Honda CRF50 F Dirt Bike: Thereӳ a good reason Hondaӳ CRF50F is probably the worldӳ most popular beginner bike. A whole bunch of great reasons, actually. First, its bulletproof engine develops the kind of smooth, easy-to-use power first-timers really need. Its three-speed transmission with automatic clutch is newbie-friendly, and its tough suspension stands up to the use (and abuse!] of first-time riders. The CRF50F has features like an adjustable throttle limiter so you can tailor the power to your riderӳ skills. That kind of thoughtful engineering, long-term overall quality and a whole lot more are what make the CRF50F a Honda.
