Zero's faired electric sport bike, the same 111 hp powertrain as the SR/F wrapped in bodywork, decoded with real physics: where the range actually goes when you leave town, what charging really takes, the true five-year cost of a $20,995 sticker, and who it is for. Sources on everything.
A genuinely fast, refined, US-built electric sport bike with an honest top end and a city-only range number. Plan for ~100 to 120 real miles mixed (not 187, and far less at 70 mph), 111 hp peak with supercar acceleration, about $14,665 net to own over 5 years, and yes, it is fully street-legal.
Assumptions: street-legal use, ~4,000 mi/yr, $0.17/kWh, belt-and-brake service only, full insurance and registration, resale ~45% of sticker at year five. 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 SR/F with a fairing. Same 17.3 kWh battery, same ~111 hp Z-Force powertrain, same 140 lb-ft of instant torque, built by Zero in Scotts Valley, California. Plan for ~100 to 120 real miles mixed (the 187 is a city number), ~$14,665 net to own over 5 years, and yes, it is fully street-legal. The bike is excellent; the use case has to match it. 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. Supercar 0 to 60 (~3.3 s), 124 mph, refined and comfortable for a sport platform, and a city-plus-canyon range that easily covers a spirited day built around a home charge.
Where the SR/S earns the premium. No clutch, no gears, belt-and-brake-only servicing, OTA software updates, and street-legal out of the box. A genuinely low-maintenance fast bike.
The mismatch. At a sustained 70 mph the range roughly halves, and even rapid charging takes well over an hour. Long stints between chargers are exactly what this bike is worst at.
A $20,995 sticker is a lot of money against the real-world motorway range. Brilliant machine, but the premium is hard to justify on cost-per-mile alone.
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.
What the SR/S adds over the naked SR/F, rated honestly. Each badge tells you whether it is a real edge, normal for the price, or marketing gloss.
The defining difference from the SR/F. Zero credits it with about a 13% range gain, genuine but conditional: it mostly shows up tucked at speed, plus real wind and weather protection.
✓ SolidZero's connected software platform, shared across the range. Features and tuning can evolve after purchase. A real convenience, but increasingly normal on premium EVs.
✓ SolidThe proven interior-permanent-magnet motor delivers ~111 hp peak and 140 lb-ft instantly, with strong roll-on even at highway speed. Refined, quick, and well-understood.
★ Genuine edgeA clean belt final drive and a single-speed transmission mean almost nothing to service. The quiet daily-ownership win behind the belt-and-brake-only maintenance bill.
≈ Now standard (for Zero)Marketing specs vs. the physics. The math is simple, battery capacity and a few formulas, so let us run it.
Here Zero is largely honest. The headline torque and the peak horsepower are both real; the only nuance is that an electric motor cannot hold peak power forever.
The Z-Force 75-10 motor makes a peak of about 111 hp at 5,600 rpm and 140 lb-ft of torque from a standstill. Convert the peak to watts and back to confirm the unit everyone feels:
The headline gap. The claim is not a lie, Zero explicitly calls it a city figure. It is a best-case low-speed number you will not see on the highway. Here is the arithmetic.
Step 1, real energy in the tank. The SR/S carries a 17.3 kWh pack on a roughly 116 V nominal architecture. We use the published energy directly:
Step 2, how much you spend per mile. Consumption (Wh/mi) is the whole game, and it explodes with speed because drag rises with the square of speed. Stop-start city riding sips ~85 Wh/mi; a steady 70 mph on a faired bike can hit ~155+.
Zero credits the fairing with about a 13% range gain over the naked SR/F. Genuine, but conditional, and it does not rescue the highway number.
Reviewers note the aero benefit mostly materializes when you are fully tucked at speed, the position the fairing was shaped for. Sit up in traffic and the advantage shrinks. It is a modest, real comfort-and-efficiency upgrade over the SR/F, not a transformation, and it does not change the basic fact that holding 70 mph still roughly halves the city range.
Charge time is just battery size ÷ charger power, and the SR/S has no DC fast charging, so the onboard and accessory chargers set the daily reality.
Shopping for one of these, you will see the same bike quoted with different numbers. They are not all lying, here is how to read them.
| You will see | What it really is | Trust it? |
|---|---|---|
| 17.3 kWh | The pack capacity, on a ~116 V nominal architecture. The number that sets real range. | real |
| 111 hp | Peak motor output at 5,600 rpm. Brief, but a genuine peak. | real (peak) |
| "187 miles" | City range only. Zero says so; highway is roughly half. | city-only |
| Power Tank / extra range | An optional accessory pack raises capacity and price. Check whether a quote includes it. | option |
| Rapid charge times | Require the 6.6 kW charger and a Level 2 station; the base charger is slower. | depends on hardware |
| SR/S vs SR/F | Same powertrain; the SR/S adds the fairing. Match the model to the spec. | check 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) | $20,995 | 2025 SR/S, base configuration |
| Destination / setup | $300–$600 | Dealer freight and prep |
| Sales tax (~8%) | ~$1,680 | Varies by state |
| Registration / first-year insurance | $400–$900 | Full motorcycle coverage |
| Starter gear (helmet, jacket, gloves) | $500–$1,200 | Non-negotiable at 124 mph |
| Realistic out-the-door | ≈ $24,000–$25,500 | 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) | $20,995 | Excl. gear; tax/freight vary by state |
| Insurance / registration | $1,500 | Full street-legal coverage |
| Maintenance (belt, brakes, tires) | $750 | Belt-and-brake-only servicing |
| Gear (one-time) | $500 | Helmet, jacket, gloves |
| Electricity (charging) | $320 | Cheap, math below |
| Battery (replace / upgrade) | $0 | None expected in 5 yr |
| 5-year total (before resale) | ≈ $24,065 | |
| Resale value (yr 5) | − $9,400 | ~45% of MSRP |
| Net true cost to own | ≈ $14,665 | ≈ $2,933 / year |
What breaks, who fixes it, and whether you can get parts.
We read the reviews and owner groups so you do not have to, and summarize the recurring themes, not cherry-picked raves.
A bike is only as ownable as its parts supply and dealer network. Here the SR/S is fair: real factory support, but a limited footprint.
The SR/S uses the same Zero dealer network and OTA support as the rest of the range, and it shares most parts with the SR/F, which helps availability. The aftermarket and the dealer footprint remain limited versus major combustion OEMs, so plan to lean on Zero dealers and the brand's own support for anything beyond consumables.
| Part category | Availability | Rough cost |
|---|---|---|
| OEM service parts (shared with SR/F) | fair to good | via Zero dealers |
| Tires, brakes, belt | good | $100–$400 |
| Accessories (luggage, screens) | fair | $80–$600 |
| Battery / powertrain | dealer only | via Zero service |
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 kWh is published, as here (17.3 kWh), we use it directly.
You never use 0 to 100%. The BMS holds a reserve and voltage tapers at the bottom. We assume ~90% on a large modern pack.
Consumption is the lever: ~85 Wh/mi city, ~134 mixed, 155+ at a steady 70 mph. Drag rises with speed².
Always ask which number a spec quotes. Peak sells bikes; continuous moves them.
"Fast charging" is meaningless without the charger's wattage. The ×1.1 covers losses and taper.
| Cost assumption | We used | Change it if… |
|---|---|---|
| Annual mileage | 4,000 mi/yr (20,000 / 5 yr) | You ride more → tires & charging rise |
| Electricity rate | $0.17 / kWh (US avg) | Your utility differs |
| Sales tax | ~8% | Your state differs |
| Battery life | No replacement in 5 yr | Very hard use → sooner |
| Resale | ~45% of MSRP at yr 5 | Condition & market vary |
