Hi - Tuesday I'm supposed to go and get this new 2017 KLR 650 and it has 17 miles on it. No scratches or anything. Should I have any concerns? Should I just treat it normally as I would a Motorcycle with Zero miles?

I would imagine it’s been used for demo, which is no reason to consider it any less than a new bike.
Do the recommended break in and enjoy the bike.

I have never seen a new vehicle with zero miles, although I suppose it is possible. In my mind, 17 ~ zero. If the bike has never been titled, and is being sold on an MSO (instead of a title), it would be deemed a "new" bike (first retail sale).

I bought mine with 34, from the first owner, via title and bill of sale, therefore mine was "used", despite the low miles.

What they said; I've purchased many new vehicles and they all have some mileage on them. I'd consider anything less than 100 miles to be "new"....assuming you are the first person to register it.

I agree.
Just rolling them in and out in the evening and morning adds some miles to the odometer unless they disconnect it.

on another car forum I frequent, the thought was that a brand new car accumulated 20 - 30 miles just in testing, loading and unloading, etc.
