🏁 X-PRO Leopard 40 Mini Dirt Bike
Compact 4-Stroke Performance. Easy Pull Start. Built for Off-Road Fun.
The X-PRO Leopard 40 DB-B07 is a compact gasoline mini dirt bike built around a 38.95cc single-cylinder, 4-stroke, air-cooled engine and a lightweight 48.4 lb net weight.
With a manufacturer-listed 25 MPH maximum speed, 1.1 kW power, 1.75 N·m torque, 2.50-10 tires, front and rear disc brakes, and a 23.6" seat height, the Leopard 40 is designed as a small recreational off-road bike for riders who fit within its 132 lb maximum load rating.
🔥 Small Size. Real Dirt-Bike Feel.
The Leopard 40 keeps the controls straightforward with a manual pull start, chain drive, simple 4-stroke engine, and compact chassis.
Why it stands out:
🏁 38.95cc 4-Stroke Engine
The SZ140QMA single-cylinder engine produces 1.1 kW at 7,000 rpm and 1.75 N·m at 5,500 rpm.
🪶 Only 48.4 lb Net Weight
The lightweight chassis makes the Leopard easy to maneuver for riders within the manufacturer's weight limits.
⚙️ Simple Chain Drive
The chain final drive provides a straightforward mechanical power transfer system.
🔑 Easy Pull Start
The manual hand-pull starter eliminates the need for an electric starting system.
🛑 Front & Rear Disc Brakes
Mechanical disc brakes are fitted at both ends for controlled stopping.
🛞 10-Inch Off-Road Tires
Both ends use 2.50-10 tires for a compact off-road setup.
🛡️ Speed Limiter
Parents can use the integrated speed limiter to restrict speed as appropriate for the rider.
🌲 8.66" Ground Clearance
The generous listed ground clearance helps provide clearance over suitable dirt and uneven surfaces.
⭐ Key Features
🔥 38.95cc 4-Stroke Engine
The Leopard 40 uses an SZ140QMA 38.95cc single-cylinder, 4-stroke, air-cooled engine.
Published output:
1.1 kW @ 7,000 rpm
Maximum torque:
1.75 N·m @ 5,500 rpm
The 4-stroke configuration uses gasoline without adding oil directly to the fuel.
⚙️ Simple Chain Drive
The Leopard uses a chain-drive final drive.
The simple drivetrain keeps the motorcycle's mechanical layout straightforward and easy to understand.
🔑 Manual Pull Start
Starting is handled by a manual hand-pull starter.
There is no electric starter or propulsion battery.
This means:
Motor: Gasoline engine
Starter: Manual pull
Battery: None specified
Charging: Not applicable
🛑 Front & Rear Mechanical Disc Brakes
The Leopard 40 uses disc brakes on both wheels:
Front: Mechanical disc
Rear: Mechanical disc
This gives the bike independent braking systems at the front and rear.
🛞 2.50-10 Tires
The bike uses the same tire size at both ends:
Front: 2.50-10
Rear: 2.50-10
The 10-inch wheels keep the Leopard's overall package compact while providing an appropriate tire footprint for its mini-bike chassis.
🛡️ Adjustable Speed Control
A built-in speed limiter allows parents or supervisors to restrict the bike's speed.
This can be useful when a rider is developing throttle control and learning to operate the bike responsibly.
The manufacturer lists the maximum speed at:
25 MPH
Actual speed depends on rider weight and road conditions.
🏗️ Lightweight Compact Frame
The Leopard's compact chassis measures:
48.4" long × 23.6" wide × 30.7" high
The listed:
Net weight: 48.4 lb
Gross weight: 59.4 lb
This compact design makes the Leopard substantially smaller than full-size dirt bikes.
