Hello, Sorry I do not know anything about softails. My brother has a 2016 FatboyS with the train light nacelle. I have a Road King S. I want to give him my Carlinis with riser as a gift, but not sure if it will fit.
Please see pics ...
If it wont work, can anyone point me to the proper riser? Im pretty sure it fits under the Nacelle like my road king, but not sure. I have not seen him or the bike in a year..

 

Wish I could help , sure someone will on this forum , but those are 2 NICE looking bikes

 

This is very frustrating ... The HD website says the Train Nacelle does not fit on the 2016 FatboyS or just Fatboy even though you can see it installed on my brothers bike above. Also, I remember back in 16 when it was new, the Nacelle was a popular option that I wanted. I almost bought the same bike new and I priced it out with the Nacelle and Apes.
I am sure my RK riser will not fit, I just need to find the riser that will accept 1.25" bars under the Nacelle.

 

Yes the Nacelle fits. Had it on my Slim. It is a two piece riser that fits under the Nacelle cover. Cant remember the part number, but I know it is in the Softail parts section on their website. And yes, I do recall the site claiming it did not fit.
