The '''[[Suzuki]] GSX-R400''' was a Liquid Cooled, Four Strike, Transverse Four Cylinder, DOHC 4 Valves Per Cylinder Sport Bike [[motorcycle]] produced by [[Suzuki]] between 1989 and 1993. Max [[torque]] was 28.77 ft/lbs (39.0 Nm) @ 10000 RPM. Claimed [[horsepower]] was 52.97 HP (39.5 KW) @ 12000 RPM. 
== Overview ==
The '''GSX-R400''' (initially called '''GSX-R''' in Japan, internal model code GK71B) was
released in March 1984. It was the first mass-produced light-weight racer
replica with an aluminum cradle frame and a liquid-cooled inline-four DOHC
engine with four valves per cylinder. The, in those days, amazing machine
was based on Yoshimura's TT-F3 racer [[Suzuki GS1000R|GS1000R]]. The competitors, [[Yamaha FZ400R]] and [[Honda CBR400R]] were 13—31 kg (29—68 lbs) heavier than the new and quick GSX-R.
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, [[Suzuki RG250|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.

When 400 cc ruled the world of motorcycles, Suzuki’s GSX-R400 was the rarest little dinosaur. The Suzuki GSX-R400 feels very similar to its larger brother, but shrunk down. Its tiny pegs are high and are a nightmare on the road but they make sense on the track. However, you need to play around with the suspension.
