Kalk INK race

Kalk OR race and Kalk INK race are a power to weight ratio optimization pursuit, building a chassis, as light and lively as possible, around the electric drivetrain, in contrast to the normal procedure, merely swapping from combustion to electric, in a gasoline chassis (extremely heavy).

The inspiration comes from the first enduro competition a Kalk attended. A brilliant result combined with the demand for knobby tires.

Important to understand despite the good results vs traditional dirtbikes; the Kalk, with or without the race kit, is not engineered to imitate or to compete against combustion engine dirt bikes.
The Kalk is a first step establishing a new category of motorbikes, designed for a new user matrix.
It’s about building light, quiet and clean, easy to ride, low maintenance, super nimble, never buying gas or filters, high performance, ride without disturbing or polluting. Exploring new areas with respect.

More information about the race:
The Gotland Enduro Championship, the first race for a Kalk OR. CAKE friend and Yamaha team rider (when on gasoline) @robertkvarnstrom managed to accomplish an impressive result and shared a massive boost for everyone supporting the electric revolution.

- Heat Winner
- Winner of the electric class
- 5th fastest time, 5 laps VS. all classes pro to amateurs (118 gasoline participants)

First out on the track, the only option was to compete in the electric discipline together with all smaller classes, meaning tons of riders on the track and continuous overtakes from Robert, having to shout out loud at slower riders who didn’t hear him coming. Unfortunately, the track became faster later during the day. Robert and his CAKE was exceptionally fast during the technical parts and went well on the big open meadows.
Design and engineering:
The Kalk is engineered around the electric drivetrain to maximize the riding performance. The electric drive train are completely different from an internal combustion engine, with benefits for each side. An electric drivetrain includes a solid battery, electric motor and a controller, and features instant torque from zero, direct drive, no need for a clutch, few moving parts, low tinkering, no fumes, no sounds, no filters, no oils, tuneable riding modes and regen breaking, responsive and great throttle control and swappable batteries.

All parts and components are developed from scratch to keep the weight down at with highest possible performance. Everything from the rims, hubs, stems to the custom Öhlinssuspension (Kalk OR) is engineered and dimensioned, specific for the Kalk and the new category; lightweight electric motorbikes. The components are in a new category and derive from the most sophisticated DH components in terms of technology, materials and manufacturing, but heavily reinforced, rather than downscaled MX components.
Standard DH parts are engineered for DH bicycles, and become too weak. On the other end, MX components, developed for the user matrix on a dirtbike, simply become too heavy to.

Building light electric, uncompromising motorbikes for the ultimate off-road experience requires components, engineered for it.
Combining off-the-shelf parts MTB and motorbike world, would result in increased amount of parts, bolts, tinkering, welds, impaired geometry and riding experience. As mentioned, the MTB components are too weak for a 69+kg (Kalk OR) motorbike and the MX parts, too heavy, not serving for the specifics of the electric drivetrain.
Same thing goes for traditionally designed electric dirtbikes, engineered and optimized for a combustion engine, where the ICE (internal combustion engine) is simply swapped for an electric drivetrain, not particularly efficient.
