Well, this was on a 650, not a 400, and I can't find the mileage, but let's say somewhere between 20,000 and 30,000 miles:How often is replacement interval ?
Buying OE or match at bearing house ?

Is my MPH to RPM normal for 2006 AN400 ?
But wouldn't mind lowering Hiway RPM. Understand the Dr Pulley 21g sliders might help achieve this goal. In your quest to lower RPMs, don’t forget that peak power is up around 7500 rpm
After that, I had the shop replace bearings about every other tire change.
