bmitch,I've got one of those Dymag carbon fiber swingarms on my 916SPS, I put it on about 10 years ago. I have ridden the bike almost exclusively on the track and race it in AFM.
Here are some photos of it on the bike in the original c/f and the when I was rebuilding the engine I had it painted to protect it from UV rays as the can degrade c/f over time.
The lowest weight Igot it down to was 384 lbs. without fuel, on Intercomp scales. That was with one of those really small dirtbike batteries. I've since gone back to a newer 999 size battery, so it's probably about 389 lbs. now.bmitch,
That 916 looks like you put some major work towards lightening it, not to mention making it look good in the process. Do you know what you actual bike weight is? Very impressive set-up I must say!
