they aren't very strong. i bent mine very easily (although i was riding rigid). but, i emailed Mike and told him about the situation and he was willing to give me 50% off on any of his other bars. luckily i already got a hook up on the LTD's so it wasn't a huge deal.
nope didn't crash even once with them..just rode street with them for a little less then 2 weeks and bent them downward a little. then, i took them onto the dirt once and bent the crap out of them. i weigh about 175 on average and i'm not a hack.
here's what they looked like after a few runs on the dirt. they were about twice as bad after the day
