EXR electric enduro motorcycle by radian swaps batteries in under 30 seconds

Radian introduces the EXR, a competition-ready electric enduro motorcycle built to challenge combustion-powered racing across off-road disciplines. The drivetrain delivers 70 horsepower and 1060 Nm of torque to the rear wheel from standstill, using a 336-volt motor, carbon-sleeved rotor, and proprietary inverter technology. The motor revs continuously to 14,000 RPM without a conventional gearbox, enabling gearless control through technical terrain. A patent-pending battery-swapping system replaces depleted packs in under 30 seconds without tools. The curved InfiniPack slides through rotational motion to keep rotating mass low in the chassis. The 8.6 kWh Endurance pack provides 60–115 km race-pace range or up to seven hours, with a later 5.8 kWh Sprint pack planned to reduce weight. A mobile app adjusts throttle response and power delivery profiles for different riding styles. The EXR is planned for selected European markets starting Q4 2027 for both competitive and recreational use.

"Developed over three years by a team with roots in electric superbike racing, the motorcycle pairs a 70-horsepower drivetrain with a patent-pending battery-swapping system that lets riders replace depleted packs in less than 30 seconds without tools. Radian plans to launch the EXR in selected European markets from Q4 2027, offering the bike for both competitive and recreational riding."

"The removable pack slides through a natural rotational motion that allows riders to quickly swap batteries trackside while keeping the electric drivetrain's rotating mass centered low within the chassis. The production model arrives with an 8.6 kWh Endurance battery offering between 60 and 115 kilometers of race-pace range, or up to seven hours of riding depending on terrain and intensity. A lighter 5.8 kWh Sprint pack is planned for a later release, reducing the motorcycle's overall weight from 125 to 113 kilograms."

"The EXR uses Radian's curved InfiniPack battery system, designed to support ergonomic battery swapping and the overall structure of the motorcycle. Modular storage system removes the need for riding backpacks. The drivetrain combines a 336-volt electric motor, carbon-sleeved rotor, and proprietary inverter technology to deliver 1060 Nm of torque directly to the rear wheel from standstill."

"The system revs continuously up to 14,000 RPM, without using a conventional gearbox, allowing riders to navigate technical terrain without shifting gears. Through the accompanying mobile app, users can adjust throttle response and power delivery profiles depending on riding style, from low-end torque for hard enduro sections to smoother top-end performance for sand riding and high-speed tracks."
