If you’re like me, brake and clutch levers are consumable. But the availability for replacements are limited (for now). KTM clutch (p/n 63502040000, €60) and brake (p/n 63513002044, €55) levers are ok, but better controls do exists.
Watch out for the Chinese knock off on ebay or other. People have ordered parts and they never shipped, and some received 790 Duke parts (they are different, the Duke has a hydraulic clutch).
A shorter clutch lever, activated with two fingers, is harder to pull than a full sized one of course. Short or long, Camel ADV made a small little gadget making the clutch course longer and diminishing the effort at the lever. It’s called the One Finger Clutch.
