🏁 X-PRO STORM 150 DIRT BIKE
6.8 kW • 11 N·m • 65+ MPH • 4-SPEED MANUAL • 19"/16" BIG WHEELS
The X-PRO Storm 150 is a full-size gasoline dirt bike built around a 145cc single-cylinder, 4-stroke oil-cooled engine. It produces 6.8 kW at 7,500 ±500 RPM and 11 N·m at 5,500 ±500 RPM, paired with a 4-speed manual transmission, electric + kick start, and large 19"/16" tires.
With a perimeter-cradle steel frame, inverted hydraulic front forks, hydraulic disc brakes, 12.6" ground clearance and 35" seat height, the Storm 150 is designed for experienced teen and adult riders looking for a substantial off-road motorcycle with full-size proportions. (XProUSA)
🔥 145cc OIL-COOLED PERFORMANCE
6.8 kW ENGINE OUTPUT
The Storm 150 uses a Zongshen 145cc 4-stroke, single-cylinder engine with forced oil cooling.
Engine specifications
-
⚡ Displacement: 145cc
-
🔥 Engine: 4-stroke
-
1️⃣ Cylinder: Single
-
❄️ Cooling: Oil cooled
-
⚡ Maximum power: 6.8 kW / 7,500 ±500 RPM
-
💪 Maximum torque: 11 N·m / 5,500 ±500 RPM
-
📐 Bore × stroke: Φ56.5 × 57.8 mm
-
🔧 Compression ratio: 9.0:1
-
⛽ Carburetor: PZ27
-
🔥 Ignition: CDI
The oil-cooled design is intended to help manage engine temperatures during extended riding compared with a conventional air-cooled configuration. (XProUSA)
⚙️ 4-SPEED MANUAL TRANSMISSION
FULL CONTROL OVER EVERY GEAR
The Storm 150 uses a:
4-SPEED MANUAL TRANSMISSION
This gives the rider direct control over gear selection and engine RPM.
Power is transferred through:
#428 CHAIN • 14T/41T SPROCKETS
The combination of 6.8 kW, 11 N·m and 4-speed gearing provides a traditional motorcycle-style riding experience rather than an automatic drivetrain.
🚀 65+ MPH ADVERTISED TOP SPEED
The manufacturer lists:
65+ MPH
Actual maximum speed depends on rider weight and road conditions. (XProUSA)
Because the Storm 150 is capable of speeds above 65 MPH, it should only be operated by appropriately experienced riders in suitable off-road environments with proper protective equipment.
🔑 ELECTRIC + KICK START
The Storm 150 gives you two starting options:
⚡ ELECTRIC START
Convenient primary starting system.
🦶 KICK START
A mechanical backup starting system.
The electrical system uses:
12V / 4Ah STARTER BATTERY
This is a starter battery—not an electric propulsion battery.
There is no EV battery range or electric charging time because the Storm 150 is gasoline powered.
🛞 FULL-SIZE 19"/16" WHEELS
The Storm 150 uses:
FRONT
70/100-19
REAR
90/100-16
The larger front wheel helps the bike roll over uneven terrain, while the 16-inch rear wheel provides traction on appropriate dirt surfaces.
The 19"/16" wheel combination also contributes to the Storm's taller full-size riding position. (XProUSA)
🏁 INVERTED HYDRAULIC FRONT FORKS
The front suspension uses:
Φ45 × Φ48 × 780mm INVERTED HYDRAULIC FORKS
The inverted configuration is designed to provide a more substantial front suspension structure than conventional telescopic forks.
🔧 REAR SUSPENSION
At the rear is:
12 × 315mm NON-ADJUSTABLE SHOCK
The front and rear suspension work together to absorb bumps and uneven surfaces encountered during recreational off-road riding.
🛑 HYDRAULIC DISC BRAKES
The Storm 150 uses hydraulic disc braking at both wheels.
FRONT
220mm disc
Hydraulic dual-piston caliper
REAR
190mm disc
Hydraulic single-piston caliper
This gives the Storm dedicated braking hardware at both ends rather than a drum-brake setup. (XProUSA)
🧱 PERIMETER CRADLE STEEL FRAME
The Storm 150 is built around a:
PERIMETER CRADLE TYPE STEEL FRAME
The frame is designed to provide rigidity and stability during acceleration, braking and recreational off-road riding.
The full-size chassis incorporates:
-
52.8" wheelbase
-
35" seat height
-
12.6" ground clearance
-
181 lb net weight
-
176 lb listed maximum load capacity
⛰️ 12.6" GROUND CLEARANCE
The Storm 150 provides:
12.6 INCHES OF GROUND CLEARANCE
That helps provide room beneath the chassis when riding over appropriate:
-
Dirt
-
Gravel
-
Ruts
-
Roots
-
Uneven trails
-
Farm/private-property terrain
X-PRO does not publish an official maximum hill angle, so no unsupported climbing percentage is claimed.
📏 35" SEAT HEIGHT
The Storm 150 has a:
35-INCH SEAT HEIGHT
Combined with the 19"/16" wheels, this creates a full-size riding position intended for bigger riders.
Actual rider fit depends on inseam, footwear, riding position and experience.
⛽ 6-LITER FUEL TANK
The Storm carries:
6 LITERS
of gasoline.
X-PRO does not publish a guaranteed miles-per-tank range, so range should not be presented as a fixed number.
Actual fuel consumption depends on:
-
Rider weight
-
Speed
-
Terrain
-
Gear selection
-
Throttle use
-
Riding style
-
Engine operating conditions
💡 BUILT FOR OFF-ROAD RIDING
The Storm 150 includes an:
🔴 ENGINE KILL SWITCH
and:
🦶 FOOT BRAKE
The current product specification does not list a full lighting package for this base Storm 150.
This is important when comparing it with the more expensive Storm DLX, which adds full lighting equipment. (XProUSA)

Important specification note: X-PRO's current base Storm 150 page lists 176 lbs as the maximum load capacity. The separate Storm DLX 150 page lists 209 lbs. These are different models, so the Storm 150 should be advertised at 176 lbs maximum load, not 209 lbs. (XProUSA)
🏎️ PERFORMANCE
⚡ 6.8 kW POWER
The Zongshen 145cc engine produces:
6.8 kW @ 7,500 ±500 RPM
That's approximately 9.1 horsepower when converting 6.8 kW to mechanical horsepower.
💪 11 N·m TORQUE
Maximum torque is:
11 N·m @ 5,500 ±500 RPM
The 4-speed manual transmission lets the rider manage this output through different gears.
🚀 65+ MPH
The manufacturer's published maximum is:
65+ MPH
Actual speed varies according to rider weight and road conditions. (XProUSA)
⛽ RANGE
The Storm has a:
6 LITER FUEL TANK
X-PRO does not publish a guaranteed miles-per-tank figure.
Therefore, actual range should be determined by real-world fuel consumption rather than marketed as a fixed mileage number.
⛰️ HILL CLIMBING
X-PRO does not publish a maximum hill-grade specification.
The Storm's:
6.8 kW output
11 N·m torque
4-speed manual transmission
#428 chain
and 12.6" ground clearance
give it a suitable mechanical configuration for recreational trail climbing, but actual climbing performance depends heavily on rider skill, surface, gear selection and conditions.
🌲 TERRAIN CAPABILITY
The 19"/16" tires, 12.6" ground clearance and full-size chassis are suited to appropriate:
-
Dirt trails
-
Gravel
-
Grass
-
Farm/private-property riding
-
Recreational OHV terrain
-
Uneven off-road surfaces

The Storm DLX comparison is particularly useful: it uses the same basic 145cc/6.8 kW/11 N·m/19"/16" platform but adds the upgraded lighting package and lists a 209 lb maximum load, whereas the base Storm lists 176 lbs. (XProUSA)
Other 150cc options in the same market include the X-PRO Hawk 150, Viper 150 and Thunder 150, which are also offered with 19"/16" wheel configurations.
🏆 WHY THE STORM 150?
