I think you have had it easy Wobbly...try blasting down the Autobahn at 105 mph for 4 hrs straight on a 1974 unfaired, stock CB750 with poor brakes
Actually, I do this all the time. The longest I wrote Autobahn was leaving Barcelona in the evening and arriving in Berlin the next afternoon, only stopping for gas. That is with my 77 K7 which I own for 36 years, having put on over 210,00 miles. Did I mention crossing the Sahara with my Honda yet? I am using the BMW currently because the Honda internals are finally getting an overhaul. And trust me, driving the BMW at speeds above 150mph is a lot more demanding. The "fairing" on the BMW makes sure that you get the full force of the wind in your face. It isn't exactly a touring bike, you see.
I have to admit: the BMW is more fun to ride. Every time I get on the Honda now, I feel that its brakes are atrocious. I hope to remedy this by adding a second front brake right now. In over 30 years, it never bothered me before. But that is because all my other bikes had brakes even worse (BSA, Triumph)
. Well, with the exception of my 1000 Laverda. But when I hit the Brembo brakes on the BMW the first time, I sat on the tank.
It is all a matter of getting used to. Most people who never ran, have a hard time finishing one mile. Then, with practice, people run marathons. You do need to give it a chance to adopt. And you know very well: riding in the Alps is so awesome, you don't want to stop. My long Autobahn hauls are simply a necessity to get there. And at temperatures below freezing, my behind it the last thing I worry about.
The reason I stop often isn't so much physical. I'm 6'4, 220 lbs, and 12% body fat. If you do the math, this equates to someone with a lot of muscle mass...I get mistaken for being in the army.
Well, I am 6'2, 255 lbs, and that isn't all fat either ( I am a power lifter). Accidently, people think that I am in the Army as well. Is it the uniform?
