The GSX-R400 was originally launched in Japan in 1984 with the GK71 model, featuring a liquid-cooled inline four cylinder engine with DOHC, four valves per cylinder and close to 60 hp.
Lighter than its rivals (under 350 lbs wet), the aluminum framed Suzuki became a hit with its excellent handling, more-than-adequate brakes, and a race-derived heritage.
This example is VIN: GK73A10417. The seller acquired it from Iconic (the bike had been imported from the UK) through an auction in August 2024.
The odometer shows 53,564 kilometers (33,283 miles). The odometer was removed in April of 2025 and the bike was setup for track days. The bike has seen 6 track days total. The bike has since been put back to road going condition. “I just really wanted a novice friendly track bike with a vintage style. It surpassed my expectations and I managed to get my race license and run 2 ARHMA races in 2025/2026. I’m only selling because of travel plans, otherwise I’d keep it forever!”
