The Yamaha XS400 SECA, launched in 1981, was a sporty and stylish motorcycle that marked a significant shift in Yamaha's approach to the mid-range market. Unlike its predecessors, the XS400 SECA was designed with an emphasis on handling and performance, catering to a more demanding rider. It featured a newly designed, air-cooled, 4-stroke, 399cc, parallel-twin engine, which delivered smooth power and respectable performance for its class. The SECA also boasted a lightweight and agile chassis, with a telescopic front fork and dual rear shocks, resulting in nimble handling and responsive steering. Furthermore, the SECA boasted distinctive styling compared to its predecessors, featuring sharp lines, a sleek, aerodynamic fairing, and a distinctive two-tone paint scheme. These features, combined with its accessible price point, made the XS400 SECA a popular choice for both novice and experienced riders.

The Yamaha XS400 SECA was a departure from the traditional, utilitarian approach of the earlier XS series. It aimed to appeal to a younger, more style-conscious audience who were drawn to sportiness and performance. The SECA's success led to the development of the larger, more powerful XS650 SECA, which further solidified Yamaha’s commitment to this new, performance-oriented approach. Despite its popularity, production of the XS400 SECA ended in 1984, making way for newer models and leaving behind a legacy as a stylish and capable motorcycle that bridged the gap between practicality and performance. Today, the XS400 SECA remains a popular choice for restoration and customization projects, appealing to enthusiasts who appreciate its classic design and potential for personalization.
