Kawasaki MEGURO S1 / Overview

The Meguro brand plays an important role in the history of Kawasaki motorcycles. Meguro Manufacturing, the birthplace of the Meguro brand’s century-long history, is one of Japan’s oldest motorcycle manufacturers, founded in 1924 (Taisho 13) in what is now Shinagawa Ward, Tokyo. While most motorcycles in the 1920s were focused on practicality, Kawasaki offered motorcycles that emphasized the joy of riding. After World War II, the company released the Meguro J (Junior) with a 250cc single-engine, pioneering the 250cc class in Japan. Even in the early days of postwar racing, Meguro’s single-engine models fully demonstrated their sporty performance. They achieved excellent results, including first and second place in the 500cc class at the 2nd Asama Volcano Race in 1957. In 1964, Meguro Manufacturing merged with Kawasaki Aircraft (now Kawasaki Motors Corporation). That lineage continues to live on in Kawasaki motorcycles today.

In 1964, the Kawasaki 250 Meguro SG was released, bearing both the Meguro and Kawasaki brand names.

The Kawasaki 250 Meguro SG retained the distinctive style of the Meguro J (Junior) while featuring a more powerful 248cc engine. This bike continued the Meguro lineage, boasting both excellent engineering and styling. Sixty years later, in 2024, the Meguro S1 returned to the 250cc class.

At first glance, the MEGURO S1 is instantly recognizable as a legitimate successor to the Meguro. Its black coloring, chrome-plated fuel tank, and three-dimensional “MEGURO” emblem identify it as a retro-classic Meguro model, carrying on 100 years of history and style. The classic Meguro look and feel are combined with the latest technology. The 232cc engine delivers torquey, linear power delivery across the entire rev range. It also boasts an easy-to-handle chassis and a low seat height.

The MEGURO S1 is the perfect model for anyone who loves the Meguro brand, allowing them to easily experience the world of Meguro.
