This is a very good quality made bar. Install in made easy with the flag-nuts and bolts. I bought the add on bar to make it able to haul three bikes at once. I use it for a 2012 kx250f, a 2001 yz250f and a 2012 Suzuki rmz450. I have never had any bikes move or bump into each other using this bar. I also use it to haul two gsxr600s and have no problems. Without this bar I am sure my bed would be bent into the cab of my truck. They only downside to this bar is the black powder coat fades from the sun pretty quick.
