Petrol motocross: why choose petrol?
A petrol motocross bike for kids offers unlimited range (as long as the tank is full), an authentic engine sound, and a riding experience identical to an adult's — just scaled down. It's the preferred choice for future amateur racers who want to train regularly on circuit.
Safety and protective gear
Full-face helmet, gloves, high boots, and body protection are essential for motocross, even in kids' models. Adult supervision is required at all times. Browse our kids helmets.

2-stroke or 4-stroke: which engine for a kids motocross bike?
Small displacements (49cc) are typically 2-stroke: lighter, punchier, but require a petrol-oil mix. From 70-110cc, 4-stroke becomes common: simpler maintenance (petrol only), smoother riding — recommended for beginners.
What motocross size for your child's height?
As with quads, seat height should let your child touch the ground with their tiptoes. For ages 6-7, choose a 10" wheel; for ages 8-9, a 12" wheel; and from age 10, a 14" wheel like the Drizzel URX 125cc.
Maintaining a petrol motocross bike for kids
Regular maintenance includes: oil changes (10W-40 or 2-stroke mix depending on the engine), air filter cleaning/replacement, spark plug checks, chain tension. All common parts are available in our parts section.
