1992 | SW-1

New concept model described as humanware


Born from the Tokyo Creative movement, which aimed to develop new products for the 21st century, the SW-1 was exhibited at the 1991 Tokyo Motor Show as an inspirational model and attracted many favorable comments. Developed under the concept of casual cruising from city streets to the big outdoors, it features a sleek and fully covered chassis that realizes a perfect harmony with its surroundings, whether in town or in the suburbs. Its unique and curvaceous styling delivers an impression of high refinement. The 250 cm³ air-cooled 4-stroke 1-cylinder engine is paired with an oil cooler and realizes a superb balance between ample torque and rideability. The belt-driven drivetrain is extremely quiet and easy to maintain, and a seesaw-type gear shift pedal was adopted to protect the instep of the rider’s shoe. The SW-1 received the 1992 Good Design Award.
