Bike in question 03 softail standard , hoping for some affordable recmmendations for seat models w the dual back rests thanks guy.

 

I put a kyryakan ( whatever the spelling) drivers detachable driver backrest on mine. You can find them for about 130-175 on eBay sometimes. Work with the few seats I have and is very good on my back. Work great for long rides. Really wanted something that works with all my seats. Only use it for long rides and the hardware left on the bike doesn't look bad when it's not in use.

 

there are no holes in the current seat so , as far as I know I have to replace the entire seat .

 

I bought a used (only 2100 miles) Mustang w/drivers backrest on Ebay for $215. Put a passenger backrest on it as well and everyone was happy
