**Suzuki SP400 Motorcycle 1979-1982**

**Introduction**

The Suzuki SP400 Motorcycle, produced from 1979 to 1982, was a revolutionary two-wheeler that marked a significant milestone in the history of motorcycling. With its advanced engineering, impressive performance, and distinctive styling, the SP400 quickly gained a reputation as a formidable force on the roads.

**Engine Design and Performance**

At the heart of the SP400 lay a liquid-cooled, parallel-twin engine of 393cc displacement. This powerplant featured a cutting-edge "Square Four" configuration, characterized by a compact cylinder arrangement with an equal bore and stroke measurement. The innovative design resulted in remarkable power output and exceptional throttle response, delivering a thrilling riding experience.

The SP400's engine was meticulously crafted with advanced metallurgy and precision engineering. Its dual-overhead camshafts, four-valve cylinder heads, and electronic ignition system ensured optimum combustion efficiency and maximum power extraction. With a generous compression ratio of 10.2:1, the bike boasted an impressive power output of 39 horsepower at 9000 rpm, making it one of the most potent machines in its class.

**Chassis and Suspension**

To complement its impressive powertrain, the SP400 incorporated a rigid and lightweight chassis constructed from high-tensile steel. The frame's carefully calculated geometry provided excellent stability and cornering precision, enhancing the bike's overall handling characteristics.

The SP400's suspension system was equally advanced, featuring a conventional telescopic front fork with hydraulic shock absorbers and a linked rear suspension with a Monoshock. This setup provided a smooth and controlled ride, ensuring both comfort and precise handling on a variety of road surfaces.

**Braking System**

The SP400 was equipped with a robust and efficient braking system designed to provide maximum stopping power. The front wheel featured a twin-disc setup with floating calipers, while the rear wheel boasted a single disc brake. These brakes offered excellent feel and modulation, allowing riders to maintain precise control in all riding conditions.

**Styling and Ergonomics**

The Suzuki SP400's striking styling set it apart from its contemporaries. Its sculpted bodywork, angular fairing, and aggressive stance exuded a sporty and dynamic character. The bike's aerodynamic design not only reduced wind resistance but also enhanced its stability at high speeds.

The SP400's ergonomics were carefully engineered to provide a comfortable and engaging riding position. Its well-positioned handlebars, low seat height, and sculpted seat design ensured a natural and harmonious connection between rider and machine.

**Legacy and Impact**

The Suzuki SP400 Motorcycle made a profound impact on the motorcycling world. Its innovative engine design, advanced chassis, and impressive performance redefined the standards of the time. The bike quickly gained a loyal following among enthusiasts and racers, earning a reputation for its reliability, agility, and exhilarating riding experience.
