The stock hand guards on my 2014 KTM 500exc (that were newly desighned for 2014) broke off the first time I fell on the bike. I am happy to report that the Acerbis X-force Handguards can take a beating. I had 5 hard falls on my last 90 mile ride and the hand guards are still on the bike. The way they mount to the handle bar allow the guards to flex on impact and not break. Also, the material they build the mounts out of is not brittle like the stock hand guards. Great product for the price!
