Has anyone replaced the standard steel swing arm with an aluminum one? Any guess as to the weight savings,and is this worth doing? If so anyone have one for sale? I have a 1997 750m,and trying to make it handle as well as it can,in addition have upgraded the shock and forks.
Thank you.

From what I've heard, it's not much lighter, if any.
Should be a bit stiffer, though.

I've got one of each sitting downstairs (I was going to switch to an alu one, then I lost my mind and had Norm make me one ;D)

The aluminum one is definitely lighter. But not by much.

Mostly I was going to do it because the aluminum swingarm just looks that much better...

As for the swap, it can't be too hard if a chimp like me can handle it. [laugh]

I did that on the 750, again not for weight reasons but to enable me to fit a 5.5 rim. They do look much nicer though [thumbsup]

I did it on my '97m750 too. Did it more for looks and spindle rear lift, than weight savings, though it did weigh less than the steel. Also got a 5.5 in back but that was only because I got a great deal on some forged wheels and that was the size it came in. Don't buy into the big back tire. It's more nimble with the smaller back.
