They're just handle bars,not a stressed suspension component. There's really not a whole lot of load on them. :twocents:
You ever ride with a bunch of sportbike riders that have clipons? Most of those squids lean on the bars lock arm like their life depends on the strength of those tubes of metal... and then complain of wrist pain. :nuts:
I personally wouldn't drill holes in any set of bars myself as a little strip of super fine skateboard grip tape keeps my controls from moving about, never liked even a shallow hole in my bars, if they are bent, toss 'em in the bin for the dirtbikes! Can't stand the thought of a handlebar failure. Had one of those a few years back and can't bear the thought of it again.
The left bar on those cunts decided to go parallel with wheel direction during a standup wheelie and I found myself landing one of the oddest wheelies you have ever seen in your entire existence, at 50+mph. The mere hint of a chance for bars to turn sideways while the forks are strait, although it took really reefing on the damn things to make it do it, I had done at least 50 wheelies the exact same way before the failure, it made me cautious of how much I modify equipment even if it doesn't seem like much, if OEM stuff can fail like that, I don't to see what garage modified bits will do when they come apart all wrong... then again I have a pretty extensive list of those experiences too.
Never mind me, drill all the holes you want.
