My motorcycle chain had become too loose and needed adjusting over the weekend. A friend came over to show me how to do it. The process was loosen the wheel nut (large nut in the above photo to right) , then first loosen the outer nut and then turn the second nut until the correct tension was found. What I found very interesting was the consideration Honda clearly had for us home fixers. Normally the two nuts would be the same size but most people own one spanner set with each tool being the next size down/up thus making it impossible to adjust the nuts at the same time. Honda have obviously considered this and to my surprise the second nut is the next size up thus allowing me to use the next spanner in the set and make the adjustment without having to borrow another spanner from a neighbour.
This small detail to me demonstrates how Honda have carefully considered the “real” world and met my user need before I even knew it. They could have used identical nuts knowing that would likely result in the user having to stop the job and seek out the same size spanner but instead they did the difficult work (two different nuts on the same sized thread and adding one more different part ). Thanks Honda!
