2021 Honda CRF110F overview

The 2021 Honda CRF110F is Honda's kid-size trail bike, the next step up from the CRF50F. It has a fuel-injected, air-cooled 109cc single with a SOHC two-valve head, electric start with a backup kickstarter, and a four-speed gearbox with an automatic clutch, so there is no clutch lever. A twin-spar steel frame carries a 31 mm fork, a single rear shock and drum brakes front and rear, on 14-inch front and 12-inch rear wheels, and a throttle limiter lets a parent cap engine speed while a new rider learns. Mechanically the 2021 is the same as the 2019, when this generation was introduced. It came in red.

Who it's for

Young riders moving up from a smaller bike such as the CRF50F who aren't ready for a manual clutch: the automatic clutch, low 25.9-inch seat and adjustable throttle limiter let them learn at their own pace. Honda's weight limit is 132 lb, rider and gear included. It is for off-road use only, carries one rider, and has no lights.
