Will still be fast in 20 years time
I had a few mega fast bikes in the last 25 years, started with a GPZ900R, then a ZZR1100, a couple of ZX9R's and then a ZZR1400 with other bikes thrown in between but I always ended up coming back to fast sports tourers.
The GPZ900R was on the edge of what was remotely useable on the road, the ZZR1100 was OK, but the ZX9R's and ZZR1400's made me do things that could easily get me locked up and refused to be fun until your travelling at a speed gauranteed to get you banned instantly.
I liked my GS and my current steed (Super Tenere) as you can still use the performance, flat out in third on either is around 80, on the 1400 it was a genuine 138 (indicated 145+) and you can almost his flat out in 4th and still be below 100mph (165 on the ZZR - On an Autobahn of course) I also cannot use the grip of a dual purpose 150 section rear tyre.
Riding 100BHP (but heavy) bikes reminds me of burning around country lanes on Watercooled RD's "back in the day" fast, fun, and useable and I could actually get them to misbehave when pushing, my Tenere shrugs at my pathetic attempts to ride it to the limit, a modern sportsbike must just roll around laughing at me.
With the way the UK roads have fallen apart, and got seriously over congested means the bumpier back lanes are now where I ride at home, and when I have time and money I head to Vosges, Black Forest, Pyrenees or (of course) the Alps, places where hyper-bikes have little or no advantage.
I am probably just getting too old, but can't see me going back to a reallt fast bike, sat on the new ZZR the other day and I wondered how I ever got out of my own postcode on one and cannot believe we used to do 3,000 mile trips on the thing Still want one to Polish and keep as a classic, but not to go far on.
