In the world of electric dirt bikes, two models are making waves in 2025: the Stark VARG EX and the Sur-Ron Ultra Bee. Both bikes offer impressive power, innovative features, and solid designs, but each caters to different types of riders. Let’s dive deep into their specifications, performance, and unique features to help you decide which one might be the best fit for your riding style.
Power and Performance
The Stark VAG EX and Sur-Ron Ultra Bee both deliver impressive power and performance. The VAG EX features a carbon-fibre sleeved motor with a peak power of 45 kW or 60 hp, upgradable to 60 kW or 80 hp and 1036 Nm of torque.
Its 14,200 rpm and 11 kW of continuous power ensures exceptional speed and handling over long distances, while the 7, 2 kWh integrated battery provides a solid balance between weight and capacity. Riders can expect nearly two hours of run time in expert mode. The Sur-Ron Ultra Bee, with a 12.5 kW motor and 440 Nm of torque, may not match the VAG EX in peak power, but still delivers an exciting ride.
Its 90 kmph top speed and customisable ride modes, including Eco, Daily and Sport, offer solid versatility. With more than 140 km of range at cruising speeds and 240 mm of suspension travel, the ULTRA B is well suited for longer adventures and challenging terrains.
Battery and Charging
The Stark VAG EX and Sur-Ron Ultra Bee both come with strong battery setups, but the VAG EX takes the lead in capacity.
With a 7.2 kWh battery, the VAG EX offers nearly two hours of run time in expert mode. The fully integrated battery weighs 32 kg, which adds to the bike's durability and power output. Charging is quick too, with a 3.3 kW charger that fully charges the bike in just about two hours.
The Sur-Ron Ultra Bee features a 4,070 Wh battery, which is slightly smaller in capacity but still provides excellent performance. Weighing 20.2 kg, its removable battery is a convenient option for charging, either on the bike or separately. The ULTRA BEE also offers fast charging, taking around four hours to fully recharge, though it's not as quick as the VAG EX.
A standout feature of the ULTRA B's battery is its long lifespan, able to endure more than 1,500 charge cycles while retaining over 80% of its capacity.
Chassis and Suspension
Both bikes are built to be tough, but each takes a slightly different approach to design. The Stark VAG EX features a sturdy, tubular chromoly steel frame paired with an aluminium rear subframe.
Its suspension, provided by KYABA, offers a solid 300 mm front travel and 50 mm in the rear, making it perfect for tough, off-road terrain. With a 345 m ground clearance and titanium rear sprocket, the VAG EX is engineered for extreme conditions while still delivering a smooth, controlled ride. The Sur-Ron Ultra Bee, on the other hand, opts for a lighter forged aluminium frame, reducing overall weight for better agility.
It has a 37 mm inverted front fork and 240 mm of rear travel, making it well equipped for rough trails. Its ground clearance of 318 mm is slightly higher than the VAG EX, allowing it to easily tackle obstacles on the trail. Weighing in at 85 kg for the MX model, 93 kg for the road version, the ULTRA BEE is noticeably lighter, making it more manoeuvrable, especially for riders who prioritise agility.
Brakes and Safety Features
When it comes to brakes, both bikes are equipped with high-quality systems designed for maximum stopping power. The Stark VAG EX features Brembo 2-piston calipers with a 206 mm front disc and independent front-dashaush rear braking systems. This setup ensures that the bike provides excellent control, even when descending steep trails or when you need to stop quickly on rough terrain.
The Sur-Ron Ultra Bee is equipped with bilateral 4-piston hydraulic 240 mm discs at both the front and rear, paired with EABS, offering exceptional stopping power. The regenerative braking system allows riders to recapture energy during braking, improving overall efficiency and range. This is an excellent feature for riders who want to maximise battery life during longer rides.
Technology and Features
The Stark VAG EX excels when it comes to tech features. Its full mapping navigation system, integrated with the Arkenstone smartphone app, offers advanced capabilities like ride tracking and route planning. With more than 100 riding modes and traction control, the VAG EX allows riders to fully customise their experience.
The PIN code or Face ID ignition system adds an extra layer of security, ensuring that only authorised riders can start the bike. The Sur-Ron Ultra Bee doesn't quite match the VAG EX in terms of high-tech features, but still delivers an impressive set of user-friendly tools. Its LCD multifunction display gives essential information like battery status, speed and trip details.
The STCS traction control system and Burr's regenerative braking help improve both performance and efficiency. Plus, with practical additions like a USB port, horn and road model lights, the Sur-Ron Ultra Bee provides extra convenience for everyday use.
Comfort and Practicality
The Stark VAG EX is larger, with a seat height of 966mm and a wheelbase of 4088mm disc, making it stable but less ideal for shorter riders.
Its weight, likely over 130kg, and 9kg motor add to its robust off-road capabilities. In contrast, the Sur-Ron Ultra Bee is lighter at 85kg for the MX version and 93kg for the road version. With a seat height of 9mm and a wheelbase of 1380mm, it's more compact and agile, making it easier to manoeuvre through tighter trails and obstacles.
Price and Warranty
In terms of warranty, the Stark VAG EX offers 24-month coverage for both the bike and its battery, providing solid peace of mind. The Sur-Ron Ultra Bee, while offering a shorter one-year warranty, still ensures solid protection for a year. As for price, the Stark VAG EX likely carries a heftier price tag due to its premium performance specs.
However, the Sur-Ron Ultra Bee offers fantastic value, especially with its impressive battery life, range and performance, making it a top contender for riders who want a high-performing bike without the steep price.
