DS250784-000476

Kickstart their off-road adventures with the Razor MX125 Dirt Rocket, a compact electric motocross bike built for young riders aged 7 and up. Expertly scaled for beginners, this youth electric dirt bike delivers a confident, realistic ride with an authentic motocross frame that mirrors full-size bikes. It is the ideal first step into trail riding, weekend backyard fun, and outdoor play, blending kid-friendly performance with dependable safety.

The MX125 pairs a reliable chain-driven motor with a 12-volt rechargeable battery to provide smooth, consistent power. Riders can reach a manageable top speed of up to 8 mph (13 km/h), striking the perfect balance between excitement and control. With up to 40 minutes of continuous run time per charge, kids get plenty of ride time to build skills and enjoy off-road freedom.

Engineered for dirt tracks, paths, and grassy areas, the MX125’s 12-inch pneumatic knobby tyres deliver the traction young riders need on uneven terrain. The twist-grip throttle offers intuitive acceleration, while the hand-operated rear drum brake ensures predictable, controlled stopping. Riser-style handlebars enhance comfort and control, helping new riders feel at ease from the first twist of the throttle.

A lightweight yet durable steel frame keeps the bike easy to handle without sacrificing toughness, making it a smart choice for families seeking a beginner-friendly electric motocross bike that stands up to everyday play. From backyard laps to park trails, the Razor MX125 Dirt Rocket brings the thrill of off-road riding to kids in a safe, confidence-building package.
