Press Release, January 20, 1989 - Honda releases two types of road sports bike "Honda NS50F" with dual headlights

Honda Motor Co., Ltd. will release an even more fearless version of the Honda NS50F, a popular road sports bike with a large body and full-fledged equipment despite being 50cc, with dual headlights that give it an even more aggressive look and a new color scheme from February 15, 1989, and a Rothmans color specification (limited edition) from January 21 of the same year.

The new NS50F engine is a water-cooled, two-stroke, single-cylinder engine that is easy to handle from low and mid-range to high-range and has a powerful output characteristic (7.2PS/10,000rpm). The half fairing equipped on the large frame body is newly equipped with a lens-integrated dual headlight (pale yellow krypton bulb, 18W/18W x 2). In addition to the basic design suitable for long-distance touring, it has also improved usability for night driving.

The coloring design is set to two colors: "Red & White" inspired by HRC racers and "Dark Blue Metallic" color of the Seed Racing Team. At the same time, "Blue & White" color of the Rothmans Honda team is set as a limited coloring model, further enhancing the authentic sports mood.
