Comfort is Overrated
Yo.
I took my R1 for a 2500 mile tour last summer. My longest days were about 500 miles. I have Heli-Bars which for the R1 raise the bars about an inch from stock (truly not such a big deal--probably where they should have been anyway) and a double-bubble "sport-touring" screen which is still damn small.
And it was great. After a 500 mile day I was waaay ready to go and ride some more.
Bottom line, I think that for most motorcyclists our definition of "comfort" is different than what non-bikers mean...anyone in a car just has a different concept of what is comfortable.
I suggest that reliability is much more important than comfort when you're on the road. Hey, I get stiff I can stop and eat, chat up the locals....if I'm on a motorcycle trip am I in a hurry?
But what profoundly sucks is to break down 50 miles from the nearest town with a *insert the brand of your bike here* dealer.
In a tangentially related idea, I just came back to Seattle from Medford, OR. It was hot and sunny and there were quite a few bikes prowling the freeway. 1. I'd guess that 80% of them were "uncomfortable" Harleys. 2. I also saw maybe 8 bikes on trailers and pickups. ALL of them were Harleys.
So where were the Honda Blackbirds and Yamaha FZ1's? Get out and ride, people!
And unless it's broken, no bike should be in the back of a truck on a sunny day.
