I've used SW Motech center stands, 3 of them, with no complaints, but the Happy Trails stands are notably less expensive so I thought I'd give one a try. I placed an order online and received a shipping date about 4 weeks away, with an explanation for pandemic-related delays. About 5 weeks after placing my order, I had the stand in my hands.
It comes pre-assembled and the first photo shows how it comes out of the box. The instructions were not the best but the procedure seemed pretty self explanatory.
The bracket shown in the second photo is the mounting point. The top and bottom holes are threaded. Clear the threads in those holes before proceeding. There's factory paint and grease and debris on them and the mounting bolts can't wait to jamb in the threads. I didn't do a very good job of this and suffered accordingly.
The factory instructions have you begin installation on the left side of the bike. Those two bolts are simple. The upper bolt on the right side is a bastard to access because of the exhaust. If I had a 6mm Allen in a 10" extension this job would have been easier. In the end, I tightened the 3 installed bolts while lining up the stand with the bracket so that top bolt could be fed on the end of my 7" Allen key through the obstructions into the hole.
The instructions emphasize that the stand is not meant to be used with someone sitting on the bike - it isn't a ride-off stand. The long lever on the side makes it relatively easy to deploy the stand and the back wheel sit high enough to spin freely. The stand has been on the bike for just a few days so I can't speak to it's durability.
