Lamonster Ultimate F3 Rider Backrest
Another quality product from Lamonster. Very easy install. Took about 20 min. I ride at position #3 and am very comfortable with the rest all the way forward and in it's lowest position.

Wow what a difference this makes. Wasn't sure it would make that big of a difference. It does. Installation was good, when I followed the video. Paper instruction weren't near as clear. Highly recommend this product.

LAMONSTER ULTIMATE F3 RIDER BACKREST (BLACK STITCHING)
Easy to install, great fit, adds much comfort to the ride. Installation on my 18 LTD was not exactly per instructions - Step 5, I had to reuse the OEM single screw as the new M6 x 1" did not fit the tap, and Step 6, I had to remove the black cable hook (instructions say "F3T model only.") This is all minor stuff for me, I am very pleased wit the results!

I purchased this item several weeks ago and have put at least a few hundred miles on it. So far it's met the mark. Great price and it works. What more can you ask for.

I purchased and installed both the rider and passenger backrests together. They appear to be great quality and installation was easy and straight forward. Thanks Lamont for another great product!
