Which type of cam bearings are original equipment from the factiory on 2015 CVO 110 engines?  I hag heard that  they to roller bearings in 2014 but I am not sure,

They changed to a better and higher capacity needle bearing for the inner cam bearings starting with the 2013 engines.  The part number listed for 2013 - current CVO110 engines is 24018-10 Bearing Kit, needle.  You will hear them called either Torrington style or full complement, as compared to the cheaper and lower capacity needle bearings previously used.  Btw, a needle bearing is a roller bearing, just with tiny rollers.

The outer cam journals don't ride on ball or roller bearings since 2007, they just ride on the aluminum of the cam plate with a thin film of oil between the parts.

I'm curious on what the conventional wisdom is on changing the inner cam bearings when doing cam swap on a relatively low mileage engine (2015 CVO 110), say less than 5K miles. Since the engine is reported to have the better needle bearings in there now would a change be necessary, unless its a "wear in together" thing with the new cam.

Also, do the bearing removal/insertion tools for a 96/103 engine work for the 110? (showing my lack of knowledge a bit)

Thanks,

the tool will work. Id change them while your at it. They are not expensive. Numbers facing away from crank

My thought is that the cam shaft is the inner race, and they are cheap.  S&S cams provide the cam install kit when you buy their cams.  I also believe in changing lifters with cams, but that is probably a different topic.
