The Suzuki GSX-R400 was first introduced in 1984 and remained in production until 1996. Designed as a lightweight sportbike, it was primarily aimed at the Japanese domestic market and was part of Suzuki's popular GSX-R series. The GSX-R400 drew attention for its compact chassis and high-revving engine, traits that made it an appealing option for performance enthusiasts in the 400cc category.
Despite its capabilities, the GSX-R400 was eventually discontinued due to a declining market demand for 400cc sportbikes, changes in licensing laws in Japan, and increased competition from larger displacement motorcycles. While the GSX-R400 is no longer in production, Suzuki continues to manufacture other models in the GSX-R family, including the GSX-R600, GSX-R750, and GSX-R1000, which remain globally popular, including in Pakistan.
Suzuki GSX-R400 Specifications
The Suzuki GSX-R400 featured a 16-valve DOHC transverse four-stroke inline-four engine with liquid cooling. The engine had a displacement of approximately 398 cc (24.3 cu in), offering a compact yet performance-oriented setup. Over its production years, there were slight changes in bore and stroke measurements, with the 1990-1996 models featuring 56.00 mm × 40.40 mm (2.2 in × 1.6 in). The compression ratio for these later models was 11.8:1, contributing to improved combustion efficiency and power delivery.
The bike produced a claimed power output of 60 horsepower (45 kW), while torque was rated at 28.3 lb·ft (38.4 N·m). The exhaust configuration varied across the years, including 4 into 2 and 4 into 1 systems. The GSX-R400 utilized a constant-mesh, sequential 6-speed gearbox and a chain final drive.
Top speed for the 1990-1996 version was claimed to be 127 mph (204 km/h), positioning it well among its class. The dry weight of the 1993-1996 model was approximately 167 kg (368 lb). As for its structural frame, Suzuki employed aluminium twin spar and aluminium double cradle designs during various model years, focusing on weight reduction and improved handling dynamics.
Suzuki GSX-R400 Design and Features
The design of the Suzuki GSX-R400 followed the aggressive styling language typical of sportbikes from the 1980s and 1990s. The bike featured a full fairing that provided aerodynamic efficiency and a sporty appearance.
The compact frame design, paired with clip-on handlebars and rear-set footpegs, supported an aggressive, race-inspired riding posture. Its dual headlamps and angular bodywork were key visual characteristics that aligned it with the larger GSX-R series. The bike's frame used aluminium components to ensure lightweight construction while maintaining strength, a common theme among performance motorcycles of the era.
Suzuki GSX-R400 Fuel Average
The real-world fuel average of the Suzuki GSX-R400 is 18 km/l, depending on riding style, engine condition, and maintenance. As a sportbike with a high-revving engine, its fuel economy is reasonable for its class but not the primary focus of the design.
Suzuki GSX-R400 Competitors
During its production years, the Suzuki GSX-R400 faced strong competition from several 400cc sportbikes. Chief among them were the Honda CBR400RR, Yamaha FZR400, and Kawasaki ZXR400. These bikes were also designed primarily for the Japanese domestic market and shared similar engine configurations, performance figures, and weight classes.
All these competitors contributed to a highly competitive segment that pushed manufacturers to deliver top-notch performance and technology in compact sportbike formats. In the Pakistani context, very few of these models were officially available, and like the GSX-R400, most were imported in limited quantities.
Is Suzuki GSX-R400 worth buying?
In 2025, the Suzuki GSX-R400 still holds appeal among motorcycle enthusiasts in Pakistan who appreciate classic sportbikes. It offers strong performance for a 400cc bike, and its lightweight chassis makes it fun to ride.
However, prospective buyers should consider the challenges, including limited parts availability, a shrinking number of qualified mechanics familiar with the model, and the aging nature of the machines. That said, for collectors or riders seeking a unique sportbike experience, the GSX-R400 can be a worthwhile second-hand purchase, especially if maintained well
