The problem with such a study is that it doesn't qualify anything. What constitutes "failure?" Number of miles at failure, etc?
For example, it's interesting that BMW also rated very poorly. If you ask 100 experienced riders which three makers of motorcycles do you believe average the most miles annually, I'd guess it'd be Harley, Honda and BMW. They have the most popular touring motorcycles by far.
You'll find 4-year-old Harley touring bikes all day with 50-60K miles on them. The same can be said for 'Wings and BMWs. How any Yammies get ridden like that?
The problem with research is that you can get the answers you want by asking the questions you want.
What Thunder says is true. Not so much with Nanny magazine CR. Not hard to miss in other publications.A habit I have gotten into any time I read a "glowing to good to be true product write up" in any magazine.
Pay attention to the advertisements in the same magazine. Oddly enough many times you will find one for the same product written about so highly. :think
