Torque arm: any experience with adjustable version?

I'm stuck ... stuck in between. On one 1100S I have the stock torque arm. On the other I have a short version. So I think to myself, perhaps an adjustable one ...? (Keep in mind I will only keep one of the two 'S bikes)

I like the longer version because it puts me closer to the ground and feels a tad less inclined to turn in. Great for around town or on the highway. But then I hit the twisties, and the shorter one feels great, easier to make a fast smooth transition.

So, Can anybody answer these questions for me:

1) How long is the stock torque arm?

2) How long is the short one (from GS)?

3) What lengths can the adjustable one be set between (i.e. what is it's shortest setting and what is it's longest setting)?

Very curious if that would solve my dilemma...

I would like the ajustable one too. My BC is really tall for me, 5`10. I have good balance but I`m still on my tip toes.

Crunch,
I was given an adjustible torque arm for my BCR.
Very nice in construction.
It has the initials MV as the company set in metal and is called the 'sport'.
Unfortunately,for me, the shortest it goes is 370mm.
Since I'm more into corners this won't work for me, but it really looks nice,heavy bling factor.
cya

Jeff - good inputs, thank you. I'm interested to try out an adjustable unit.

Does anybody have experience with this one?

Sideshow -- thanks to you for answering the specific questions. Hard to believe 20mm makes such a difference, but then its in the overall geometry.

Hi Crunch,
I've mounted it some years ago, it's very well done and practical to use. I keep it long when I need my centerstand (touring or everyday use), I shorten it when I want to have fun on mountain roads. A great improvement in my opinion.

Jeff,
It would seem to me there would be quite a noticeable difference between 385mm and 370mm, and a little difference from 370mm to 365mm. I'm just trying to decide if it is worth the purchase.

Hoots,
IMO better to spend the $64.70 for the GS torque arm and decide if thats want than buy the adjustable arm.

Just installed an adjustable on my '99 S. Cranked it to mid point between Stock (385mm) and BCR (365mm). With it set at 375mm I can still use the center stand. Could definately feel that the seat was higher, my legs straighter when stopped.

Cornering is quicker and firmer. The bike seems to lean into the turns better and find the line on its own.

So most of what I'm experiencing is probably placebo effect, but I like it. And as far as weight difference, I could not feel any. The all aluminum adjustable is about the same as the long steel.

Bling factor is about 1000 times better, too. Stamped steel, how cheezy!

Yes, Jeff, it is SWEET! Still have trouble believing that a 1cm change in the articulation of the rear end could have discernable effects, but it sure seems to. I'm not going back to the longer arm any time soon.

You haven't just changed the articulation of the rear, you've moved your body position forward, put more weight on the front, shortened the wheelbase, and mildly changed the angle of attack the rear spring acts upon.
