If you run a full rally setup theres a couple of kgs up high where you don't want it pulling at the bars.
But if you are running a Acerbis type rb-holder and a Vector there is no need imho.
I've run lots and lots of rally routes with a handlebar-mounted setup. I don't notice the extra weight on the bars much. Generally, a handlebar-mounted setup will be lighter and simpler than a frame-mounted setup. So, that means a lighter bike overall, which is never bad. Mostly, I'm too cheap and lazy to build a frame-mounted setup for my XR, and I don't see any real need to. If I were to run another big rally, I'd take the XR with handlebar clamps, F2R, and one ICO. We ran 8 bikes with this setup in our last Rally School without a hitch. In my book, simpler is better. (And, when others are prepping their bikes, you can be out riding.)
