So I'm taking off for my first weekender with the DR. Doing the CANOL Road with 3 other DR's, an XR400, and KLR (one of the good older models) Anyway, I've got about 80-90 lbs, plus my 220. I'll put the sleeping bag and thermarest on the fender, no need for a headlight, its all mining roads and off road. IMS tank, eibach springs, new 606's. How much weight is too much?
