Simply put, I can't see vehicles in the lane behind me until they are very close. When I adjust the mirrors so I can just barely see the hard luggage, the brake and clutch levers are dead center in the mirrors as are my gloved hands which block the view.
OK, I had the same problem with my previous K75 which the first owner had outfitted with fairing from a K100RS. For some reason, my wrists started to hurt after about a half hour of riding on that bike. The solution to both problems was barbacks. Ride all day and see at a glance what is coming up behind you.
I don't have the wrist problem at all on my current '92 K100RS, so really don't want to get barbacks (and maybe different brake lines.) If there is another solution riders about my height (6'1") have found, I'd love to hear it. .
