🏁 X-PRO X9 125cc DIRT BIKE
6.3 kW • 8.8 N·m • 45+ MPH • 4-SPEED MANUAL • 17"/14" BIG WHEELS
The X-PRO X9 is a lightweight, full-size-style gasoline dirt bike built around a Zongshen 125cc 4-stroke single-cylinder engine producing 6.3 kW at 7,500 RPM and 8.8 N·m of torque at 5,500 RPM.
A 4-speed manual wet multi-plate clutch, pure kick start, 17"/14" knobby tires, 45mm inverted front forks, 220mm hydraulic disc brakes front and rear, and 13.58" of ground clearance give the X9 a focused off-road configuration for experienced teen and adult riders.
🔥 ZONGSHEN 125cc POWER
6.3 kW @ 7,500 RPM
The X9 uses a genuine Zongshen 125cc 4-stroke air-cooled engine.
Engine specifications
-
⚡ Displacement: 125cc
-
1️⃣ Cylinder: Single
-
❄️ Cooling: Air-cooled
-
⚡ Maximum power: 6.3 kW @ 7,500 RPM
-
💪 Maximum torque: 8.8 N·m @ 5,500 RPM
-
📐 Bore × stroke: 54 × 54 mm
-
🔧 Compression ratio: 9.0:1
-
⛽ Carburetor: PZ26 Jingke
-
🔥 Ignition: CDI
6.3 kW is approximately 8.4 horsepower when converted from kilowatts. The manufacturer publishes the engine's power as 6.3 kW, so that is the primary specification to use in advertising.
⚙️ 4-SPEED MANUAL WET CLUTCH
REAL RIDER CONTROL
The X9 uses a:
4-UP MANUAL CLUTCH TRANSMISSION
with a:
WET MULTI-PLATE CLUTCH
The rider controls:
-
Throttle
-
Clutch
-
Gear selection
-
Engine braking
Power reaches the rear wheel through a:
CHAIN DRIVE
This makes the X9 particularly suitable for riders who want to learn or continue developing genuine manual dirt-bike skills.
🚀 45+ MPH TOP SPEED
The X9 is rated for:
UP TO 45+ MPH
Actual top speed depends on:
-
Rider weight
-
Road/terrain conditions
-
Riding conditions
The X9 is therefore substantially more than a low-speed recreational mini bike, and riders should have appropriate experience before operating it.
🦶 PURE KICK START
The X9 uses:
KICK START ONLY
There is no electric starter and no starter battery.
That's important because the bike does not carry the additional weight or complexity of an electric-start system.
🔋 Battery
None
⚡ EV Propulsion Battery
Not applicable
⏱️ Charging Time
Not applicable
The X9 is powered by gasoline, not electricity.
🛞 BIG 17"/14" OFF-ROAD WHEELS
The X9 uses:
FRONT
70/100-17"
REAR
90/100-14"
Both are knobby tube-type tires mounted on steel wheels.
The larger wheel package helps the X9 maintain clearance and roll across uneven dirt, roots and trail obstacles.
🏁 45mm INVERTED FRONT FORK
The front suspension features:
45 × 48 × 700mm INVERTED FORKS
The forks are:
Hydraulic
Inverted/USD
Non-adjustable
The inverted configuration gives the X9 a more substantial front suspension architecture than conventional basic telescopic forks.
🔧 275mm REAR SHOCK
At the rear:
Ø10 × 275mm SHOCK
The rear suspension is:
Non-adjustable
Together with the inverted front fork, the suspension system is designed for recreational dirt trails and appropriate off-road riding.
🛑 MATCHED 220mm HYDRAULIC DISC BRAKES
One of the X9's standout specifications is its symmetric braking setup.
FRONT
220mm hydraulic disc
Single-piston caliper
REAR
220mm hydraulic disc
Single-piston caliper
Having the same 220mm rotor size front and rear gives the X9 a distinctive braking configuration within the 125cc entry-level segment.
🧱 CRADLE-TYPE STEEL TUBE FRAME
The X9 is built around a:
CRADLE-TYPE STEEL TUBE FRAME
The frame supports a compact but substantial off-road chassis with:
-
42.32" wheelbase
-
32.7" seat height
-
13.58" ground clearance
-
151 lb net weight
-
209 lb maximum load
The relatively low 151 lb net weight is particularly useful when maneuvering the bike on tight trails or moving it after a fall.
⛰️ 13.58" GROUND CLEARANCE
The X9 provides:
13.58 INCHES OF GROUND CLEARANCE
That is a key off-road advantage.
The clearance gives the chassis more room over:
-
🪨 Rocks
-
🌳 Roots
-
🏜️ Ruts
-
🌲 Trail debris
-
🏁 Uneven dirt
The manufacturer specifically highlights the high clearance as part of the X9's trail-focused design.
📏 32.7" SEAT HEIGHT
The X9 has a:
32.7-INCH SEAT HEIGHT
The manufacturer recommends approximately:
5'0"–6'2" RIDER HEIGHT
with the important caveat that actual fit depends on inseam, footwear, riding posture and suspension sag.
⛽ 3.5-LITER FUEL TANK
The fuel system holds:
3.5 L / 0.92 GAL
and uses:
87 OCTANE GASOLINE
X-PRO does not publish a guaranteed miles-per-tank range.
Actual fuel range varies according to:
-
Rider weight
-
Terrain
-
Speed
-
Throttle use
-
Gear selection
-
Riding style
💡 PURE OFF-ROAD CONFIGURATION
The X9 intentionally comes without road-oriented equipment.
❌ No headlight
❌ No tail light
❌ No turn signals
❌ No horn
Night riding is not recommended.
This is an off-road-only dirt bike, intended for private land, designated OHV areas and motocross practice environments rather than public streets.
