Ordered mine on turkey day and it arrived today. Need to put new rubber on the bike this spring, so it will probably be a while before I install it. In regards to the weight question, I put just the permanent portion of the lock unit on my digital scale and it was going between 2 & 2.5 pounds. My guess would be after removing the stock bracket and installing this you are only adding at most 2 pounds of unsprung weight to the rear of the bike. When I install it I will weigh the stock bracket and post unless someone else does first. Thanks for posting the link for purchasing, now if Icould just get one for my wife's FZ6R for on $30 shipped.
