🏁 X-PRO HAWK 125cc DIRT BIKE
6.3 kW POWER • 55 MPH • 4-SPEED MANUAL • 19"/16" FULL-SIZE WHEELS
The X-PRO Hawk 125cc is a full-size, gasoline-powered dirt bike built for riders who want a substantial off-road platform with a genuine manual clutch and large 19"/16" wheels. Its Zongshen 125cc 4-stroke single-cylinder engine produces 6.3 kW at 7,500 RPM and 8.8 N·m at 5,500 RPM, with electric and kick start for added convenience.
With a 4-speed manual transmission, perimeter cradle steel frame, 750 mm inverted hydraulic forks, hydraulic disc brakes, 11.8" ground clearance and 209 lb maximum load, the Hawk is designed for recreational off-road riding where rider control and full-size proportions matter.
🔥 REAL 125cc POWER. FULL-SIZE CONTROL.
⚡ ZONGSHEN 125cc 4-STROKE ENGINE
At the center of the Hawk is a Zongshen 125cc 4-stroke, single-cylinder, air-cooled engine.
Engine output
-
Maximum power: 6.3 kW @ 7,500 RPM
-
Maximum torque: 8.8 N·m @ 5,500 RPM
-
Compression ratio: 9.0:1
-
Bore × stroke: 54 × 54 mm
-
Carburetor: PZ26
-
Ignition: CDI
The Zongshen engine gives the Hawk a straightforward gasoline powertrain with a traditional motorcycle-style manual gearbox.
⚙️ 4-SPEED MANUAL CLUTCH
PUT THE RIDER IN CONTROL
The Hawk uses a:
4-UP MANUAL CLUTCH TRANSMISSION
The rider controls the gears and clutch rather than relying on an automatic transmission.
Power reaches the rear wheel through:
#428 CHAIN • 13T/41T SPROCKETS
This setup gives experienced riders more control over acceleration and engine speed across changing terrain.
🚀 55 MPH TOP SPEED
The manufacturer lists a maximum speed of:
55 MPH
Actual speed depends on rider weight and road conditions.
At 55 MPH, this is a serious off-road motorcycle rather than a low-speed recreational toy. Riders should have appropriate experience and use proper protective equipment.
🔑 ELECTRIC + KICK START
The Hawk gives you two starting options:
⚡ ELECTRIC START
Convenient push-button starting.
🦶 KICK START
A mechanical backup when electric starting isn't available.
The starting system uses a:
12V / 4Ah battery
This is a starter battery, not an electric propulsion battery.
🛞 19"/16" BIG WHEELS
One of the Hawk's biggest advantages is its full-size wheel configuration.
FRONT
70/100-19"
REAR
90/100-16"
The larger 19-inch front wheel helps the bike roll over uneven terrain, while the 16-inch rear wheel provides traction and stability.
X-PRO specifically positions the larger-wheel design as a major advantage over smaller 125cc dirt bikes.
🏁 750mm INVERTED HYDRAULIC FRONT FORKS
The Hawk uses:
Φ45 × Φ48 × 750 mm inverted hydraulic forks
The inverted front suspension provides a substantial front-end design for a full-size dirt bike.
🔧 315mm REAR SHOCK
At the rear is a:
12 × 315mm non-adjustable shock
Together, the inverted front forks and rear shock are designed to absorb bumps and uneven off-road terrain.
🛑 HYDRAULIC DISC BRAKES
The Hawk uses dedicated hydraulic disc brakes at both ends.
FRONT
220mm disc
Hydraulic dual-piston caliper
REAR
190mm disc
Hydraulic single-piston caliper
The larger 220mm front disc provides strong braking leverage, while the 190mm rear disc completes the braking system.
🧱 PERIMETER CRADLE STEEL FRAME
The Hawk uses a:
PERIMETER CRADLE TYPE STEEL FRAME
The manufacturer describes the frame as an upgraded design intended to provide strength, rigidity and stability during acceleration and braking.
The steel frame supports the bike's full-size dimensions and 209 lb maximum load capacity.
⛰️ 11.8" GROUND CLEARANCE
The Hawk provides:
11.8 INCHES MINIMUM GROUND CLEARANCE
That gives the chassis useful clearance over:
-
Dirt
-
Gravel
-
Ruts
-
Roots
-
Uneven trails
-
Light trail obstacles
X-PRO does not publish a maximum hill angle, so no unsupported climbing figure is claimed.
⛽ 1.2-GALLON FUEL TANK
The Hawk carries:
1.2 gallons
of gasoline.
Because this is a gasoline motorcycle, there is no electric-bike range or propulsion-battery charging time.
Actual fuel range depends on:
-
Throttle use
-
Rider weight
-
Terrain
-
Gear selection
-
Riding speed
-
Engine tuning
💡 COMPLETE LIGHTING PACKAGE
The Hawk includes:
🔦 HEADLIGHTS
🔴 TAIL LIGHT
↔️ TURN-SIGNAL INDICATORS
📢 HORN
The lighting package gives the bike a more complete equipment specification than a stripped-down competition-only dirt bike.
🛡️ SAFETY & CONTROL
🔴 ENGINE KILL SWITCH
Allows the rider to shut down the engine quickly.
🦶 FOOT BRAKE
Dedicated foot-operated rear braking control.
🛑 FRONT + REAR HYDRAULIC DISCS
220mm front
190mm rear
💡 FULL LIGHTING
Headlight, tail light and turn indicators.
⚡ WHY THE HAWK 125cc?
🏎️ REAL MANUAL RIDING
The 4-speed manual clutch gives the rider direct control over gear selection and engine response.
💪 8.8 N·m OF TORQUE
The Zongshen engine produces 8.8 N·m at 5,500 RPM.
🛞 FULL-SIZE 19"/16" WHEELS
Large wheels help the Hawk handle uneven ground more confidently than compact mini-bike configurations.
🏁 55 MPH
A manufacturer-listed top speed suitable for experienced off-road riders.
🔧 INVERTED HYDRAULIC FORKS
The 750mm inverted front forks give the bike a substantial front suspension package.
🛑 HYDRAULIC BRAKING
A 220mm dual-piston front disc and 190mm single-piston rear disc provide dedicated braking at both wheels.
🔑 ELECTRIC + KICK START
Convenience when starting, plus a mechanical backup.
🧱 STEEL PERIMETER FRAME
Designed around rigidity and stability for recreational off-road riding.

🏎️ PERFORMANCE
🔥 6.3 kW ENGINE OUTPUT
The Hawk's Zongshen 125cc engine produces:
6.3 kW @ 7,500 RPM
That is approximately 8.4 horsepower when converting 6.3 kW to mechanical horsepower. X-PRO's product specification itself reports the engine output as 6.3 kW, rather than separately publishing a horsepower figure.
💪 8.8 N·m TORQUE
Maximum torque:
8.8 N·m @ 5,500 RPM
The 4-speed manual gearbox allows the rider to select gearing appropriate to acceleration and terrain.
🚀 55 MPH
The published maximum speed is:
55 MPH
Actual speed depends on rider weight and road conditions.
⛽ FUEL RANGE
The tank holds:
1.2 gallons
X-PRO does not publish a guaranteed miles-per-tank range, so range should not be represented as a fixed number.
⛰️ HILL CLIMBING
No official maximum grade is published.
The bike's 6.3 kW output, 8.8 N·m torque, 4-speed manual transmission, #428 chain and 11.8" ground clearance provide the hardware for recreational trail climbing, but actual climbing performance depends heavily on rider skill, gearing, surface and conditions.
🌲 TERRAIN CAPABILITY
The Hawk is best suited to:
-
Dirt trails
-
Packed earth
-
Gravel
-
Grass
-
Farm/private-property terrain
-
Recreational OHV environments
The 19"/16" tires and 11.8" ground clearance are particularly useful on uneven ground.

🏆 WHY CHOOSE THE HAWK?
The Hawk differentiates itself with its combination of:
6.3 kW engine output
8.8 N·m torque
Electric + kick start
19"/16" wheels
34" seat height
11.8" ground clearance
209 lb load capacity
220mm/190mm hydraulic discs
750mm inverted hydraulic forks
and a complete headlight, tail light, turn-signal and horn package.
🧑 RIDER FIT
The manufacturer does not publish a specific minimum age or rider-height range for this model.
Instead, the most important fit measurements are:
34" SEAT HEIGHT
209 LB MAXIMUM LOAD
52" WHEELBASE
The larger 19"/16" wheels also make this substantially larger than small-wheel 125cc dirt bikes.
Riders should be able to comfortably control a motorcycle with a 34-inch seat height and should have the maturity and experience appropriate for a motorcycle capable of 55 MPH.
