I just installed SpeedoDRD speedometer correctors on my GL1800 and on my CRF250L (each running stock tire sizes). The Goldwing needed a 6% correction factor to bring it’s speedometer to match 2 different GPS units. The CRF required 5% correction to match two different GPS receivers. (Of, course, I would never expect the different GPS units to not match each other anyway). I have no idea what speedometer accuracy requirements the US might have, but if it’s 3%, Honda and other motorcycle manufacturers have been getting away with a lot more than 3% error for a long time.

Maybe you meant odometer accuracy. I have not checked my motorcycle’s odometers for accuracy.

I have not personally witnessed a GPS receiver with good satellite signal reception displaying incorrect speed.
So I went back and tried to find it and I don't know where I got 3% from...it definitely was not odometer accuracy though. The actual speedometer accuracy is determined to be +/- 5 MPH at 50 MPH. Now whether that means within 10% across all speed ranges or what, I don't know. But also leads to why you typically won't get pulled over on a US highway if going 5 over the posted speed limit.

A 10% speedometer accuracy mandate sounds probable. Up until the NC700X, all my past motorcycle speedometers were wildly optimistic. The only motorcycle speedometer from long ago that was dead on right was on a 1982 Suzuki, and it had the mandated 85 mph speedometer with 55 highlighted.

In the US a vehicle's speedometer has to be accurate to within 3% +/-, so I would lean more towards the GPS being off than the speedometer assuming no modifications were made that could affect the accuracy of the speedometer. While a 10 year old motorcycle could be off of that since it most likely has never been recalibrated, a new one will definitely meet that requirement. What affects the accuracy of the speedometer depends on where it is pulling the speed from, but can basically narrowed down to the size of the sprockets and/or rear wheel. Meanwhile, a lot of things can affect the accuracy of GPS. The only real way to tell if it is accurate is to take it to a calibration site or ride past one of those roadside radar signs and compare.

On a different note, how much do you and your wife plan on riding off-road/to your cabin? Reason I ask is she might be better suited on a lighter bike until she gains more experience. Now if this is going to be a once in a blue moon trip then I can understand not wanting to purchase a bike for just this trip in mind, but if it is going to be more of a regular thing I would recommend rethinking the NC route. Reason being is that while the bike doesn't feel heavy, it is and new riders tend to tense up and try to fight the bike when riding in
Plans are on hold. My sweet wife of over 40 years is in treatment for Leukemia, newly diagnosed.
She had wished for Africa Twin, I suggested NC750 and she was totally sold.
Now we just wish for a few more years together somehow.

Nothing else matters now - wish both of you the best in the days ahead.

Relatively good news. She is surviving Chemo. Three weeks of hospitalization so far and more to go with no visitors, but it is looking like we will be able to see each other again. She is tough. She rode her bicycle with me to Alaska in 1978. Did I say she is tough? She is also the most beautiful woman in the world. If she gets a good period of remission from Leukemia, who knows? She may want that new NC750 after all.

More good news. Actually GREAT news.
My wife is in full remission from her cancer and is looking forward to a long life with new appreciation for all that living life to the fullest has to offer.
She has put down a deposit for a 2021 NC750x and is looking forward to her red 2021 to arrive in late May, just in time for her projected full-energy recovery from Leukemia treatment. She is of Medicare age but does not look it. Most likely her fitness level helped her in her cancer treatment recovery.
She originally hoped for a White NC750, but she says life is too short to wait until Honda makes the white ones available in the US. She will take the red 2021 NC750x and possibly add some aftermarket decal-based pinstripe white and blue streaks to make it look like a one of a kind 2021 "mini baby Africa Twin". :)
Did I say my wife is tough? She is, and she also has a flair for fashion.

Back to tires.
Since my wife is going ahead with her order of a 2021 NC750X, she will ride OEM tires until we head off to mud country. Being optimistic about her cancer recovery we pre-purchased a TKC80 front and a TKC70 Rocks rear (between TKC80 and TKC70). The Continental tires will be great for highway to get us to our muddy roads.
My VStrom has TKC80 front and Motoz Tractionator GPS rear.
