🏁 SYX MOTO K1 125cc Dirt Bike

Real 4-Stroke Performance. Manual Control. Built for the Trail.

Meet the SYX MOTO K1 125cc 4-Stroke Dirt Bike — a full-size off-road machine designed for riders who want genuine manual motorcycle control without stepping into a larger displacement bike.

With a 125cc air-cooled single-cylinder 4-stroke engine, 4-speed manual transmission, 50.0 MPH top designed speed, 123.4-mile maximum mileage, electric + kick start, hydraulic disc brakes, 17-inch front / 14-inch rear tires, and 12.8 inches of ground clearance, the K1 is built for recreational trail riding, private-property riding, and closed-course off-road use.

🔥 Built for Riders Who Want More Control

The K1 isn't an automatic ride-on. Its 4-speed manual transmission and chain drive give riders direct control over how the 125cc engine delivers power.

Whether you're learning clutch control, exploring private trails, riding around a recreational property, or practicing off-road technique, the K1 combines approachable 125cc performance with a rugged steel chassis.

Why riders choose the K1

⚙️ 125cc 4-Stroke Engine
A single-cylinder, air-cooled 4-stroke gasoline engine provides straightforward off-road performance without the complexity of an electric drivetrain.

🎮 4-Speed Manual Transmission
The manual gearbox lets the rider select from four forward speeds and manage engine response according to terrain and riding conditions.

⚡ Electric + Kick Start
Start the K1 with the electric starter or use the kick-start backup when preferred.

🛑 Hydraulic Disc Brakes
Hydraulic disc brakes are fitted at both the front and rear for controlled braking on off-road surfaces.

🌲 12.8-Inch Ground Clearance
The 325 mm / 12.8-inch clearance helps the chassis clear rocks, roots and uneven sections of trail.

🛞 17-Inch Front + 14-Inch Rear Tires
The 70/100-17 front and 90/100-14 rear tires provide a full-size off-road stance suited to dirt, gravel, grass and other recreational terrain.

🏗️ Steel Frame
A steel frame provides the rigid chassis foundation needed for recreational off-road riding.

⛽ 4.3L Fuel Tank
The 4.3-liter / 1.14-US-gallon tank supports extended recreational riding between fuel stops.

🚀 Performance That Feels Like a Real Dirt Bike

125cc Air-Cooled 4-Stroke Engine

The K1 uses a 125cc single-cylinder, 4-stroke, air-cooled gasoline engine with a 52.4 mm bore and 9:1 compression ratio.

The manufacturer specifies a top designed speed of 50.0 MPH / 80.48 km/h.
