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...? 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(10-07-2021, 02:47 AM)Phadreus_imp Wrote:Did you mean to say "Reducing the axel OD, reduces the Bearing ID"?

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.

'14 CB1100 STD 5 speed
'14 CB1100 STD 5 speed The right side bearings are both 52mm OD, and the left side bearings are both 47mm OD. But the 2013 uses TWO bearings side-by-side, a combined width of 24mm, and the 2014's single bearing is only 14mm wide.
There are no bearing(s) that have the particular dimensions needed, so a 47mm x 10mm ring spacer needs to be pressed in, and a 10mm longer bearing spacer needs to be machined. The sprocket carrier uses the same bearings, but different spacers, and swingarm axle adjusters will need to be changed.
Doable, just not a bolt-in.
