according to expert Dale Wallker at Holeshot performance, Suzuki seemed to have created this motor to produce about the power/torque figures it does. With all out performance exhaust and other tweaks it may approach 100 hp at rear wheel (instead of 90/91) and more evenly lineal torque but that's about it.
But its quite a quick bike anyway; just effortless so it gives no great adrenalin rushes.
You could go a tooth less on the front sprocket or maybe 3 extra on a rear (some blokes here would know from personal experience) to enhance acceleration and get rid of some hiccuping down low but that's about it.
My advice is to run it in bravely, not nursing it nor lugging it but running it freely up and down through the rev range. Then get used to it over time.
A riding friend and myself both have this model and do not find stop/start/crawling traffic the least bit of a problem. Whether you have problems we don't or whether it's down to familiarity with product I can't say.
