Overview[edit | edit source]
Suzuki GSX-R 400
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 GS1000R. The competitors, Yamaha FZ400R
and Honda CBR400R were 1331 kg (2968 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, 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.{| class="wikitable"
