Lamonster F3 rider backrest.
Easy installation, plenty of adjustability, so much more comfortable on the long rides. Just wondering why I took so long to purchase such a great product. Thank you to everyone on the lamonster team.

Driver backrest for 2021 F3ltd
Excellent backrest and a great mounting bracket. Easy installation. I would like to see a rubber boot covering the whole top of the bracket to protect the rear seat more from rubbing.

Clean Look
Looks High End and installs very easily...I used it to go from VA to Daytona Beach and back. It was awesome and could be adjusted while riding... Lamonster backrest is perfect.

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.

Back rest F3
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!
