Description
The Razor SX125 McGrath is no ordinary children’s toy. It is a meticulously engineered, 12V electric mini dirt bike that brings real motocross excitement to riders as young as five years old. Endorsed and inspired by the legendary Jeremy McGrath — the 7-time AMA Supercross World Champion widely known as the “King of Supercross” — this bike carries championship credentials right into your child’s back garden.
Features:
- 100W High-Torque Motor Chain-driven electric motor delivers smooth, consistent power for confident acceleration on garden paths, grass, and dirt tracks.
- Long-Life 12V Battery Sealed lead-acid rechargeable battery provides up to 80 minutes of continuous riding on a single charge in Low Speed Mode — hours of outdoor fun.
- Dual Speed Modes Parent-controlled High/Low speed switch, set the ideal maximum speed for your child’s age and ability, Low Speed up to 8 km/h, High Speed up to 13 km/h.
- 12″ Pneumatic Knobby Tyres 305mm off-road style rubber tyres with deep tread patterns grip uneven surfaces, providing stability and control on grass, dirt, and gravel terrain.
- Authentic Steel MX Frame Genuine motocross-style steel frame with real dirt bike geometry — sturdy, lightweight, and engineered for dynamic off-road performance.
When Razor partnered with Jeremy McGrath to create the SX125, it wasn’t just about adding a name to the product. The result is a bike that reflects McGrath’s authentic motocross heritage — from the aggressive frame geometry to the striking graphics that mirror the aesthetic of professional race machines. Your child won’t just be riding a toy; they’ll be riding a piece of motocross history.
Built for Real Off-Road Adventure
The Razor SX125 McGrath isn’t just about looks. Every feature has been carefully developed to provide young riders with a safe, thrilling, and confidence-building experience — both on flat surfaces and uneven terrain.
Builds Confidence from the First Ride
The dual speed control system means parents can start their child on the safer, lower maximum speed (8 km/h) before progressing to High Speed mode (13 km/h) as confidence and skill develop. This gradual progression makes the SX125 ideal for complete beginners and more experienced young riders alike.
Encourages Active Outdoor Play
In an age of screens and indoor entertainment, the SX125 gives children a compelling reason to step outside. Research consistently shows that active outdoor play improves physical fitness, motor skills, spatial awareness, and mental wellbeing — and the SX125 makes every garden session feel like a genuine adventure.
Develops Core Motor Skills
Riding the SX125 requires hand-eye coordination (throttle and brake), balance, spatial judgement, and body control. These are fundamental skills that benefit children far beyond the motocross circuit — in sports, school, and everyday life.
Zero Emissions — Quiet & Neighbour-Friendly
Unlike petrol-powered alternatives, the SX125’s electric motor produces zero emissions and operates at a fraction of the noise level of combustion engines. Perfect for residential UK gardens and shared outdoor spaces — fun for your child without disturbing the neighbourhood.
Premium Brand Heritage
Razor has been the world leader in innovative ride-ons for over 20 years. Combining Razor’s engineering pedigree with the authentic endorsement of 7-time Supercross champion Jeremy McGrath, the SX125 represents the very best in children’s electric motocross bikes.
