Got my Firehouse Customs backrest today for an 08 Heritage.
Putting it on is a breeze. Pop the passenger pillon, unscrew the seat, put the backrest on and put it back together. 2 minutes and done. I got the studded rest, fit and finish is good and it goes with bike well.
My concern was if the backrest was going to push me up closer to the bars. But to my surprise, it took no seat space away. I'm about 6' 1" and just over 200 lbs. The support has enough spring in it so you can keep upright, but kick back a little. When I kicked my feet up on the hwy pegs, I settled in nicely. Big improvement over no rest at all and has made my Heritage MUCH more comfy.
All in all it looks like it should hold up well. Will keep an eye on the seat screws that hold it in, make sure they don't get loose but...probably a better $173 ($155 for backrest, $18 for shipping) that I've spent recently.
Oh, and I ordered it on late wednesday night (3/18). I was emailed on Friday (3/20) that it was shipped and I got it Saturday morning (3/21).
If anyone would like, I'll post pics when I get em.
