2013 versus 2014 wheel size - Houtman_imp - 10-06-2021

I just put a set of brand new 2013 wheel for sale , I know that one of them is the same as the 2014 size and think that it is the front rim but I am not 100 % certain. I think that the 2014 has a different rear axle diameter . Anyone knows ?

US Models, maybe other countries:

2013 rear axle is 25mm.

2014 & 2017 are 20mm.

To be sure, what size is yours?

I wonder what the technical reason for lowering the diameter from 2013 to 2014? Was the 2013 "over-engineered"?

The axle on my 2013 rear is 25 mm and therefore would not fit on a 2014 .

That's a darn good question for the engineers (or bean counters). I can't imagine any real-world drawbacks - many Hondas use a 25mm axle, like the VTX1300 series. Yet oddly enough, the heavier, more powerful VTX1800 series introduced at the same time, has a 20mm axle.

The engineers did say why they did it in one of the engineering talks Honda posted. They said it would flex more and give a better ride. My question is: How much does an axle flex?

Ya, weird. How much would a little stubby axle flex relative to the tire alone?

The CAD mechanical stress simulator must have told them so. Undecided

Hmm...I call BS on the flex concept from Honda. If you look at where the Axel passes through the Swingarm and consider how close the adjacent Bearings are, the Axel has very little opportunity to flex. The Axel is nearly in sheer at the Bearing/Swingarm intersection, with nearly no unsupported distance allowing flex to occur. Regardless, if one considers the strength of material and the design configuration coupled with suspension designed to allow wheel movement, there is just not enough opposing/resisting force provided above the wheel to generate Axel flex. Ignoring all of that, if the Axel did flex, you're talking about flex measuring in thousands of an inch. Would take one seriously sensitive bum to discern that flex and perceive it as reduced harshness in ride.

Most likely answer is there was an economic reason to do so, which is fine. As long as it doesn't compromise performance, design integrity or safety, go for it.

Thank for the explanation Phadreus. That makes sense to me.
