I ran Acerbis Rally Pro's. They are typical acerbis plastic style, with a metal bark buster inside. The best of both worlds in my book. Handguard protection, bark-buster strength. I did not need to change my levers at all, but KTM levers may be a bit smaller or something. My only problem was if I would go down and bend one, it was stuck bent...one nice thing about Acerbis Rally's....they are all plastic and are movable without tools if you pound really hard.
