My riding buddy had a DG. He popped a tree with it and it both bent and snapped off a bolt. The DG definitely sticks out further from the bike than the AC does.
Bumpers are a matter of opinion, as to which one you think looks best. I like the looks of the AC, even though I am not a real fan of AC products. I guess I should clarify that and say that it is their skid plates that I am not fond of. Later.

The Duncan Racing front bumper on the 400EX is the best. Everyone and their dog has either a DG, AC (if you can get one),or a Graydon. Step up, be different, go first class get the DR bumper. The only thing to remember when purchasing add on's or mods is "Its only money!".

 

You should check, the one of Extreme Fabrication, is like the AC, but a lot cheaper.

I like it more than the AC.

 

in a head on collision with a tree they dont bend. My buddy fell off his 400ex at full throttle and it went into a tree and broke all the welds right off the front bumper.

 

I have an AC with mud screen, but if you want something different check out
