I always liked the look of the "103" derby cover on my old '11 Street Glide. My current ride, a 2015 Ultra Limited has a plain derby cover. I would like to put a "103" one on my Limited. I am thinking that it will work fine. Am I correct?

 

Should be easy enough to go out on the HD corporate website and access the online P&A catalog, that will tell you what you need to know.

 

It'll fit. The only time there would be a problem is going from TC to M8, the primaries are different.

 

twin cam derby covers will work. where you will come into problems is the narrow primary uses a bigger derby cover. so a regular primary derby cover is not interchangeable with the narrow and vice versa.

 

Didn't all the '16 model touring bikes have the narrow primary cover?

 

I have a 103 derby cover Im not using. The chrome isnt flawless but its not too bad. I can post some pics when I get home. Where are u located? Gilbert, AZ here.

 

probably so, but the op is talking about the derby covers from 2011 and 2015.

 

Your stock plain derby cover is #60766-06, which indicates it was introduced in 2006, so any alternative from '06 to '15 should be just fine!

 

Your 2015 could have either narrow primary or the old standard wide primary. Most likely it is a wide. Covers are a different size If cover is 8 inches you have a narrow if it is smaller you have a wide. Just get the right one.
2016 and up Tour have the narrow, some 2015 had the narrow also. they put the narrow on many of the Low models.

 

and some people have put the narrow primary on their 'older' bikes (like me )
