The landscape of high-performance electric motorcycles has fundamentally shifted. Buyers are no longer limited to a single closed-course track machine. The expanding Stark VARG lineup includes three highly specialized platforms: the MX (Motocross), the EX (Enduro/Dual-Sport), and the newly released, fully road-legal SM (Supermoto).
At RonsterBikes, we put these high-voltage machines through rigorous testing on local tracks, fire roads, and canyon twisties. Choosing the right model comes down to your primary riding environment, wheel geometry, and street-legality needs.

1. Stark VARG MX: The Pure Motocross Weapon
The Stark VARG MX is the uncompromised machine that started the electric dirt revolution. Stripped of all legal road hardware—meaning no heavy headlights, turn signals, or license-plate brackets—the MX model is engineered strictly to dominate closed circuits and motocross tracks.
It utilizes a classic motocross 21-inch front and 19-inch rear wheel combination designed to slice through prepped dirt ruts and limit tire sidewall flex during heavy cornering forces. The KYB suspension package features 310mm of travel, valved firmly out of the box to survive massive freestyle jump casings and deep stadium-style whoops. If your focus is purely on track gate drops, cutting lap times, and riding closed MX facilities, this is your definitive platform.
2. Stark VARG EX: The Go-Anywhere Dual-Sport Hybrid
The Stark VARG EX transitions the platform into a highly versatile enduro and dual-sport weapon. It retains the rugged character of an off-road bike but arrives with factory lighting, a forest-ready skid plate, handguards, and a Manufacturer’s Statement of Origin (MSO) to facilitate street registration at your local DMV.
Mechanically, the EX steps down to an 18-inch rear-wheel configuration. Shifting to an 18-inch wheel allows you to mount tires with a significantly taller sidewall profile, maximizing impact absorption over square-edge rocks, logs, and roots.
The KYB suspension is valved noticeably softer through its 300mm of travel, keeping the tires firmly planted for extreme traction on technical single-track climbs. The EX comes standard with the 7.2 kWh high-capacity battery pack, stretching your ride time up to several hours deep in the backcountry.
3. Stark VARG SM: The Ultimate Electric Supermoto Machine
The Stark VARG SM represents a massive engineering leap toward asphalt dominance, transforming the off-road frame into a street-legal carving tool.
The SM swaps out the dirt wheels for lightweight 17-inch wire-spoke wheels wrapped in tubeless street tires. To handle high-grip asphalt pavement braking forces, the front stopping components are heavily upgraded to a massive 320mm floating rotor clamped by a radially mounted Brembo 4-piston monoblock caliper.
The chassis geometry is radically tightened for street carving. It features an aggressive 16mm triple-clamp offset and street-tuned, ultra-stiff KYB suspension with 290mm of travel to prevent chassis dive under hard cornering. Paired with a tall-ratio 15/47 street-gearing setup, the 80 hp Alpha motor propels the 124 kg SM down paved canyon roads and urban supermoto tracks with relentless speed.
The Verdict: Which Stark Variant Belongs in Your Garage?
•Buy the Stark VARG MX if: You are a dedicated motocross racer, veteran rider, or track purist who rides exclusively on closed courses and has zero desire for headlights, license plates, or public single-track exploration.
•Buy the Stark VARG EX if: You are an off-road adventurer, trail rider, or dual-sport enthusiast. If your primary playground consists of technical woods, mountains, and muddy single-track, but you still need road legality to link trail segments together cleanly, the EX is the ultimate versatile hybrid.
•Buy the Stark VARG SM if: You want a dedicated tarmac weapon. If you live for canyon carving, asphalt track days, and high-speed urban commuting, the factory-tuned SM out-handles and out-accelerates traditional gas supermotos.
