Great Backrest, mounting bolt marginal
I installed the backrest on my F3 Limited last night and very straightforward. Only problem is the torx head on the bolt on the back portion of the bracket stripped rather easily so ended up re-using the stock bolt. Other than that, the backrest is very high quality and makes for a comfortable ride.

F3 Backrest - Excellent Product
We purchased 2 of these bzckredts for both our F3's. The website was very easy to navigate and order. The shipment arrived in just a few days. Watched Lamont's installation video. Installed both in a total of about 25 minutes. Rode today for the 1st with the new backrest. Great product and makes a huge difference. Highly recommend this product. Thanks Lamonster Garage!

Picked up one of these for my F3s. I’ve owned an ultimate seat and backrest in the past. Great quality. I was so glad that Lamonster Garage was carrying these and his install video was top notch and made it so easy.
