I used one just like that on my old VF700F which has square tubes (although they're steel and about the size of round tubes). I think that although it works it would be better to take the stock style lock, for instance the on that was originally on this bike was built into a bar I removed when I changed out the turn signals, and build a custom aluminium plate to hold it. I know that would be a bit of work, but I just don't trust that little lock that much, and when you have several hundred dollars tied up in your brain pan what's a little hand laid machining? on the upside the lock comes with one way screws, so if you could use the stock screws it would be hard for someone to remove them. The problem I ran into was that the stock length screws were too short when using the square tubing.
