Stark VARG EX Alpha 80HP – road‑legal electric enduro motorcycle
The Stark VARG EX Alpha 80HP is a street‑legal electric enduro and motocross motorcycle that combines an 80 hp adjustable powertrain with a high‑capacity 7.2 kWh battery, road equipment and advanced connectivity for off‑road and mixed on‑road use.
Key highlights
- 80 hp adjustable electric drivetrain: High‑performance 360 V permanent‑magnet AC motor with single‑speed transmission, offering power maps from low‑output trail modes up to a peak of around 80 hp to match various rider levels and surfaces.
- Upgraded 7.2 kWh battery: Gen‑2 battery pack with honeycomb magnesium housing, designed as a structural element in the chassis to lower the center of gravity and extend range compared with earlier versions.
- Road‑legal enduro configuration: Equipped with a powerful 4,000‑lumen LED headlight, integrated LED indicators and license‑plate holder, making the bike suitable for street sections between trails where regulations permit.
- High‑strength chassis: Steel main frame with a lightweight carbon‑fiber subframe, engineered for controlled flex, stability and precise feedback in technical enduro and trail riding.
- KYB long‑travel suspension: Closed‑cartridge KYB fork and linkage‑type KYB rear shock, both fully adjustable and tuned for enduro use with approximately 300 mm of wheel travel front and rear.
- Brembo braking system: Hydraulic disc brakes with a large front rotor and dedicated rear rotor for confident stopping power in steep and low‑grip terrain.
- Smartphone‑based control: Integrated Stark Arkenstone smart device provides a color display, GPS navigation, ride‑mode management and access to detailed power, regeneration and engine‑braking settings.
- Quiet, zero‑emission operation: Electric drive eliminates exhaust emissions and significantly reduces noise, while removing many conventional engine wear components.

Advanced control and connectivity
The Stark Arkenstone smart device integrated into the VARG EX Alpha 80HP acts as the bike’s display and control center, enabling configuration of power delivery, engine braking, regenerative settings and ride modes directly on the unit also provides GPS‑based navigation and ride logging, allowing detailed analysis of riding sessions and quick adaptation of the bike’s behavior to different riders, terrains and events.
Typical use cases
- Enduro and hard enduro riding: Long‑travel suspension, strong yet flexible chassis and instant electric torque make the bike suitable for demanding single‑track, rocky climbs and technical sections.
- Closed‑course motocross and practice tracks: Adjustable power delivery and quiet operation support use on practice facilities and tracks where conventional engine noise can be restrictive.
- Trail and exploration riding: Extended battery capacity, integrated lighting and navigation features support mixed‑terrain trips that combine forest trails, gravel and connecting road sections where regulations allow.
- Urban and mixed commuting: Road‑legal equipment and zero local emissions enable use in urban environments and daily riding, while still retaining full off‑road capability for weekend routes.
