Compared to other bikes of the time, the GSX-R400 was very light and the 4-piston brakes at the front and the 2-piston rear brake was more than adequate for the 152 kg (334 lbs) light street racer. The bike was quick to handle, the engine with 4-1 exhaust system was powerful for its size and made the GSX-R the fastest bike in its class. With the maximum power output 59 hp and 152 kg (334 lbs( dry mass, the power/weight ratio (2,57 kg/hp) was even better than Suzuki’s incredible 2-stroke racer, RG250 Gamma. The GSX-R400 started a new era, it was the fastest and best-handling 400cc bike ever made.
The water-cooled inline-four four-stroke had double overhead camshafts and four valves per cylinder. The GSX400FW (presented the previous year) had the same principal engine specs but lower power output and the GSX-R400’s new engine with its 66 kg (145 lbs) was 10 kg (22 lbs) lighter. 12,000 maximum revs. This bike was a real street fighter.
