The CRF150R. Two sizes, one purpose: Domination. There's nothing small about the size of its performance. Honda s CRF150R is, hands down, the best MX machine in the Mini Class. Designed around a four-stroke powerplant that showcases plenty of Honda technology, we ve given it some major-league upgrades for 2012, and graced it with the performance that will keep you up at the front of the pack and on the podium. First, a new cylinder head, new cam, and new piston help this CRF150R run more consistently at different tracks, different elevations and different temperatures. An improved direct push accelerator pump gives you better, more immediate throttle response. New suspension valving returns improve action on small bumps but keeps the 150 s excellent large-bump performance. And finally, the CRF150R is available in two versions to fit a wider variety of riders. The CRF150R. For aspiring racers it s just what every motocrosser wants. A great start. And one that just about ensures great finishes.
