It seems to me it's not the engineering overall, but the foolish assembly mistakes that put us on edge, for you can never know which bike will be a bike that got assembled with eyes closed! Triumph is said to use a single line and every bike of every model goes down that line. That has to encourage mistakes, you think you are putting a particular bike together, grab the parts from the bin, and it's the sister model! Blindly you stick the parts on anyway!
