Is someboy out who replaced the stock springer seat by an bare bone,... or similar one?
Which mods are necessary? Thanks

 

A friend of mine replaced the stock seat with a Brawler seat and pillion pad.

 

i have the Brawler, too...

just take the seat off...the mounting brackets...plastic cover...

you'll need to buy a seat nut(comes with plastic c-clip)...had the wife, with her smaller arms, reach up under the fender with the nut...

a couple of the electrical plugs were attached to the rear spring bracket...i just zip tied them to the frame

 

I have a Mammoth Sloth... Like XKAVATOR said pretty simple. I used a large tie wrap and threaded the nut on for the seat bolt then just treaded through the hole in the fender pulled up the nut and snapped the lock ring on..
