Sit up and Beg GT

I bought an '08 K12GT recently and immediately missed the sit up and beg rider position of my R1150RT (and my K100RT before it). I upgraded my windscreen to a tall Pope-mobile sized Aeroflow with the Aeroguards on the sides. I got the Suburban Machinery foot peg lowering kit and bar backs which put the rider position really close to my R-bike. It's close to the real sit up and beg now.

The jury's still out on the seat. I took the rubber bushings off the back and it's helped a little with the nad crushing forward tilt. I may still wuss out and get a custom seat later.

I know it sounds like I'm trying to convert it into an LT, but with the windshield down and the luggage off, she's still a GT.

Does anyone else like a cushier GT? What farkles have you done?

I actually find the slightly forward leaning position of the GT is very comfortable for my back. It encourages a slight lordosis in my lumbar spine, instead of the slouch (reverse lordosis) of a true sitting position. (Please excuse the jargon; I'm a neurologist.)

I've also worried about lowering the footpegs, as it might limit the wonderful leaning ability of the bike. Much of the fun of this bike is it's sport-bike turning ability. Have you found this a limitation?

I'd worry a little bit about a very high windshield being prone to cracking, and find the currently standard "high" BMW windshield gives me great protection (I'm 6' tall), and it's seemingly very strong at all speeds I've achieved ;<).

What's the best cure for my hands going numb rather quickly when riding? My old K75S had the same effect, so I'm about done blaming the bike.

Hi Gilly,
I think it is pressure on your median nerves in the carpal tunnel of your wrist, made more problematic by the slight vibration in the grips. I have the same thing in my throttle hand, where I know I have mild carpal tunnel syndrome already. I've had surgery for CTS in my left hand, and rarely experience the problem there. Probably the leaning posture and vibration are a sort of "stress test" for mild carpal tunnel syndrome.

One thing that helps me is to just consciously use my back muscles to hold my body slightly erect, unloading my hands at the grips. It is only slightly tiring, and relieves the pressure on my wrists. Good isometric exercise as well.
Best,

I stuck on a pair of tank grips on my bike - helps take some pressure off my upper body. My knees rest against the grips and helps keep me upright, as opposed to holding myself up with just my arms and back. Keeps me from sliding forward under braking too.

Sorry - on a loaner computer, don't have a link to their website. They're cheap, like $40 or so. Nice add-on.

I've done the same modifications to my GT to get to the riding position / wind protection that I liked on my R1200RT. A Russell seat is next, and if that does not do it for me I am thinking about another RT or quite possibly a Triumph Tiger.

As for your hand going numb, I tend to have the same problem. High frequency vibrations do it to me, and not course vibration like you tend to get on your old boxer.

Here's a side by side comparison of the ergos. Note that even with my SM bar risers raised all the way, my arms are still noteably lower than on the stock RT. Also, my knees are bent significantly more even with the SM pegs.

Looks like you're almost sitting on the pillion on the RT. Is that what you're after?

I noticed that also. I don't remember it being intentional either.
