That makes 3 times I've seen it on Ebay...guess we don't want it that badly...
Would be a nice bit of bling, tho...
Oh to have a less limited cash flow for new toys.

It's posted on Craigslist (San Francisco), Located in Antioch.
Started at $600 the first time I saw it and the following times posted at $700.
Really neat stuff... I see value in the workmanship of anything like that, never the less is the Scorpion in need of something like that?
Wish I or someone had the coin and Scorpion to throw it at...

I know I would not want it and because of the price.
I hate those excentric tensioners, Got'em on the BIMOTA and they are damned nuisance.

Having never owned a motorcycle with that type of chain tensioning system, I would have never thought.
What makes them a nuisance?

It changes the ride height as you rotate the axle around. I personally don't push it hard enough to notice the difference but a change in ride height changes the sag and therefore changes the handling characteristics. My friend sold his Ducati in part for that reason.

[Bill Jurgenson]

of course, you can rotate the thing in either direction, so, in theory, you can adjust the road height and that is the man reason why they are used at all. I have it set to raise the tail.
Nuisance?
Again in theory, (socalled advantage) you can slip out the axle without even loosening the excenter so adjustment is not changed.
Big question: why remove the wheel (on a road bike) if you are not changing something? new or different tire? more probably new chain and/or chainwheel?

In racing, wheels are changed often and are usually the same wheels as set up, e.g. endurance where one set of tires is not enuf for the event and/or beginning(or ending) rain will not mean premature end.

But in the case of the BIMOTA at least, getting the axle out is not that easy:

You need to unscrew the retainer bolts (the allenhead, one on each side) and then screw in the threaded puller rod slightly smaller in Ø than the axle and then pull it out to let the wheel drop out and it is a very, very precise, snug fit. Back in, out course, you have to be dead on target going into the wheel bearing. You have be on target with any tensioner but here there is no leeway. Going back in, you remove the puller and snug the cap bolt in before hammering the axle back in with the rubber mallet. then the other cap bolt and both tightened against each other. In the case of the Bimota, with its end caps (which are far better than the circular clamp that alu swing arm has), the entire assembly can be dropped out and that is taken by itself a good thing in the shop.
I have exactly one rear wheel for the Bimota and since it can no longer be raced except for very special events, quick-change is not an issue. The bike is fantastic

but it is WAY TOO LOUD.

Louder than MotoGP, way over 130DB. Ain't nuttin in the megaphone and those open and polished 41mm Dellortos belch pretty loudly, too.

I want to keep it original (engine and exhaust systems, right or left side as needed, almost all NCR ) so that's that with the race track.
I have had to deal with this one rather too often for my taste. It is very sexy, looks devily good and appropriately high-end.
