Engineering excellence: InfiniPack system and Smart Storage
At the heart of the EXR lies Radian’s innovative InfiniPack battery system. Designed for quick, ergonomic swaps, the curved packs maintain the bike’s center of gravity, enhancing performance. It debuts with an 8.6 kWh Endurance battery, providing 60 to 115 kilometers of range per charge depending on the course and riding intensity. A lighter 5.8 kWh Sprint pack will soon cut the motorcycle’s weight from 125 to 113 kilograms.
The EXR’s drivetrain features a 336-volt electric motor with a carbon-sleeved rotor and specialized inverter technology, delivering 1060 Nm of torque directly to the rear wheel. The system fuses speed and simplicity, revving up to 14,000 RPM without a traditional gearbox, allowing seamless gear-free rides across technical terrains.
Furthermore, Radian’s approach to storage is revolutionary. The Smart Storage system, integrated directly into the bike’s aluminum subframe, eliminates the need for cumbersome backpacks. Modular compartments can carry varying equipment: tools, spare parts, chargers, or even custom inserts created through 3D-printable files offered by Radian.
Visual and technological impact
The EXR’s aesthetic is raw and industrial, favoring functionality and minimalism with exposed fasteners, ribbed bodywork, and fluid lines. The animated Radian Vision LED headlight not only lights the way but communicates charging status. Premium features such as KYB suspension and Brembo brakes are standard, ensuring top-tier performance.
The limited Founders Edition of the EXR adds exclusivity with Haan wheels featuring Excel A60 rims. This motorcycle is designed to reduce distractions during intense enduro competitions, integrating enduro-specific features like built-in timekeeping systems and minimalist controls.
Roots in racing and development trajectory
Radian’s innovation is anchored in its heritage. Founded in 2021 in Twente, the company draws on experiences from the Electric Superbike Twente initiative, which dominated the 2018 MotoE championship. Radian collaborates with prestigious institutions such as the University of Twente and the Fraunhofer Innovation Platform for Advanced Manufacturing, as it seeks to revolutionize the off-road electric motorcycle market, with plans that extend into motocross and supermoto categories.
The EXR’s design and engineering place it at the forefront of electric motorcycle technology, with features that position it well for a successful launch in 2027.
