I bought an inexpensive set of Fly aluminum bars, only to find they bend just as easily as the stock bars did...
...until, I bought a set of aluminum barkbusters! They really added a lot of strength to those bars. I've hit trees, stumps, boulders and plain old hard pan dirt, going at pretty good speeds without doing very much damage at all to the bars.
Sure, I've tweaked 'em some. What can you expect when you clip a tree wide open in third gear? :eek:
For grips, I use OURY grips. They are nice and cushy!
I bought the Pro Taper barkbusters used, I found 'em on ebay for under $20
I also use Fasst Anti-Vibration Bar Inserts
