Reviewed 13 October 2026. By MotoEbikes. Manufacturer specifications are identified below; this is buying and ownership guidance, not an independent road test.
There is no single range figure that describes every Stark VARG. A supermoto commute is best assessed in miles; motocross and enduro often need riding time as well. The current MX 1.2, EX and SM have manufacturer-specified 7.2kWh batteries, but their intended use and energy demand differ.
What Stark’s published figures actually tell you
| Model or activity | Published evidence | How to use it |
|---|---|---|
| SM highway | 49 miles in Stark’s filmed testing | A manufacturer test result, not a guaranteed UK motorway range. |
| SM mixed urban | 73 miles in Stark’s filmed testing | A different duty cycle from sustained faster-road riding. |
| EX enduro and motocross | Separate riding-time examples by discipline and rider level | The EX page says its proof videos used the earlier 6.5kWh battery. Do not label those clips as MotoEbikes tests of the 7.2kWh bike. |
| MX 1.2 motocross | Riding time depends on track and pace | Use records from comparable sessions; road miles are a poor substitute. |

Why two riders get different results
- Speed and wind: a sustained fast road section can change the trip more than its mileage suggests.
- Terrain: soft ground, climbs, mud and repeated acceleration change the work the motorcycle must do.
- Rider and load: record rider weight with kit and any carried equipment.
- Temperature and battery condition: compare similar conditions and account for an older pack’s condition.
- Tyres and configuration: record tyres, pressures, gearing where applicable and power or regeneration settings.
- Stops: elapsed time on a day out is different from moving time under power.
A transparent planning example
The following is an illustration, not a measured VARG result. Suppose a rider budgets 5.76kWh for a journey. That is 80% of a nominal 7.2kWh pack, before establishing the bike’s actual usable energy. At an assumed consumption of 0.12kWh per mile, the arithmetic gives 48 miles; at 0.18kWh per mile it gives 32 miles.
Planned distance = energy budget ÷ consumption per mile. Neither assumed consumption figure is a Stark test measurement. The example shows why the same battery can support very different planning distances. A nominal pack rating and dashboard percentage are not a calibrated measurement of usable energy.
Build a useful estimate for your route
Start with a short, repeatable route that finishes with ample charge. Record distance, moving time and starting and finishing charge, together with conditions and configuration. Repeat it before extending the journey. For a commute, include the return trip, normal load, faster sections and an alternative route.
As an initial comparison only, if a 15-mile ride uses 30 percentage points, it used two percentage points per mile on that outing. Do not extend that into a promise of 50 miles from full to empty: the display is not perfectly linear, conditions can change, and you still need a reserve. The useful question is whether several representative rides leave comfortable margin for your intended journey.
For EX and MX, record sessions rather than just a day
A three-hour visit to a track might contain much less than three hours of riding. Log each session’s moving time, terrain, pace and charge change. Describe the discipline precisely: flowing enduro, slow technical terrain and deep motocross sand are not interchangeable.
Also record any charging during breaks. A day completed with a lunchtime top-up is not evidence that the entire day was ridden on one charge. Compare sessions at similar pace before drawing conclusions about a setting or component.
Can lower power or more regeneration guarantee more range?
A lower power ceiling can help a rider avoid some energy-intensive acceleration, but the setting alone does not determine consumption. Regeneration settings change deceleration behaviour; they are not a fixed percentage range bonus. Select controllable settings appropriate to the bike and conditions, following its manual, then measure your actual use.
Do not reduce range planning to a claim that “60HP lasts longer than 80HP”. The riders, routes, settings and demanded power need to be comparable first.
Range, battery life and charging are different questions
Range is the distance or riding time between charges. Battery service life concerns retained capacity and condition over time. Charging time concerns the energy being added and the equipment supplying it. None can be reliably answered using another one’s headline number.
For charging arrangements and a worked electricity-cost example, use the Stark charging guide. For buying choices, compare SM, EX and MX 1.2.
