I have an ‘18 1090R. I just got finished riding the NVBDR. I’ve known for a while that my speedometer was inaccurate. I was using a cellphone gps and I believed it was displaying 2 mph higher than actual speed. Now I’m using a Garmin Zumo XT. Now I’ve learned that it’s 2 mph higher around 40 mph, 3-4 higher around 60 mph, and 4-5 mph higher around 80 mph. Anyone have any thoughts?

I have a 2016, 1290 Super Duke and a 2018, 1090 Adventure and yes, both speedos show me going faster that I actually am. The Pros: Won't get as many speeding tickets. The Cons: It isn't accurate and the bike's Odometer reads more kms/miles than what it really has. I talked to the dealership about it and they said there is nothing they can do...
