After rolling my Banshee this past summer I bent my Handle bars and my Upper A-Arm. This stopped me from riding for about 2 weeks, so I had enough I wanted the toughest handle bars I could buy. I did a lot of research to see what there was out there most was a double wall with a support across the middle. Then I saw the Renthal Fat Bar. I was sold.

Here is what it says on the Renthal web site "Renthal FatBar® handlebars are designed with a 5.0 mm wall thickness at the bends to add strength. FatBars® have a shot-peened anodized corrosion-resistant finish and feature a laser etched positioning grid. FatBar® handlebars are used and endorsed by: Team Shark/Plano Honda, Blackfoot Honda, John Dowd, Fred Andrews, Denny Stephenson and Paul Edmonson."

Not only does it feel like the handle bars won't bend, but I noticed that there was less vibration in the grips. The laser grid helps when positioning the handle bars to where you like it. The down fall to the handle bars is you will need to get a conversion kit or do what I did and get a Roll design Steering stem and IMS clamps. The way I went was a lot more money but in the long run I think it is worth it if you plan on getting an aftermarket steering stem.

if the handle bars dont bend/break, then something more expensive/important WILL , id rather break my bars and throw on some new $18 moose ones, than have to stop riding for the day and go dish out a bunch of cash for a new steering stem
wtf does bending an a-arm have to do with having tough bars?

edit - clicked on product reviews, had no idea this was from 2005, oops

why buy a new steering stem? just whip out the torch and bend it back
