Wheel bearings
Too Bad that Harley moved away from tapered bearings
ball bearings can take about 1/8 of load
25/52/18 abs ball bearings fatique load limit is 63kg Or so, while tapered of spherical roller bearings are over 400kg
if I just could find spherical with ABS compatible
Would change those as next bearings.
fatigue load limit explained.

In lbs
Those bearings can take ~150 lbs each that is 300 lbs front and 600 lbs rear before start wearing out, that is bike Weight only
tapered (angled roller) bearings can take ~1000 lbs each
Any extra like driver and wearing starts hapening
Not Even meant to last long, there are better ways
For abs sensor than one on bearings, but More $
from Spares on that way

Time
Well If I did not calculate wrong at 60MPH wheel rotates
about 800-1000 rounds per minute, typically bearings are specsed much higher rpm, If bearing fails at 18k Miles that is 300 hours at average 60mph
While I work bearings go for 5000 -7000rpm and get changed mayby once/year. Well If we divide that 300hours by 5x more rpm we would need to change
bearings twice a week every 60hrs or so...
So My opinion 300-500 hours bearing lifespan is abysmal
Well same is true almost all heavy touring bike today
Just My 2c
