2005 YAMAHA PW 50, CALL NOW!!! - Spoil 'Em While You Can Yes we suppose it does resemble a puppy, but don't be fooled. The scrappy PW50 is also the rugged little motorcycle that's taught thousands of riders the Code of Moto. (And thousands more to follow, judging by the way these inexhaustible little bikes get handed down to younger siblings and the kid next door.) We couldn't be prouder, really. Here are the features that make the PW50 so popular. Full-auto transmission 19.1-inch seat height 82-pound dry weight Low-maintenance shaft drive Autolube oil injection Quiet spark arrestor-equipped exhaust ... the precocious PW50 is the perfect lead-in to a lifetime of two-wheeled fun. Too bad it's kind of hard to see those huge smiles inside the helmets, but you know they're grinning.
