History of the Honda Zoomer
Rugged by design

The Zoomer differs from more traditional scooters with its rugged design, including fatter tyres with deeper tread and a skeletal frame that lacks an enclosed storage compartment. The NPS50 shares similar motor and drivetrain components with the CHF50.
European fuel injection
The Zoomer sold in European countries features a compact single-point programmed fuel injection system consisting of a single fuel injector, a different fuel pump arrangement and an oxygen sensor fitted just before the exhaust silencer.
Economy
Honda claims that the Ruckus returns 114 miles per US gallon in EPA tests.
