seriously into road racing motor sports.
In the season I had it, I changed my oil at 600 miles, again at 3500 miles, and just before winter storage (per manual). I tightened my chain to specs once. That's it, that's all the maintenance I did, and I never had a problem out of the little gem. The bike ran very well and never "left me wondering." The Katana is a very cold starter and runs very hard when cold. As I recall, it took some time to warm up. Oil changes are a little involved as you must remove the entire lower fairing to get to the oil filter and crank case.
Overall, for the price, the bike is a great starter bike.
