I weigh 160 lbs and have always ridden the heavy XR600 and now the 650R better that anything light. I used to have an 01 650R that I seem to remember being able to dial in (the sag) perfectly for my weight (1 inch static 4 inch loaded). I made an error in judgement and spent a very brief period on a WR426, but now I am back. On my 02 650R I am ending up with 1.5 inches of static sag when I set up for 4 inches loaded. Maybe I just did not realize it on my 01. I don't think they changed the stock spring rates in any of the years, but correct me if I am wrong. In either case, does anyone know what weight range the stock spring is good for. I notice most people tend to have to add a stiffer spring, but I am wondering if I need to go the other way. I loved the way my 01 handled and it was totally stock in the suspension department other than dialing it in. Thanks for any info.
