Honda Zoomer

The Honda Zoomer NPS50 (in North America Honda Ruckus ) is a single-seat scooter from the Japanese manufacturer Honda . It was launched in Japan and the USA in 2002, and in Europe in 2004; In 2012 Honda stopped selling.

Technical details

The scooter is powered by a liquid-cooled single-cylinder four-stroke engine with 50 cm³ displacement, overhead camshaft and electronic fuel injection and has a regulated catalytic converter . Consumption is around 2.2 liters of regular petrol per 100 km. The North American model has a carburetor with choke and no catalytic converter instead of injection . Due to its design, the zoomer does not achieve the liveliness of similar scooters with two-stroke engines. In the EU version it is increased to a maximum speed of max. 42–45 km / h restricted. A throttling to max. 25 km / h is possible.

An electronic starter with a brushless alternator was an innovative novelty that made a separate starter motor superfluous. The light, maintenance-free and magnetically driven water pump works without mechanical seals. The continuously variable, fully automatic Honda V-Matic V-belt transmission is maintenance-free. The chassis can also handle light off-road trips. The equipment of instruments is limited to the bare essentials, tachometer, fuel gauge and clock are missing. There is no weather protection, only the wide running board protects something from splashing water from below. The arrangement of the frame and handlebars allows tall riders to sit comfortably over long distances. The low weight makes it easy to maneuver the scooter, and jacking it up on the main stand is easy.

The model is very popular in the USA and Japan, where it is often extremely modified and increased in performance. Honda itself offered accessories to customize the scooter. There are accessories from other manufacturers.

Honda Zoomer

In Germany, the model could not establish itself due to its high price and unusual design, despite its technical features. Honda stopped selling the scooter at the end of 2012.

To operate the Honda Zoomer on public roads in Germany, the ABE and the annually (March 1st) changing moped insurance license plate as well as at least the driving license class AM (at Vmax 25 km / h: moped test certificate) are sufficient.

No separate driving license is required in Austria, except for a moped license for 15-year-olds. Moped license plates and insurance as well as the related annual §57a “Pickerl” assessment are mandatory.
