Vibration or a slight buzziness? I was asked to do the break-in kilometers on a new 500X for a rental company here in CNX a couple of years ago - thought it was a smooth runner up/down through the gears.
But then, WTF do I know, my first "big bike" was a 1945 Indian Chief? The bar ends moved (vibrated) up and down 20 + mms at idle or any speed. The H-D I had next, a 45 cubic incher, had the same bar end movement, as did the next H-D. I logged a lot of miles on those three motorcycles, thought nothing of vibration. Part of the evening check-list was to tighten nuts and bolts from a day of vibrating. Photo is my '46 Indian Chief - vibration is part of the operating function, let's you know the beast is running.
I suspect you'll not find your 500X needing any evening wrenching to keep things like the front fender from falling off the next day (part of my Indian and H-D learning curve) . As you noted, the vibration wasn't there with the lady on the back - if going solo load your top box with 40-50 kilos of bagged cement?
My take-away on your Honda - great choice, one or two-up, with or without the kilos on the back. Give us a little reportage after 1,000 kms?
