I own a 2006 Sprint ST ABS model. I'm 6'4", 220+, mostly legs. The bike is a bit top heavy compared to my '03 9R, but that is due to the fuel tank being tall rather than wide.
With the upright seating position, and wider bars, the bike is very flickable. It tend to "fall" into turns, meaning that if i had the skill and mindset, I could wait longer to turn in than on my 9R. Instead I make newbie errors by turning in sooner than necessary!
Anyway, very manuverable bike.
The seat leaves a bit to be desired, thin padding. But eventually Sargent will have an offering. The pillion pad is supposed to be comfortable, and the leg position fairly roomy. The grab rail does get warm, and in the summer I imagine it gets a bit toasty w/ the exhaust just under the tail like it is.
Mileage has been in the mid to upper 40's, the power is linear, as you'd expect and I have not noticed any real flat spots or hitches in the injection. The heat issue everyone talks about is real, but if you wear proper kit, like i do, it is not a big deal.
I'm not a journo, so if you have other questions, fire away! Otherwise, that's my
