2013 Honda CRF 150R Expert, Small Bike, Big Trophies. The CRF150R may be Hondas smallest MX machine, but it has everything it needs to be a big winner. Consider the Honda CRF150Rs high-performance Unicam® engine with lightweight counterbalancer shaft and drive gears. Or its fully adjustable Showa® suspension to smooth out bumps while maintaining a high level of wheel control. And a Pro-Link® rear suspension just like the big boys. In short, even though its designed for smaller racers, its big on the features you expect from a Honda. The CRF150R. For aspiring racers its just what every motocrosser wants. A great start.
