My thoughts exactly. It's hard to beat any Japanese bike.
Surprised Ural didn't make the list TBH. I see/read/hear more complaints about BMW, KTM and Ural than any other bikes. Pretty much in that order, too.
But it can be said that the most ridden bikes are the one most likely to break down, so that's food for thought as well.
I worked as a motorcycle salesman for a number of years, those Consumer Reports ratings matched closely what my Senior mechanics told me, THEY LOVED YAMAHA !
Typical motorcycle technicians come to admire the way things are designed, especially ease of repair and maintence.
Technicians get REALLY ANNOYED at motorcycle design that prioritizes cosmetics and gimmicks in the way of access.
Why should they care about how accessible repairs/maintence are ? Isn't it All just more job security for technicians.
NO IT ISNT ! Many times they are paid a set fee or what's known in the auto/MC business as FLAT RATE, meaning they may get paid less than the amount of labor time required to ACUALLY fix what's wrong. This is particularly accurate with manufacturers Warranty work, BOTH Auto and M/C WARRANTY repairs are similar in this way.
Technicians feel they're getting cheated many times, and frequently there's NOTHING they can do about it.
So........good motorcycle technicians. Especially Senior Technicans with YEARS OF EXPERIENCE, tend to favor brands easy to repair/service.
I have NEVER BEEN STRANDED by a Yahaha or a Honda. I understand each brands unique image and appeal, I learned to ride on two ancient Harley's, one was an old police Harley with a 'Suicide Clutch' an experience I ALWAYS remember fondly, BUT when it comes to hassle-free motorcycling, got go Yamaha~Honda.
