Hello again folks.

I'm purchasing a member's 5.5 wheel from his M900 part-out for my 2001 M750. He's offered me an excellent package price which includes the aluminum M900 swingarm..

I know my current steel swingarm will work, but is there any advantage to the aluminum swingarm aside from weight reduction? (if that).

Thing is, I already put a very nice coat of paint on my current swingarm, and slapped cool one-off stickers on it.

Just wondering if it's worth the hassle.

Thanks guys/gals

The only advantage, IMO, is appearance.

I like the look of the AL swinger.

I have a 5.5 rear wheel on my '99 M750 on the stock steel swinger.

And I agree with DP, appearance of the aluminum swingarm is more appealing.

But, I had the steel swingarm powder coated gloss black. It looks fabulous now. 

I've recently swapped an aluminum M900 swinger onto my '98 M750.

Best to get the M900 "non-offset" sprocket to go with the swingarm.

Clearance from the chain to the hoop mount on the swingarm is marginal.

When I get a minute, I'll post some details.

Just to make it more difficult, I've fitted a 525 chain/sprockets.

I too have swapped in an aluminum swinger on my 2000 M750.  As Speeddog said, the sprocket carrier from the M900 is key for chain clearance.  You will also need the rear axle from that aluminum swinger.   The beefier design makes the steel swingers axle too short.  I installed 520 chain/sprockets to give a little more clearance.

So...did it bolt right up? or did you need the parts that COP TZR and Speeddog mentioned? I'm a little confused

from what I experienced, the 5.5" wheel will fit into your steel swinger & axle and you can also use the sprocket carrier from the 4.5" wheel, but you will have to flip your front sprocket around for a straight chain run.

If you plan to use aluminum swinger you will HAVE to use the axle from the aluminum swinger.  Your steel swingers axle will be too short.

Follow what COP TZR said.
That's how I did it.

Thanks a bunch. Lookin' forward to those suspension risers and a fatty 180 rear tire
