I flipped my Warrior down a hill yesterday and bent the heck out of my handlebars, light bracket, and not to mention ruined a new paintjob. Will the bars and light bracket still be strong if I bend them back. they aren't the original bars, they're off of a dirtbike.

 

will they hold up to you just riding around? Sure...

Since it's a warrior, I doubt you'll be jumping large jumps any time soon. They are obviously going to be weaker at the newly created stress spots... but unless you put a major crease in them, you'll be fine.

 

On my bikes - bent a little (an inch or so), put a pipe on the end a bend it back. If it happens again, I trash'em. Or if it is really bent (a couple inches), I trash those too. Better safe than sorry. Handlebars are inexpensive. I few riders in my group have had half of a handlebar come off while riding (due to overstress).
