The award-winning CRF150RB packs genuine high-performance four-stroke power into a mini racer with a bigger 19 inch front wheel.
Younger racers may be smaller in stature, but that doesn’t mean they can’t have a giant-sized heart for racing—and winning. So for these younger racers, Honda designed the CRF150RB as an integral part of the CRF® racing lineup.
The bigger wheel size of the CRF150RB, 19 inch front and 16 inch rear, will be ideal for the taller kids.
