Early this AM, on a lonely stretch of I-95 in Florida, I did several runs up to max speed.
I had a GPS unit on my bike. This GPS unit is extremely accurate and give max speed.
I have a 2005, that just turned 10K miles this AM. It's in good tune, but all stock.
Well, my on my last & fastest run the bike's speedo read around 120 mph, but the GPS read 112.9 mph.
At a steady speed of 70 mph reading on the speedo, the GPS reads 66.7 mph, so I know there is error.
I was tucked-in and low as possible during the runs. I'm sure I may have gotten a few more mph's out of it had I more room, but those of whom have posted 120+ mph I believe are seeing a good deal of speedo reading error.
Keep Safe!
