It's the way you do it !
I think he's going a bit OTT on this. When I test rode the bike, about 15 mins into the ride, I went through a VERY busy town. Rather than going on and off the throttle, I was slipping the clutch - did not cause me any issues, I just realised the biked is very eager and found using the clutch a better solution than on-off the throttle. Have to say, enjoyed blipping the throttle, just to listen to the engine through the airbox !
It would probably be good for Suzuki to put their power options/modes on the bike, then you can select a much milder power with a much gentler throttle when in town. However, I suspect they didn't have that in time for the launch, and wanted the bike out to market. Probably will come in with V2 of the bike in a couple of years I guess.
Once power commander comes out for the bike, if I hear it's a major benefit, I'll go for it. Just as long as it doesn't tame the beast !
