Stark VARG EX Enduro: 80HP Dyno Teardown, Arenacross Championship & Gas 450 Comparison
When Jack Brunell captured the UK Arenacross Championship aboard a Stark VARG against a full gate of factory 450cc four-stroke machines, motorsport history was made. The Stark VARG EX brings that championship-winning architecture to the enduro trails with full street homologation. Compare it with lightweight e-motos in our Surron Hyper Bee vs Light Bee X comparison and explore adventure tourers in our CFMOTO 450MT review.
1. 80HP Carbon-Sleeve Motor & 938 Nm Wheel Torque
The Stark VARG's motor weighs only 9 kg and utilizes a carbon fiber sleeve over the rotor to withstand centrifugal forces at 14,200 RPM. Producing 80 horsepower in the Alpha trim and an extraordinary 938 Nm of torque at the rear wheel, it accelerates with immediate traction that eliminates the front-wheel hop and clutch slippage inherent in gas motocross bikes.
2. Magnesium Honeycomb Battery & Waterproof IP69K Casing
The 7.2 kWh battery pack is housed within a flying-V patent-pending magnesium honeycomb casing that acts as the primary structural member of the chassis. Rated at IP69K, the bike can be fully submerged in river crossings or washed with industrial pressure washers without risk of moisture ingress. Fast charging on 240V AC power replenishes the pack from empty in under 2 hours.
3. The FIM Homologation Battle & Gas 450 Rivalry
Following Stark's Arenacross dominance, sanctioning bodies like the FIM initially restricted electric motorcycles from direct competition with 450cc four-strokes in MXGP, announcing a dedicated support class. On the track, the Stark VARG provides linear traction on hard-pack clay that gas bikes cannot match, while requiring zero oil changes or piston rebuilds.
