I would love to know more about bikes, but the presence of more than one aftermarket part, don't know if they've been hard miles or not. Ducati!
Those are city bike mods, not track stuff. I actually run the same mods, except for the mirrors which I kept factory. I rip my Honda pretty good and it doesn't complain. Has over 3X the mileage of the Yamaha.
Both are barely broken in only ridden 1200mi/y. Mileage is halfway to the major service interval.
