3. Motorcycles and ATVs are motor-powered machines, not toys or other articles kids wear or play with, so the extent and nature of children's interaction with the products is materially different. As Congress knows, kids do not lick tailpipes or swallow battery terminals. Young riders typically only touch a few parts of the vehicles, like handlebars and brake and clutch levers, and usually with gloved hands.
4. ATVs and dirt bikes are stored outside the house, usually in garages, sheds or barns, and thus are much less likely than household items to be touched by young children. In addition to being remotely located, the vehicles have keys and use is controlled and supervised by parents.
