I've had my GS for 18 months and I was so smitten with the idea that as a twin it is torquey, that I've only just started to notice that it's like an inline-4 when it comes to it's power delivery. You have to rev it to at least 5000rpm - 7000rpm to get the best from it and preferably 9000rpm (which is where its peak power and torque are (give or take)). I always thought it was torquey low down, but it isn't is it?
I know it's torquier than something like a Honda CBF600 at lower revs because I've rode one and discussed it with a mechanic who worked at a Honda + Suzuki dealer. (2 x 250cc cylinders versus 4 x 150cc cylinders)
I noticed this afternoon that it only really gets going at about 7000rpm+. (I've obviously been spoiled by the SV I tested a week ago)
So to conclude in a rather depressing way, its like an inline-4 WITHOUT the power! (hardly surprising when you consider it's only got half the number of cylinders of an IL4)
