Replacement TRX 400EX Handlebars

I bent the heck out of the stock handle bars on my 2005 TRX400EX.

Looking at a parts fiche, I see bar weights are used. I have two questions,

1) Are the bar end weights really needed?

2) Other than Honda $71.00 plus freight. Who makes a replacement handle bar and, will it also require bar weights? I’m looking for O.E.M. quality, nothing fancy.
