Where it rides

Track—

The 2010 Honda CRF50F is Honda's smallest dirt bike, a trail bike for young children learning to ride. It has an air-cooled 49cc four-stroke single with an SOHC two-valve head and a carburetor, a kickstarter, and a three-speed gearbox with an automatic clutch, so there is no clutch lever. A steel frame carries a telescopic fork with 3.8 in of travel, a single rear shock with 2.8 in, and drum brakes front and rear, on 10-inch wheels. The seat is 21.6 in high, it weighs 110 lb ready to ride, and a throttle limiter lets a parent cap its speed. Honda didn't sell a 2010 CRF50F in the US (it returned there for 2011); the 2010 model was sold in Japan and New Zealand, the 2009 bike with pictogram switch labels.

Who it's for

Young children on their first motorcycle: the seat is just 21.6 in high, the automatic clutch means there is no clutch lever to learn, and the adjustable throttle limiter lets a parent cap the speed while a new rider learns. Honda's weight limit is 88 lb (40 kg), including the rider and any accessories. It is for off-road use only, carries one rider, and has no lights.
