I'm wondering if anyone has ever tried lowering the bike by rotating the rear axle eccentric from the lower position A to position B
and then pulling the forks up by the same amount that this would change the rear ride height???

Any theories as to why this wouldn’t work???

I don't know the stick position it comes in - but looks like there will some meaningful loss in height. Will the chain position be optimal? But when you adjust chain tension over life you will gain height agin?? Ok I am confused.. But would be interested in learning too.

There were problems with the Streetfighter with the tire rubbing on the swing arm if the eccentric was in the wrong position. That's not the right way to do it.

I could see that possibly being a problem if clearances are as tight as the SF. It seems I remember the SF being an extreme example though. Even changing tires on it could make it rub.

Lemme get this right (not trying to be a jerk, just trying to understand).

You're seriously looking at an MTS for more suspension travel, should a curb come at you again. You had the rear on your ST at the stock position, for understandable reasons, but you're looking to lower the MTS right off the bat?

I don't believe that counting on the suspension in the case of an accident is what I'd call protection.

Maybe I'm getting the rationale wrong and you really want an MTS. If so, I think you'll want to contact Ohlins or Sachs to see what can be done internally or with proper links.

Again, all the best. I hope you're riding soon.

Have a good one.

No,no,no. I'm thinking about the Multi because there are no other choices I can see me buying. The only other bike I could consider is the Motus but its out of my price range. Personally I don't believe any road bike needs 8" of suspension travel.

I was looking at this possibility because it seem lowering it this way would do so without changing the suspension or chassis geometry by any significant amount.

Ahh. I see. Sorry for the misplaced assumptions. =)

The sus travel is excessive.

I'm there with you on the Motus. Even in the used market, they'd be WELL outta my price range. I'd like to see/hear one someday.

For me, I see either a replacement Duc ST or a well loved K 1300 S or F 800 ST. Or just keep my ratty ST running. If I could swing a second bike, the Ural 2wd is on the top of the list. With the side car, I could carry all the tools needed to keep it going.

Have a good one.

Just for the record, the suspension travel would be IDENTICAL with the wheel hub in either position. The only difference would be that the tire would probably bind on something under full compression. There is absolutely nothing in this proposed mod that would limit the actual rear suspension travel other than the tire hitting something.

True. Adequate clearances would have to be checked out.

hmmm if you swung the axle to position B to lower , then you may find that you turn the hub clockwise ( rather than counter clockwise ) to tighten the chain . it may mean an extra link in the set up ????

im guessing the rear guard could be lifted without too much trouble ... or at least less trouble that rotating the hub .

It's an interesting idea and one that I would like to see looked at just to see if it is doable. I'm guessing you just want to lower the seat somewhat and have no real intentions of going truly off-road correct?

Right. A 30" inseam doesn't much like a 33.5" seat height. :)

Haha. Oh shut up. And before anyone suggests Viagra I plan to do rides longer than four hours. :)

Finally, now I understand the reason behind the original question. It makes it more legit, to say the least. I found this one the other day and I think it seems appropriate to post it here:
