2013 versus 2014 wheel size

[tod.branko_imp]

Reducing the axel OD increases the bearing ID, unless the OD of the bearing was reduced also. A larger ID bearing should increase the service life of the bearings.

Did you mean to say "Reducing the axel OD, reduces the Bearing ID"? Small Shaft OD = small Bearing ID. If the Bearing OD remains the same as previous with the larger Shaft, then the Bearing Balls increase in diameter for the smaller Shaft. This in theory would increase service life expectancy. I may be misunderstanding what you're meaning Dave...?

I may be misunderstanding what you're meaning Dave...? That does make sense. Still, as you mentioned in your first reply, it probably has no noticable effect on flex at all. Can we confirm that the bearings have the same OD between 2013 and 2014? In that case wheels are probably interchangeable with a swap of bearings regardless of the shaft size? Unless the issue is in the size of opening in the swingarm itself
