Starkvarg and premium e-motocross compared: Stark Varg, KTM Freeride E and Zero FX
By Kobolt Bikes · ·

Starkvarg, as many riders type it, is the Stark Varg from Stark Future, and in our catalogue it costs €11,868 against €10,395 for the KTM Freeride E-XC and €10,115 for the Zero FX. The Stark Varg is the clear power leader at 60 kW peak, but the right premium electric dirt bike depends on whether you want raw power, long range or a lighter, simpler bike, not on the largest number. This guide compares the five premium models we stock with euro prices, published specifications and the one calculation most guides skip: what you pay per peak kilowatt and per kilowatt-hour.

Quick picks: Starkvarg, KTM and Zero side by side
Start with the table. Prices are our current catalogue prices in euro including delivery to Denmark. Power is the peak figure as published, battery is capacity, weight is the published weight and speed is the top speed in the specification we could source. A dash means we found no reliable figure and left it out instead of guessing. Click a model to open its product page.
| Model | Price | Motor (kW, as published) | Battery | Weight | Top speed |
|---|---|---|---|---|---|
| Stark Varg | €11,868 | 60 (80 hp) | 6 kWh | 110 kg | – |
| Stark Varg EX | €12,420 | 60–80 hp | 7.2 kWh | 120 kg | – |
| KTM Freeride E-XC | €10,395 | 18 (9 rated) | 3.9 kWh | 111 kg | 80 km/h |
| KTM Freeride E-SM | €10,579 | – | – | – | – |
| Zero FX | €10,115 | 33 (15 continuous) | 7.2 kWh | 131 kg | 137 km/h |
Three things stand out. First, the Stark Varg has 60 kW peak (80 hp) at 110 kg, the best power-to-weight in the group. Second, the Zero FX is the cheapest at €10,115 and lists the longest range, up to 164 km. Third, the KTM Freeride E-XC is the lowest powered at 18 kW peak, yet costs the most per kilowatt.
Starkvarg: the Stark Varg and the Varg EX
The Stark Varg costs €11,868 and lists a 60 kW peak motor (80 hp), a 6 kWh battery, a weight of 110 kg and full suspension with 310 mm of travel. Our product page describes it as a high-performance electric dirt bike for riders who want instant torque, quiet running and minimal maintenance. It is the bike for a rider who already has motocross skills and wants the most power available.
The Stark Varg EX at €12,420 is Stark's enduro variant: up to 80 hp (Alpha) or 60 hp (Standard), a 7.2 kWh magnesium battery that is also part of the structure, KYB suspension, Brembo brakes and a weight of about 120 kg. It costs €552 more than the Varg for about 20 percent more battery and 10 kg more weight, and it is the one Stark sells as road-legal in parts of Europe. We cover that below.

KTM Freeride E-XC and E-SM: the lighter, simpler pair
The KTM Freeride E-XC costs €10,395 and lists an 18 kW peak motor (9 kW rated), 42 N·m of torque, a 3.9 kWh battery, a top speed of 80 km/h and a weight of 111 kg. It is a premium bike with a real brand behind it, but it is the lowest powered here: the Stark Varg has about 3.3 times the peak power for €1,473 more.
The KTM Freeride E-SM at €10,579 is the supermoto version. We do not list power, battery or weight for it because we could not source reliable figures, so you will see dashes. Our product page says road legality depends on the market version and that we confirm the EU-compliant configuration before shipping, so ask us first.
Zero FX: the long-range dual-sport
The Zero FX costs €10,115 and lists a 33 kW peak motor (15 kW continuous), 106 N·m of torque, a 7.2 kWh battery, a range of up to 164 km, a top speed of 137 km/h and a weight of 131 kg. It is the heaviest bike here and the fastest, and with the longest range it suits riders who want to cover distance rather than race a track.
As with the KTM supermoto, our product page says road legality depends on the market version and that we confirm the EU-compliant configuration, usually a 250 W motor with a 25 km/h assist limit, before shipping. That is a very different bike from the one in the specification, so confirm exactly what you are buying.
Price per peak kilowatt and per kilowatt-hour
Divide each catalogue price by the published peak power and the Stark Varg comes out at about €198 per kW (€11,868 for 60 kW), the Varg EX at about €208 per kW at its 80 hp figure, the Zero FX at about €307 (€10,115 for 33 kW) and the KTM Freeride E-XC at about €578 (€10,395 for 18 kW). Per kilowatt-hour of battery, the Zero FX is the best at about €1,405 per kWh, followed by the Varg EX at about €1,725, the Stark Varg at about €1,978 and the KTM at about €2,665.
Read it carefully. Peak power is not rated power, and a higher figure only helps if you can use it. The Stark Varg is the value leader per kW and the Zero FX per kWh. The KTM is the most expensive on both measures, so choose it for the brand and the handling, not for the numbers.
Battery, range and weight: what to expect
Bigger batteries mean longer days, but also more weight. The Zero FX carries 7.2 kWh and weighs 131 kg, the Varg EX carries 7.2 kWh at about 120 kg, the Stark Varg carries 6 kWh at 110 kg and the KTM Freeride E-XC carries 3.9 kWh at 111 kg. By simple division, the Varg EX has the most battery per kilogram at about 60 Wh/kg, ahead of the Zero FX and the Stark Varg at about 55 Wh/kg each and the KTM at about 35 Wh/kg.
The only range figure we list is the Zero FX claim of up to 164 km. Treat it as a best case: real range falls with speed, rider weight, terrain and temperature, and a bike ridden hard on a track will use its battery far faster than one cruising on a trail.
Stark Varg street legal? What the rules say
If you are asking whether a Stark Varg is street legal, the answer depends on the model. Our Stark Varg is sold as an off-road bike for private land. The Varg EX is different: our product page says Stark sells it as its road-legal enduro (A1 licence class in Europe), but in Denmark it still has to be registered and homologated before you ride it on the road. Under Regulation (EU) No 168/2013, a two-wheeler registered for public roads must be type-approved in an L category such as L1e or L3e, and an off-road-only model does not have that approval.
Rules differ by country, so check the national guide before you buy: Denmark, Sweden, Germany, Spain and Finland. For the wider picture of electric dirt bike rules, see our electric dirt bike buying guide.

Buying checklist and common mistakes
- Decide power or range first. The Stark Varg and the Zero FX are built for different things.
- Treat peak power as peak. Rated or continuous power is lower.
- Check road status per model. Only the Varg EX is sold as road-legal in parts of Europe, and it still needs registration.
- Match weight to the rider. The Zero FX is 131 kg; try lifting a bike before you buy.
- Beware of too-good prices. Buy from a seller with a registered business and a guarantee.
- Check parts and service. Brake pads, chains and tyres wear.
- Budget for protective gear. A helmet and protection are not optional.
