Swingarm question

[bdfinally]

Hey guys this is an aluminum swingarm, right?

[Yorkie]

Looks like one, try a magnet on it.

Those are nice chain adjusters.

~~~SNIP~~~

Yes, definitely.

Any problem making that work with a 2000 M750 dark?

[Yorkie]

It should slot straight in, it will also allow you to run the wider 900 wheel with ease.  I used one on my M600.

You'll need the chain rub strip, it's different from the steel swinger.

Probably should get the sprocket carrier for the wide wheel, and flip the front sprocket flat side out, so it all lines up.

I'm thinking of this as a winter project, so I'll need another cush drive then to have everything line up even with the OEM 750 wheel?

The Cush drive will be fine they are all the same.  The front sprocket might need turning around to align it, I cannot remember if I did or not.

You can keep your 750 (4.5" wheel) sprocket carrier, and keep the front sprocket 'hub side out', but the chain won't line up with the rub strip.

To get the chain to line up with the rub strip, you'll need the 900 (5.5" wheel) sprocket carrier, and flip the front sprocket flat side out.
I've got that exact setup on my M750.

What'd ya'll think the weight saving on that AL over steel is?


And again thanks for the guidance, guys

What'd ya'll think the weight saving on that AL over steel is?

From an old thread:

The steel is 11.4 lbs
The alloy is 9.6 lbs

i thought it was the other way around: aluminum box swingarm wasn't lighter than the steel ones because of the additional thickness to the box, but it was a whole lot stiffer.
