Speedometer incorrect?

Has anyone ever notice their speedometer was incorrect? The reason I bring this up is last Thursday on my way to the dealer for the 600mi service it was approximately 60 highway miles in each direction. I have a phone mount and the displayed GPS speed was 5mph lower than what was displayed on the bike. Maybe thinking the GPS speed was off I got in my truck the next day to check the phone GPS and it checked out fine. I also have a speed sign near my house in a neighborhood that I checked at 30mph on my speedometer on my truck versus the GPS on my phone. It all checked out. I checked this out at several speeds on the bike. At 65 I was really doing 60 per the GPS and it was consistently 5mph off at numerous different speeds.

Check your manual...it's off by 5% on purpose...legal reasons...keeps you thinking your speeding but actually do 5 under...you adapt
