This one looks pretty cool. I like that bar at the top going around the front, would be a good place to hang some lights.
That's true, but I think hanging lights is about all it's good for.
IMO if you're looking for actual protection higher up, you really need to secure it to the frame somewhere high up (de-coupled through some rubber pieces of course so you don't damage your frame during a drop), or have some stiff rubber or larger surface area metal with rubber between the guard and the tank to prevent the crash bars from becoming damage multipliers.
I really just don't like the round-tube-an-inch-from-the-tank design because in a drop, that bar will just bend right into the tank. If you can spread out the force of the bar hitting the tank with some rubber, or by also adding a wider metal piece to the inside of the bars to spread out the force it would put on the tank.
Actually, now looking at it closer, maybe I am missing one of the mounting points on this design. Does it connect to the front subframe via that upper front bar? I don't think that the sub-frame would be a good place to secure it if you're expecting to crash on it (that would just multiply damage I think).
The only mounting point appears to be the 2 bolts right above the water pump. That can't be right can it? If that's the case, then it isn't supportive at all...
