So the ones I've come across are 49mm long, 49mm short, and 41mm......for some reason JPcycles says that 41mm gaiters will fit a 14 SB. What size do I need, and does anyone have any suggestions on cheap alternatives (dirtbike gaiters) that would work? I'm looking cheap cause I plan on just cutting them and using zipties.

 

Check Ebay. I have seen a few of the split style that don't require cutting on there in 49mm

 

49mm. And like fordaith said, the do make some that are split already so you don't have to pull the forks.

 

Read my post, you do not need to pull forks for installation, use silicon spray and slide them through. 49mm any mid glide front end. https://www.hdforums.com/forum/dyna-glide-models/693241-street-bob-fork-boots-installed-w-pictures.html

 

I got a pair and have been debating splitting them also

 

I can't seem to find any 49mm pre split ones on ebay. I may just go with that set from jpcycles that 128auto posted up.

 

Get only JP cycle 220-535 boots, they are made in Japan good quality rubber like condom .

 

i got mine at southeast customs, but they're not presplit ones. But they were really easy to put on. Only took me and a buddy about an hour to do.
