Is the s2 a quick bike?

[JoeRock]

I think my topic has been misunderstood. What I am saying is for a 600 non sports bike it's very very quick. If let's say I was on my local runway it would hold its own with much more powerful competition all the way to 120mph. 
And yes I ride with enthusiasm to the red line when the time and road suits

Yes it is pretty quick, but in fairness most of the other 600cc non sports bikes put out a fair bit less power! Banit, sv etc. Only one that would be able to keep up would be a hornet 6 (and probably the Z750, but that's also a bigger engine!)
I can tell you though that it wouldn't keep up with a rider on a bigger bike that wasn't actually afraid of opening the throttle fully! Back when I had my Ninja 9 (which in itself was an older bike, but still 145hp/190ish kilos) a mate of mine back home bought an S2 (it was the RWU forks, but bluespot calipers, think that's an S2?) and was raving about it, he could pull off a little easier from the line than I could as it'd wheelie, but after that I'd literally destroy him! No matter what people say, if they are willing to ope the throttl fully on a liter bike then in a straight line there's no replacement for displacement!
