OK, it's evidently called a collar. Whatever. Collar, sleeve, you guys know what I'm talking about. it's that thing that the wrench thing hooks on to so you can turn it to make it harder or softer. Or sag more an less.
Jesus, it's as bad a surfboards with the sex talk!
I think I found your solution. I searched collar sleeve motorcycle and found this for you, to solve the height issue. Pay attention to the riding boots.

Just a thought.

After yesterdays ride, I decided I was not going to lower mine. Today thinking back to my youth, the bicycle I had was a 26" and I was a small boy at the time. While on the bar I could not reach the pedals without moving back and forth on the bar. I never could figure why the step through frame was a girls bike and the bar right at the privates is a boys bike.
Anyway, after yesterdays ride, I feel at home on "the other woman". (
http://fuelly.com/motorcycle/ --keep track of your mileage), And with a couple of near drops in the hills, I am so much more confident with this she devil of a machine. I was impressed that I was able to keep the Terra from dropping. My other bikes, had they gone that far over the weight would have tumbled me. I guess there is alot to be said about putting the gas under the seat.
BTW, shock adjustment spanner wrench. When searching, the diameter helps get one that fits best. They handed me a minimal tool kit when I bought my bike, and it has the spanner. I'm on 2nd softest setting.
With that lowering collar for the spring itself, it may change the ride height (loaded) but will not change the mount height by much if any. Same with the preload of the spring setting. To me that is important, because the big issue is if the bike is on the side stand, throwing my leg over and getting the bike upright is a bit of a trick, especially on uneven dirt and full gear. I just try and park with the bike kick stand on the high side of the hill, not always possible. I need to practice a rolling mount, like I used to do with the bicycle.
Now if someone could make an AIR RIDE, like the lowriders, lower for parking, raise for riding, Nah, too much more weight.
