Stark VARG SM Alpha 80HP – Electric Supermoto Benchmark
The Stark VARG SM Alpha 80HP is a street-legal, all-electric supermoto developed specifically for asphalt a claimed 80 horsepower from a compact 360 V PMAC motor, race-derived chassis geometry and premium suspension and braking components, this model delivers explosive acceleration and ultra-precise handling in urban environments, kart tracks and tight mountain roads.
Main Highlights
- Alpha specification with peak 80 hp output and instant electric torque for aggressive supermoto performance.
- 7.2 kWh battery pack engineered for high power delivery and repeated hard acceleration.
- Claimed weight around 124.5 kg (274.5 lb) for a class-leading power-to-weight ratio.
- Street-homologated chassis, lighting and equipment for road use in multiple regions.
- Supermoto-specific geometry for fast direction changes, stability on asphalt and confidence under hard braking.
- Android-based Arkenstone-style cockpit with integrated display and advanced ride electronics.
Chassis, Suspension and Brakes
The Stark VARG SM Alpha 80HP is built around a tubular steel frame designed to keep mass centralized and low. A forged subframe and machined triple clamps contribute to chassis stiffness and steering precision while keeping overall weight -optimised geometry allows the bike to hold tight lines, flick rapidly from side to side and remain stable under heavy braking.
- Fully adjustable KYB 48 mm front fork with supermoto-specific settings and approximately 290 mm (11.4 in) of travel.
- KYB rear shock, adjustable for preload, compression and rebound damping, with generous travel for kerbs, potholes and track use.
- CNC-machined triple clamp with integrated handlebar mounts, tuned for the ideal balance of flex and rigidity.
- Radially mounted Brembo Stylema four-piston front caliper with 320 mm front disc for powerful, fade-resistant stopping.
- Brembo rear brake with 220 mm disc, available with either traditional foot brake or optional rear handbrake configuration.
- 17-inch supermoto wheelset with tubeless-capable rims and performance road tyres in 120/70-17 front and 140/70-17 rear sizes.
Electric Powertrain and Battery Technology
The heart of the Stark VARG SM Alpha 80HP is a high-voltage 360 V permanent magnet AC electric motor paired with a single-speed motor is tuned to deliver the immediate response and controllable torque that supermoto riding demands, from technical kart circuits to slow-speed urban sections.
- 360 V PMAC motor with Alpha mapping for up to 80 hp peak power.
- Substantial rear-wheel torque for rapid launches, strong midrange drive and effortless wheelies.
- 7.2 kWh battery pack in a compact, robust housing for efficient cooling and durability.
- Real-world claimed range of around 81 km (approximately 50 miles), depending on riding style and conditions.
- Approximate charge time of about 2 hours with a suitable Level 2 charger.
- Portable 3.3 kW charger designed to be compact enough to carry, enabling convenient recharging between sessions or during stops.
Ergonomics and Rider Interface
The riding position of the Stark VARG SM Alpha 80HP is tuned for aggressive supermoto techniques yet remains versatile enough for everyday road use. A relatively tall seat height and narrow midsection give ample leverage over the bike, while wide handlebars and carefully selected offset promote precise control at high lean angles and during stoppies or wheelies.
- Seat height of about 36.8 in, offering commanding visibility and leverage.
- Wide supermoto-style handlebar with integrated clamps for direct steering response.
- Multiple seat options (Standard, Grip, Super Grip) to match preference and riding style.
- Choice of rear brake layout: traditional foot brake or bar-mounted handbrake for advanced control.
- LED lighting with a powerful headlamp and integrated indicators for road legality and visibility.
Electronics and Ride Customisation
The advanced electronic suite transforms the Stark VARG SM Alpha 80HP into a highly configurable Android-based display acts as the central hub for ride modes, power delivery, regenerative braking and other parameters, allowing detailed customisation for different surfaces and rider preferences.
- Integrated Android-style display providing key ride data, navigation capability and access to setup menus.
- Multiple power maps ranging from manageable urban settings to full Alpha 80 hp output.
- Adjustable regenerative braking to simulate engine braking or maximise coasting efficiency.
- Over-the-air capable electronics architecture for future feature and software enhancements.
Typical Use Cases
- Urban and city riding where instant torque, compact dimensions and strong brakes are essential.
- Kart tracks and short circuits demanding rapid transitions, hard braking and strong corner exit drive.
- Tight, technical backroads where a lightweight supermoto-style chassis outperforms larger, heavier machines.
- Skill development sessions focused on wheelies, stoppies and advanced bike control techniques.
- Short-distance commuting with an emphasis on performance, low noise and minimal mechanical maintenance.
