Honda Zoomer

The Zoomer, designation NPS50, is a scooter developed by Honda and introduced in Japan and America in late 2002 for the 2003 model year. In Canada and the US, the scooter is marketed as the Ruckus. The Zoomer differs from more traditional scooters with its rugged design, including fatter tires with deeper tread and a skeletal frame lacking an enclosed storage compartment. The NPS50 shares similar motor and drivetrain components with the CHF50.
