I have a 2011 YZ450, and Im doing some shopping for handguards/bark busters. My handlebars are pro tapers, not sure on the model, but at the end of the bars, they look to be 7/8", but towards the bar clamps, the bar becomes oval in shape, and I'm having a hard time finding handguards with clamps that fit that oval shape. Can anyone point me in the right direction on finding handguards that fit this bar? Note: not looking for roost guards, I'm looking for the full aluminum handguards. Thanks!
