I agree that the article is crap but some of what they say I agree with. Anyone can make a ZX6R go fast around corners. However, if you had an SV rider follow a ZX6R rider through someplace like the dragon and the SV rider was able to stay on the ZX6Rs tail I bet if you asked each rider about their ride the SV rider would be stoked and the ZX6R rider would be embarrassed.
Personally, I find it a lot more fun to ride a slow bike fast then a fast bike slow.
For instance, A month or so ago, I was toying with the idea of getting a used R1. I took it out for a 30 minute spin and it was absolutely awesome, keep the tack below 7K and it practically steered it self. Riding around above 7K is where things get interesting and this is where you risks lose of license or more. After my ride I though what an awesome bike for the track but a boring OR dangerous bike on the road depending on how you ride it.
After riding the R1 I thought my SV was quite involving. Not from a speed perspective but from a user involvement perspective.
FYI, I also have a BMW R1200GS which I took on a trip through VA, NC, GA, and TN with several very experience rider on liter bikes. Sure if they wanted to they could leave me on straights and if they were pushing it on really fast sweepers (>90mph) but this would only happen if we were seriously exceeding the speed limit. I am by no means a great rider, the GS just conveys confidence when cornering and is a blast to lean way over, way more fun then a bike with wire wheels and knobby tires
FYI, I was carrying most of their camping gear on the back of the GS ;D
