If you look for 7/8" handlebars (22mm) online, most are "just the bar", meaning they have no dimples or holes to set your throttle control housing index pin into. You could drill a hole into the bar after lining up the throttle controls to your liking. Others will take a dremel or file and cut off or file down the index pin (the plastic nub on the throttle controls that fits into a hole in the handlebar to prevent it from spinning or rotating on the bar). This would allow you to simply slide the control onto the bar without making any holes in the bar. Some people argue that making a hole in the bar weakens it. However, if you file off the plastic index pin, then what is to stop the control from rotating around on the bar? For this, you could wrap where the control clamps into the bar with electrical tape, or a double sided type tape, so that it will make the bar "sticky" at the spot you choose to mount your throttle control housing.
I can say from experience that if you choose to buy a non-OEM handlebar to replace your bent one, you can choose any number of bar ends to fit the bar. Its been mentioned on this forum that A/M bars do not allow the OEM bar ends to be reused. Anytime I've changed handlebars on any of the bikes I've owned (my wrists like very little sweep in a bar), I've used A/M bar ends without issue. You can choose from many colors, styles, and materials if you do. I use vibration dampening bar ends just to add a little more comfort for my longer rides.
For reference, this is the dampener I use (which won't work on OEM bars, but does on most A/M bars). They do require using the included tap to thread the female end of the handlebar. Visit bestdualsportbikes.com for more info if interested.
Just another option. Good luck with your handlebar job.
