Post by: Jordan1200 on January 05, 2019, 05:16:53 AM

The two cams listed are stock 103 cams, front and rear. The SE 255 is PT # 25638-07 and sold as a pair

I'd read the CVO 110 motor had a 255 cam and therefore thought the cam in my 2015 FLTRUSE was a SE-255. Had a Stage II upgrade to a SE-585 performed and noticed the take-off cam was stamped CVO-255. Looking to offer it for sale and need to know what bikes it will fit.

Oddly, the SE-255 (P&A #25638-07) appears to indicate a fit for 09-13 twin cam motors which suggests the CVO-255 from my 2015 must not be the same as the SE-255. Seems as though the CVO-255 ought to fit twin cam motors 09-16, am I wrong :nixweiss:?!?

Those 255s will bolt in 06 and later Dyna models, 07-16 Touring, and 07-17 Softails.

The SE catalog indicates fitment for 2007 and up Twin Cams, not 2009-2013.  And the stamp on your cams (CVO-255) I  believe is just an assembly aid for the engine plant, to make it easy to verify the correct cams were installed.  If you look up the cams in the Harley parts catalog for a 110 CVO you will find the 25638-07 part number, same as the cams in the SE catalog.  If someone with a bone stock 96 or 103 wants to install those cams, they will need to verify the rest of their valve train is compatible and will most likely need to also install compression releases.  But the short answer to your question is yes, those cams could be used by people with any 2007 and up Twin Cam version.  They won't fit earlier models due to the change in the inner cam bearing diameter for 2007 as well as the outer cam bearings in the cam plate, at least without some modifications.
