The approach begins with an easy-to-kickstart, four-stroke, air-cooled 49cc engine driving through an automatic clutch and three-speed manual transmission. The original pint-sized Mini Trail was a hardtail, but the latest CRF50F has monoshock rear suspension backing up a simple inverted fork with 3.5 inches of travel. Not exactly Supercross-caliber stuff, but that’s unnecessary for buzzing around the backyard or campground. Safety features include an adjustable throttle limiter, protective chain guards, and an ignition key that keeps the littlest CRF off-limits while you’re at work. What the heck, dad!
