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 radial master cylinder).

Someone on facebook made another longer clutch extender, no idea of availability or cost:
