Here's what I have written down:

standard front/rear: 319/314 mm (385mm torque arm)

early sport (until sep 2000): 330/318 mm (385mm torque arm)

later sport: 330(?)/310 mm (with 365mm torque arm)

Dave Hopkins has a great post about this in the torque arm thread. I plan to fiddle with this a little in the future, since my Fox shocks are height adjustable and I now have both long and short torque arms at my disposal.

FWIW, if you don't mind mailordering parts, the GS 365mm torque arm can be had from Chicago BMW for about $60.

best,

Dave
