I can comment here. I have owned 5 in line 4 600s and an SV 650. All of my 600s made power up top but only the YZF600R, not the R6 now called R6S, and ZX6R had any push in the midrange. All were good up to a point but the race reps needed to rely on hi rpm HP to get any real thrust. The SV did not have the Hi rpm to rely on but used the mid range torque to good effect. I did not know anything about mid range tho until my Buell! Bottom line the 675 is not a liter bike and dont have the big torque numbers. It does seem to compete well with most of its competition in the middleweight class...
