I probably spent the greatest percentage of miles-traveled-on-a-motorcycle on a 1983 BMW R100 RS. That's the German cop bike looking one. You can stay dry in the rain on one provided you can keep going about 55 or better. It's sweet spot is between about 80 and 115. You can go 100 all day in total comfort.
The down side is that it's slow and agricultural compared to any "modern" motorcycle, it has no power, weedy brakes, sh1tty suspension, and a general lack of refinement. The upside is that you can rebuild one in perpetuity should you never want to buy another motorbike, and it's a "classic" in the same sense as a BMW 3.0 CS car.
I had it, an RD400 Daytona Special for ages. I recall I bought it in '89 I think. Eventually the race bike left and I got a '93 Ducati 900SS, then added a '98 GSXR600 for track days. The Duc left to fund an '06 DRZ400 supermoto, then the GSXR left after buying a KTM 950 supermoto...
Still I kept that BMW, although it had been converted to an S by now.
Finally, I realized I rode the SuMo-s all the time and never rode the old BMW anymore which wasn't fair to it.
I sold it to a guy who really, really wanted one, and he loves it and has learned to work on it and I'm genuinely happy he has it.
Then I bought a Derbi 50 supermoto and a KTM690 SMC, and in fairly short order sold the DRZ400 and the Derbi.
Now I have the 2 KTMs - a 690 SMC and the 950 SM, and that RD400 Daytona Special which is going back together with all the stuff I'd wished I been able to do when I got it 25 years years ago. And I have a 2003 Yamaha Zuma 50 scooter w/a Valentino Rossi replica paint job/pipe/carb/springs-weights.
So - from full fairing to no fairings at all. But I'm intrigued by the Honda deal where 2007 VFRs are on blowout at $7399, including the ones in the 25th anniversary interceptor paintjobs. Lose the 950SM, lateral into a new 2007 VFR...
