These threads confuse me a bit. I sanity-checked the speedo on my new 2013 Glee against 2 other bikes - a R1200C and a K1200RS - on Sunday, and where they indicated that they were holding 60, my speedo was showing 60. We did the same at 50 with the same result. Perhaps I'm a sucker, but to me those quick comparisons were enough to satisfy me that the speedo as-is is more than close enough. (note that I don't ride with GPS, so I have no idea what the satellites would have said)
My question is... is it simply a coincidence and my bike and the two bimmers all apparently had the same error, or is it possible that all bikes are not stricken with this?
