"I've read how the speedos are 10-15 mph off, I didn't find that to be true.  :D  First was my '01 s model with stock 120/60 Metzeler tire. I was very steady with speed control and triple checked readings. 45 mph is actually 44, 60 is 58, 70 is 68, and 80 is actually 77.8. Then I checked my '00 naked with a Pirelli 120/70 on the front and got the same readings. The thing that is out of wack is the tachs. Both read 5000 rpm at 70mph but the naked bike has a 14 tooth counter shaft sprocket and the S has a 15 and 1 less tooth on the rear.  :?"
