Kalk is intended for off-road use and features components specially developed for this purpose. Weighing only 67 kg, the electric motorcycle comes with an engine within a frame made of screwed aluminium profiles, at a position where conventionally powered bikes have the gearbox. From the cockpit, three riding modes can be selected without a clutch or shifting. Thanks to its digital presets, beginners and professionals can easily ride the bike at their own level.
