The short answer
The fastest electric dirt bike we track is the Sur-Ron Storm Bee at about 75 mph (VoltRipper Score 89). Behind it, the Stark Varg runs roughly 68 mph, the Rawrr Mantis X Pro hits ~65 mph, and the Onyx RCR / E-Ride Pro SS / Arctic Leopard XF Pro cluster around 60 mph. The current Sur-Ron Ultra Bee HP is still extremely quick, but its verified top-speed figure is about 59 mph, not the older 68 mph claim.
One surprise worth calling out: in stock motocross gearing, the Storm Bee beats the Stark Varg on top speed despite the Stark's enormous 60 kW motor — because top speed is set by gearing and tuning, not raw watts. The Stark is highly configurable, though: geared for speed it can run well past 80 mph (owners have reported triple digits), at the cost of the race-ready acceleration it's built for. So "fastest" is partly a tuning choice, not a fixed spec — and fastest ≠ most powerful.
An honest note on "fastest"
Chasing top speed is fun, but be clear-eyed about the trade-offs before you buy the quickest bike you can find:
- These are expert machines. The fastest bikes are also the heaviest and most demanding — the wrong first bike.
- Mostly not street-legal. Assume off-road use only; road riding needs a kit and a permitting state.
- Speed is the least useful number for most riding. On real trails, handling, torque, and range matter far more than a top-speed figure you'll rarely reach.
Buy fast because you genuinely want the capability — not because a bigger number must mean a better bike.

Outright fastest — Sur-Ron Storm Bee. A full-size, motorcycle-class machine and the top speed on our board, backed by the deepest support network in the segment. (Full review →)
Fastest under $5k — Rawrr Mantis X Pro. ~65 mph and 15 kW for about $4,499 — roughly half the price of the flagships it shadows. The Arctic Leopard XF Pro is cheaper at about $3,699 and still reaches the 60 mph tier, but the Rawrr is the quicker sub-$5k pick if outright pace is the goal. (Full review →)
Fastest with the most bike — Stark Varg. The Varg's 60 kW makes it the acceleration king even if its top speed is capped below the Storm Bee's; it's a purpose-built electric motocross weapon at a halo price.
The real-world caveats
Every bike here ships factory-tuned, and several are speed-limited out of the box — the quoted top speeds often require derestriction, which is on you and can affect warranty and legality. And remember the range reality: the faster you ride, the harder the battery drains, so these top-speed numbers and real-world range live at opposite ends of the throttle.
The bottom line
For outright speed, the Sur-Ron Storm Bee wins; for the quickest sub-$5k buy, the Rawrr Mantis X Pro is the standout; and for sheer power, the Stark Varg. But if you're a newer rider — or you mostly ride trails — the fastest bike isn't the best bike for you. Run the Find Your Ride configurator to match speed to your actual skill and riding.

FAQ
What is the fastest electric dirt bike?
On our board, the Sur-Ron Storm Bee is the fastest at about 75 mph — notably quicker than even the far more powerful Stark Varg (68 mph), because top speed comes down to gearing and tuning, not just watts. The Rawrr Mantis X Pro hits ~65, several bikes cluster near 60, and the current Ultra Bee HP sits just below that at about 59.
Is a faster electric dirt bike better?
Not for most riding. The fastest bikes are the heaviest, most expensive, and most expert-oriented, and they're generally not street-legal. For real trail and dirt riding, handling, torque, and range matter far more than top speed. Buy fast because you want the capability, not because more speed automatically means a better bike.
What's the fastest electric dirt bike for the money?
The Rawrr Mantis X Pro is the quickest sub-$5k pick we track — about 65 mph and 15 kW for ~$4,499. If you can live with the smaller 17/14 chassis, the Arctic Leopard XF Pro is the cheaper 60 mph value play at about $3,699.
Are these fast electric dirt bikes street-legal?
Generally no. The fastest models ship as off-road machines; a few can be converted with a kit where state law allows, but you should assume off-road use only and check our street-legal guide and your state's rules before planning any road riding.
