Super simple

I didn't think that a 2" drop was a lot. <br />But after installation, I felt like my 72 was dragging on the ground. And it looks good too.<br />Just what I was looking for .

Great product

This is exactly what I was after. Directly after installing, Curious of other peoples claim to "bottoming out", I intentionally seeked a bumpy uneven road. Nothing negative to say of that ride. Definitely stiffer then stock but you have to take into consideration the 2" travel loss. Feels "sportier".The only reason I 3 stared Install is because I bought a "complete kit" for a 2015 sportster and the directions did not have what length the front spacers needed to be cut at. A quick call to burley and I got all the info I needed.

Installed on my 2014 Sportster 883 Iron. Fit is amazing, easy to install, helped me fit the bike tremendously. The only con, and only reason for 4* as apposed to 5* is that the stock exhaust doesn't have good ground clearance for right hand turns after this part is installed.
