Unsprung weight- curious
Anyone know what the actual weight of the OEM swingarm is? I've shaved 15-20 lbs of unsprung weight by switching to Sun aluminum wheels; I plan to take another 6-8 lbs off with metalmatrix composite brake rotors from Howard at Motorcyclemetal.com; and I'm thinking of buying an aluminum swingarm made by Metmachex(English co.) available through AR Harley & Sons. Goal is to reduce total unsprung weight by about 50lbs. When I switched to the aluminum wheel rims, the difference in steering was amazing. It was as if the bike would 'fall into the turns' when I leaned into a turn. Much quicker response, a cool improvement in handling.
So, anyone know what the OEM swingarm weighs? Jay

That's interesting. I have my original 1990 FLHS swingarm here which weighs in at just 12 1/2 pounds and a 2007 touring which weighs 16 1/2 pounds. I only weighed them on bathroom scales, which don't do decimals! The later one is deeper section tube and much more heavily braced. I have never removed my 03 Dyna swingarm, but it looks like my Glide's, so I would expect it to be similar in weight.
