SYX MOTO VK 58cc 4-Stroke Mini Dirt Bike
🏁 REAL 4-STROKE PERFORMANCE. BUILT FOR OFF-ROAD ADVENTURE.
A premium mini dirt bike for young riders who are ready to ride.
The SYX MOTO VK combines a genuine 57.6cc 4-stroke gasoline engine, fully automatic transmission, front and rear disc brakes, and full suspension into a compact off-road package designed for riders 12 years and older.
With 2.0 HP, a claimed top designed speed of 21.75 MPH, up to 62 miles of maximum range, and a 143 lb maximum load, the VK is designed to provide an approachable introduction to recreational dirt-bike riding.
⚡ WHY THE VK STANDS OUT
🏍️ Genuine 57.6cc 4-Stroke Engine
The VK uses a 57.6cc single-cylinder, air-cooled, 4-stroke engine producing 2.0 HP.
Unlike a 2-stroke engine that requires a fuel/oil mixture, the VK runs on 87# gasoline and uses splash lubrication.
Why it matters:
Simple operation, familiar gasoline fueling, and a 4-stroke engine platform designed for recreational off-road use.
🔥 21.75 MPH Top Designed Speed
The VK is rated for a top designed speed of 21.75 MPH (35 km/h).
Its speed governor and fully automatic drivetrain make it easier for newer riders to concentrate on steering, braking, and riding technique.
⛽ Up to 62-Mile Maximum Range
The 2.1-liter / 0.55 US gallon fuel tank is rated for a maximum range of up to 62 miles / 100 km.
Actual range will vary with rider weight, terrain, speed, riding conditions, and other factors.
⚙️ Fully Automatic Transmission
No manual clutch and no traditional gear shifting.
The VK uses an infinitely variable automatic transmission with chain drive, making the controls straightforward for riders learning the fundamentals of off-road riding.
🛞 10-Inch Off-Road Tires
The bike uses 2.50-10 front and rear tires mounted on 1.4-10 integral aluminum rims.
The combination provides a compact dirt-bike footprint while maintaining useful ground clearance for recreational off-road riding.
🛠️ Front & Rear Suspension
The VK features:
-
Inverted front shock absorber
-
Inner-oil-press rear shock absorber
With 9.44 inches / 240 mm of ground clearance, the chassis is designed for off-road environments rather than ordinary pavement use.
🛑 Front & Rear Disc Brakes
Both ends use disc brakes.
That gives the rider braking hardware at both the front and rear rather than relying on a single rear braking system.
🧱 Steel Chassis Construction
The VK uses a 195# steel pipe fully enclosed frame, a steel handlebar, steel swing arm, and steel footpegs.
The triple clamp is made from cast aluminum.

🏁 PERFORMANCE
57.6cc 4-Stroke Power
At the heart of the VK is a 57.6cc single-cylinder, air-cooled, 4-stroke gasoline engine rated at 2.0 HP.
The manufacturer specifies a 21.75 MPH / 35 km/h top designed speed.
A third-party specification listing reports 2 Nm of torque, although SYX MOTO's official specification table does not publish a torque rating. We therefore do not represent 2 Nm as an official SYX torque specification.

Hill Climbing
SYX MOTO does not publish a maximum hill grade, climbing angle, or official hill-climbing percentage for the VK.
For that reason, we do not advertise a specific hill-climbing angle.
Actual climbing performance depends on rider weight, terrain, surface conditions, tire pressure, incline, and riding technique.
Terrain Capability
The VK is intended for off-road recreational riding.
Its suspension, ground clearance, knobby-style 10-inch tires, and steel chassis make it more appropriate for dirt and recreational trails than normal street riding.
It is not a street-legal motorcycle and should only be operated where permitted by applicable laws and property rules.

Where the VK Fits
The MotoTec Warrior 52cc is lighter and slightly faster, but its 52cc 2-stroke engine requires a 25:1 gasoline/oil mixture and its published cruising range is 10+ miles per tank.
The Razor MX125 is substantially smaller and lighter with a 100W electric motor, 12V battery, and maximum speed of 8 MPH, making it more of a low-speed introductory electric ride.
The VK's combination of a 57.6cc 4-stroke engine, 2.0 HP, fully automatic transmission, front/rear disc brakes, full suspension, 10-inch tires, 143 lb payload, and 21.75 MPH top designed speed places it firmly in the recreational mini gas dirt-bike category.
🛡️ BUILT FOR CONTROL
The VK includes several features intended to make operation more manageable for newer riders:
🔴 Kill Switch
Provides a straightforward way to shut down the engine.
🎚️ Speed Governor

Both wheels use disc braking hardware for controlled stopping.
🔗 Covered Chain System
The design incorporates chain protection intended to help shield the drivetrain.

The manufacturer lists a top designed speed of 21.75 MPH / 35 km/h.
Actual speed can vary depending on rider weight, terrain, conditions, and setup.

SYX MOTO lists a maximum range of 62 miles / 100 km.
Real-world range can vary significantly based on riding conditions and rider weight.

The specification lists 87# gasoline.
The VK's 4-stroke design does not require the 25:1 gasoline/oil mixture used by the MotoTec Warrior 52cc 2-stroke.
5. Is the VK automatic?
Yes. It uses an infinitely variable-speed automatic transmission, so the rider does not have to manually shift gears or operate a clutch.
6. What age is the VK designed for?
SYX MOTO recommends the VK for riders 12 years old and older, with a maximum load of 143 lb / 65 kg.
Age alone should not determine suitability. Rider size, experience, maturity, protective equipment, supervision, and riding environment also matter.

Always ride only on terrain appropriate for the rider's ability and the vehicle.
9. Can it climb hills?
The VK's 2.0 HP 57.6cc 4-stroke engine is designed for recreational off-road use, but SYX MOTO does not publish a specific maximum hill angle or gradeability rating.
Hill performance depends heavily on rider weight, slope, surface, traction, and riding conditions.
10. Is it waterproof?
No waterproof or IP rating is published for the VK.
It should not be treated as waterproof or intentionally ridden through deep water, flooded areas, or conditions that could damage the engine, electrical components, drivetrain, or other systems.
11. Does it require assembly?
Yes. The bike is approximately 85% pre-assembled.
The manufacturer indicates that the rear shock absorber, front wheel, handlebar, and fender need to be installed.
12. Is it street legal?
No. The manufacturer describes the VK as an off-road recreational vehicle and states that it is not street legal.
Always check applicable local laws and property rules before operating.
⚠️ IMPORTANT SAFETY INFORMATION
This is a real gasoline-powered recreational vehicle, not a conventional electric toy.
