Kalk OR
The focus here has been off-road performance and innovation.
As there wasn’t anything off-the shelf to support the category, every single component had to be developed from an empty sheet, to support the intended level of quality and durability:
The sizing, the geometry and engineering of axles, hubs, rims, the cockpit and suspension, as well as building and customising the different parts of the drivetrain, together with developing a whole new chassis; having led to numerous patent pendings, constitutes the introduction of a new category, the Light Electric Off Road Motorbikes (L.E.Os). Please note that Kalk is developed for off-road use only.
The suspension is specifically developed, by Öhlins supporting the category of hi performance at minimum weight. Nothing has been left aside and every part including axles, hubs, cockpit, sprockets and even the tires (to minimise wear and footprint of trails being used), have been explicitly designed and engineered for the ultimate experience. The light and snappy ride, with its focus on off and on trail riding, in the outback, means that its main character is about torque and acceleration, while providing a quiet gliding and surfy experience. Thanks to its digital pre setting, serving for 3 different riding modes, it will let anyone fly at their own level.
“The level of precision and detailing is beyond anything I have seen. It’s a gem”
Fredrik Moberg, the very first owner of Kalk limited Edition.
