🔍 Model Background

The Suzuki GSX 400 (1981–1999) was a mid-sized standard motorcycle developed to deliver everyday practicality, responsive performance, and mechanical simplicity. Positioned between entry-level 250s and larger 750-class machines, the GSX 400 earned its place in Suzuki’s lineup as a reliable all-rounder for commuters and weekend riders alike.

Early models like the GSX 400F and FZ featured a 398cc air/oil-cooled DOHC parallel-twin engine, known for its rev-happy nature and smooth powerband. It was mated to a 6-speed transmission and used Suzuki’s SACS (Suzuki Advanced Cooling System) for improved heat dissipation. Over the years, the platform saw multiple updates in styling, frame design, and componentry.

The GSX 400 was appreciated for its light handling, low seat height, and dependable road manners. Variants like the GSX 400 FD and FZ added sportier design cues, while keeping the bike affordable and approachable. Though it didn’t aim for top-tier performance, it delivered a balanced, efficient, and rider-friendly experience that stood the test of time.

Produced for nearly two decades and popular in both domestic and export markets, the GSX 400 is still sought after by enthusiasts who appreciate vintage Suzuki engineering, minimalist design, and ease of maintenance.
