Rider Profile

Best ForThis is a starter minibike built for young children just learning to ride, not for any rider with prior road experience.
PurposeIts purpose is supervised backyard and trail introduction to motorcycling, with an automatic clutch and tiny 49.5cc engine to keep speeds very low and safe.
Rider FitThe extremely low 21.6-inch seat height and 111 lb wet weight make it sized exclusively for small children, not teens or adults.
CharacterIt's a friendly, forgiving little machine with a 3-speed automatic-clutch gearbox and drum brakes designed to build confidence rather than deliver performance.
Not Ideal ForThis is not for anyone seeking real speed, distance capability, or a bike that fits an adult-sized rider.

Character map is an editorial estimate based on this bike's specifications, not a lab-tested measurement.

2018 Honda CRF50F Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 549mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2018 Honda CRF50F, with a cramped knee angle of around 45 degrees and a slightly forward riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
