Lowering a K1200S so that the Dragon can ride it

Problem started when i bought my first K1200.. i loved it, she loved it
No problem you would think.. she sold her 696 Ducatti and wants to ride the K

Problem 2: She is only 5"2" and can not touch the floor, although she adores high heels refuses to wear them on the bike and drops it stationary nearly every time she rides it

I fixed problem 1 by buying her one of her own, identical to mine ( tags are His and Her's)

Not yet found a way to fix problem 2 ( note she is my 5th wife so while it could be an option i think ill pass on that one)

Put a Sargent seat on it which says it lowers it 1 inch.. ( they are taking the piss, its identical in height) changed the bars so she sits more upright, bought her thick soled boots, but we still need to lower it about 2 inches..

Any ideas, scarcastic, funny or plausible welcome


By the way just started this FB page:

enjoy and add

First off, I would assume you have installed frame sliders by now...if not, good idea to reduce future damage? Second - maybe see if there is a 'custom bike' seat manufacturer in your area like Corbin here in CA. When I was in their shop a few years ago for my RS seat, there staff was constructing a seat for a custom low-riding big twin bike. The bike frame was very custom welded, so required a seat be made from scratch. The man placed some sort of wax paper or something similar on the tail end of the tank, down onto the frame tubes and back as far as he thought appropriate (going from memory but it was an interesting process to watch.) Next he started applying layers of a paint on fiber material with a brush applicator. He painted it on in the general shape of the intended seat pan. After each layer cured (20 minutes or so?) he put the next layer on. By the time I left, he had the pan for the seat formed such that he could pull it off and cut, grind, whatever to the final pan shape, then he would add the foam and a leather cover. Perhaps you could have this done. I always wanted to try it for my wife on her R1100R because we could never get it low enough for her. All seat folks (including the custom from Corbin) simply reduced the amount of foam padding on the pan and it was like sitting on a board. I have no idea how expensive or comfortable this might be, but that was how I recall Corbin build a custom pan/seat for a 'custom' big twin. (H-D)

Contact Klaus and see if he can make custom suspension that will lower the bike. http://www.wilbersusa.com/aboutus.htm

Did you lower the bike? If not, contact Works Performance. There is little that seat lowering can do for shorter inseams (may be 1 inch and lost the cushion).

Dude,
You're in Jax. Sargent is there. Why not go over there and ask them to custom lower the seat?

When I communicated with Klaus some time ago he suggested that it is "reasonable" to lower ride height by about 3/4" without significantly compromising handling. Have you yet explored ordering shorter shocks to lower the suspension?

I was talking to some one yesterday about lowering my bike and they said it would change the handling characteristics, inferring that it would be dangerous. But I wonder if an inch could cause that much of a difference? If you put a 140lb rider and then a 240lb rider on the same bike - wouldn't that change the ride height and handling also?

There is always lots of talk about the negative effects of lowering a bike, but I wonder how much of that is based on real science. I would think anyone setting up racing bikes would have a definitive answer. I would love to lower my bike an inch, but not if it's dangerous.

I lowered my R1150GS by 2 inches (front and back) and added a 2 inch riser to the bar and had no trouble riding it. I could not lean the bike as far as the stock set up which is not a bad thing. I just had to learn to lean my body out properly and I could keep up with other R bikes in the twisties. My understanding is that the taller the backend the faster the bike will turn. Since I don't ride at racing speeds around corners, I don't see a geometric problem with lowering the rear.
