Product: Krator SMI5050 Light (Motorcycle Curved Vertical Mount License Plate Holder Black Billet Tag 1&quot; Axle)
Overall sentiment: negative
Customer reviews:
Cheap and thin. Filmsy metal sheet kept on the bracket with 3 simple welding spots. The vibrations are going to break it soon. Also, most axle nuts have a much smaller diameter, this is too large. Holes are not the same measurement for New York State plates. 
 had this on my bike for about 2 months before it broke off.  Poor Quality, made of thin aluminum.  I have since replaced it with a steel bracket that is much stronger. 
 Was a loose fit when installed and had to bend it way out to keep it away from my belt pulley and guard. Had to drill a hole and run a chain from my saddlebag bars to keep it from slipping straight vertical down. 
 UPDATE: 1200 miles after install.  Arm broke off somewhere down the road.  Now I have to get a new license plate, new tag and mount.

The armature is too weak to support any forces from wind.  It has tac welds which for now are holding up after 500 miles, but the arm has bent sideways from wind pressure at highway speeds.  If arm could be shortened or reinforced it would be a perfect buy. 
 Undamaged out the box but is as flimsy as other reviews say. I didn't bother installing because of it being so flimsy with only three tack welds holding the two pieces together so I can't say anything as far as functionality goes. IF they use thicker gauge metal and/or improve welds it could be ready to go out of the box. If not you should expect to modify this plate holder before installing. 
 Thin with crapy welds and would not fit without being modified. 
 I have a 2013 Harley Davidson Street BOB and does not fit. Quality does seem flimsy as some stated but I think it would hold up fine. 
 Found out illegal in my state after installing them on 2 bikes 
 This will work with a sportster. If you put it on a Dyna, you have to put it on the pipe side, the curved plate mount will hit the belt wheel on the other side. The Aluminum is VERY THIN and shakes like crazy. I added a thicker piece of aluminum to the strut to make it shake less but it STILL goes crazy. 
 This is ok for the money but it is what it is. I got it just to move my license plate and it works fine. does not vibrate at 80mph. 
 Purchased for my zx-6r. Looks okay when the bike is parked. But vibrated a lot when the bike is in idle. Horrible.
