Although I love my K1200GT, not all the ergonomics worked for me at first. One of the things that gave me the most trouble was the shifter- it seemed too low, and I sometimes had trouble reaching the shifter to upshift- barely enough room for me to wedge my foot straight down. While shifting in corners, I constantly found my toe dragging. The shifter does adjust for the higher footpeg position, but it rotates backwards, not forwards!
At first I was puzzled by this, since BMW is usually careful to assure good ergonomics. Then I remembered how on vacation I'd tried to buy shoes in Munich, and discovered that no shoe store (and I looked at many) had a shoe larger than size 10. I literally could not find any shoes that would fit, apparently Germans have small feet.
This would explain why there's so little room between the left footpeg and the shifter on a K12- it's probably fine for a german foot, but not for mine.
I didn't do anything about it at first, until one day I discovered the K12's tendency to fall over when carelessly parked on the sidestand. You have to be careful that the ground is level, and the bike is in gear, or it can topple. I heard the sickening crunch as my poor bike got its first scratches (although they were minor).
However, it fell right on the shifter, which snapped right off. Fortunately you can still ride and shift with the end of the shift lever broken off, though it's no fun.
Safely back home, I examined the damage, and discovered that the fall had broken off part of the shifter rod behind the lever end. But not only would the shifter lever fit back on, the damage had gone more than halfway toward modifying the shifter to accomodate a more forward position. Figuring I had nothing to lose, I fired up my trusty die grinder and set to work finishing the job.
