If you're young and missed the incubus of our sport, some mention of the character of these bikes is in order, and may help you regret it less. Among the finest off-road machines of its day, the Ossa Pioneer finished second only to Suzuki's TS250 in Cycle magazine's '71 enduro shootout. It's an old-school piston-port two-stroke with a pussycat of a powerband, a huge brass flywheel, tons of ground clearance and surprisingly decent Betor fork. But the short-travel rear suspension stinks, as does the narrow seat, rude left-side kickstarter, lazy half-turn throttle and a carb that floods quicker than the St. Bernard Parish. It looks like an orange rattletrap of death, my teenager said, but the challenge of riding it made it almost as much fun as a modern bike.
