The benchmark Stark Varg, road-registered: up to 80 hp in a ~198 lb package, with a range that keeps it a trail bike with plates rather than a true highway dual-sport. Decoded with real physics, true five-year cost, and sources on everything.
Essentially the race bike road-registered: a genuine 80 hp in a ~198 lb machine, with class-leading power-to-weight and near-zero maintenance. The catch is range. Plan for ~60 real miles mixed (closer to 40 on the highway), ~80 hp verified (configurable 60 or 80), ~$9,700 net to own over 5 years, and a "dual-sport" that is really a trail bike with plates.
Assumptions: recreational use ~100 hr/yr, $0.17/kWh, off-road gear budget higher, minimal registration, resale ~40% at year five, no battery replacement in five years. Stark cites ~$600 per 100 hr running cost versus ~$6,300 for an equivalent gas bike. Full table in §10.
Every module behind the headlines: who it is for, claims vs. physics, true cost, reliability, parts, and the standard scorecard. All sourced.
The benchmark electric motocrosser, road-registered. A configurable 60 or 80 hp in a ~198 lb chassis, a structural 7.2 kWh battery, and near-zero scheduled maintenance. Plan for ~60 real miles mixed (closer to 40 on the highway), ~$9,700 net to own over 5 years, and a phenomenal trail weapon that is technically a dual-sport but practically a trail bike with plates. Here is exactly how we get there.
Start here, the right answer depends entirely on who is asking.
Same bike, very different answer depending on the rider. We lead every report with this so nobody buys the wrong machine.
The sweet spot. Phenomenal handling, smooth power delivery in single-track, and class-leading power-to-weight with plates, so you can legally ride to the trailhead. For technical sessions under a few hours, this is the bike.
Where the EX delivers. A genuine ~79 bhp, configurable to 60 or 80 hp, well above a 450 motocrosser's ~60 bhp in a lighter package. The power-to-weight is real and the dyno backs the brochure.
The honest catch. "Dual-sport" is technically accurate and practically optimistic. With ~60 miles mixed and ~40 on the highway, fire-road days and highway slogs leave you range-anxious. It is not a distance tool.
A repeated owner gripe (echoed on the Electric Dirt Riders forum) is a stiff, uncomfortable seat over longer rides. It is built to race, not to lounge, and the tall 37 in seat suits taller riders.
Same bike, two stories. The struck-through line is what the listing tells you; the big number is what to actually expect. The "why" is in Part C.
What is genuinely clever, and which "innovations" are really table-stakes. The part the brand's own page never tells you.
The standout features, rated honestly. Each badge tells you whether it is a real engineering edge, normal for 2026, or marketing gloss.
The headline edge, and it is real. Up to ~79 bhp configurable in a ~198 lb chassis is class-leading power-to-weight, with plates attached. Essentially the benchmark race bike road-registered. Nothing else in the segment touches it on paper or in testing.
★ Genuine edgeA handlebar switch with five modes lets you dial power (60 or 80 hp), engine braking and the regen curve. Genuinely useful for matching the bike to terrain or rider, and to cap a newer rider.
✓ SolidAn annual gear-oil, coolant and brake-fluid service is about it; the motor and controller ask for nothing. Against a gas motocrosser's constant top-end work, this is a real ownership saving.
✓ SolidThe 7.2 kWh pack is a structural, load-bearing part of the chassis, which is clever packaging. It also means the battery is not removable, so charging is tied to the bike and there is no portable charger to carry.
✓ SolidMarketing specs vs. the physics. The math is simple, battery capacity and a few formulas, so let us run it.
The rare module where the marketing and the dyno agree. Up to 80 hp is not fluff: testers confirmed around 79 bhp, configurable between 60 and 80.
Convert the configurable outputs to the unit everyone feels:
The headline trap. Stark quotes range as hours of ride time, not miles, and the hours-of-use framing flatters it. Translate to distance and it is short. Here is the arithmetic.
Step 1, real energy in the tank. The EX uses a 7.2 kWh structural pack (slightly larger than the 6.5 kWh MX). The voltage and amp-hour split is not published, so we work from the kWh rather than inventing a V×Ah pair, then apply the usable-energy haircut.
Step 2, how much you spend per mile. A race motor in a light chassis drinks energy, and it climbs hard with speed because drag rises with the square of speed. Technical trail riding is efficient by distance; sustained road speed is brutal.
~104 mph claimed, and the power is genuinely there. But reaching for road speed is exactly what collapses the range above.
Held at sustained road speed, consumption spikes toward ~158 Wh/mi. Run the same range formula pinned:
So the speed and any kind of distance on the same spec sheet are mutually exclusive: you get the pace or the range, never both. On a bike Stark markets as a street-legal dual-sport, that is the most important thing the spec sheet never says out loud, and even Cycle News concluded the battery does not provide the range needed for highway, high-speed trail or fire-road use.
Charge time is just battery size ÷ charger power, and here the charger lives in the stand. It is quick, but the structural battery cannot come out.
Shopping for one of these, you will see the same bike listed with different numbers. They are not all lying, here is how to read them.
| You will see | What it really is | Trust it? |
|---|---|---|
| "up to 6 hours" | Ride time, not distance. Mixed real is ~60 mi; ~40 on the highway. | hours, not miles |
| 60 hp / 80 hp | Configurable via the handlebar switch. ~79 bhp confirmed at the 80 setting. | real |
| 7.2 kWh battery | Structural pack on the EX, slightly larger than the 6.5 kWh MX. Not removable. | real |
| "$12,900 / $13,900" | 60 hp standard vs the 80 hp Alpha package. Check which you are pricing. | check the variant |
| "Street legal" | Genuinely road-registered (lights, signals, foot brake), but range limits true road use. | legal, but short range |
| Varg MX vs Varg EX | The MX is the off-road-only racer; the EX is the road-registered version. | check the model |
The sticker is the smallest number in the story. Here is the whole bill.
The MSRP is a headline, not a checkout total. Here is what actually leaves your bank account on day one.
| Line item | Typical | Notes |
|---|---|---|
| Bike (MSRP) | $12,900 | 60 hp standard; 80 hp Alpha ~$13,900 |
| Delivery / freight | $200–$600 | Direct-sales from Stark Future |
| Sales tax (~8%) | ~$1,030 | Varies by state |
| Registration / plate | $50–$200 | Street-legal dual-sport |
| Off-road gear (helmet, boots, armor) | $500–$800 | Non-negotiable on an 80 hp dirt bike |
| Realistic out-the-door | ≈ $14,700–$15,500 | Before a single mile |
The number almost no one shows you. We itemize it, show the math, and state every assumption so you can adjust it to your own riding.
| Cost over 5 years | Estimate | What drives it |
|---|---|---|
| Purchase (MSRP) | $12,900 | 60 hp standard; tax/freight vary |
| Gear (one-time) | $800 | Helmet, boots, off-road armor |
| Maintenance (tires, fluids, consumables) | $600 | Annual gear-oil/coolant/brake service |
| Insurance + registration | $500 | Minimal; recreational use |
| Electricity (charging) | $120 | Almost nothing, math below |
| Battery (replace / upgrade) | $0 | None expected in 5 yr; 2yr/500-cycle warranty |
| 5-year total (before resale) | ≈ $14,920 | |
| Resale value (yr 5) | – $5,200 | ~40% of MSRP |
| Net true cost to own | ≈ $9,720 | ≈ $1,944 / year |
What breaks, who fixes it, and whether you can get parts.
We read the reviews and owner forums so you do not have to, and summarize the recurring themes, not cherry-picked raves.
A bike is only as ownable as its parts and service supply. Here the EX is fair: better supported than most e-MX startups, but not at gas-dealer levels.
Stark Future sells direct from Barcelona with a growing US presence. Service is centralized through the company, and the aftermarket is still emerging, better than most e-MX startups, but well short of the deep, decades-old catalogs around a KTM or Honda. OEM parts and consumables come through Stark; specialist support depends on your proximity to their service network. Budget for longer parts logistics than a mainstream dirt brand.
| Part category | Availability | Rough cost |
|---|---|---|
| Tires, brakes, fluids | good | $50–$300 |
| OEM service via Stark | centralized | through the brand |
| Battery / controller (OEM) | fair | dealer / warranty only |
| Aftermarket accessories | emerging | growing catalog |
One scorecard, identical axes on every bike.
Every e-moto on the site is scored on these same eight axes, by the same rules, so a 7 here means the same thing as a 7 anywhere.
Our standing methodology, run identically on every e-moto, including bikes we would otherwise have reason to flatter.
The only honest way to compare two batteries. When only the kWh is published, as here, we use that and say the V/Ah split is not stated rather than inventing it.
You never use 0 to 100%. The BMS holds a reserve and voltage tapers at the bottom. We assume ~88%.
Consumption is the lever: efficient on technical trail, brutal at road speed. Drag rises with speed².
Always ask which number a spec quotes. Here the ~80 hp is real and dyno-confirmed.
"Fast charging" is meaningless without the power. The stand charger refills the pack in under 2 hr on a 3.3 kW outlet.
| Cost assumption | We used | Change it if… |
|---|---|---|
| Annual use | ~100 hr/yr recreational | You ride more → tires & fluids rise |
| Electricity rate | $0.17 / kWh (US avg) | Your utility differs |
| Sales tax | ~8% | Your state differs |
| Battery life | No replacement in 5 yr | 2yr/500-cycle warranty; hard use → sooner |
| Resale | ~40% of MSRP at yr 5 | Condition & market vary |
