30 YEARS OF SUZUKI GSX-R750
P58
GSX-R750 L
The 1990 model year
saw a raft of changes to the
GSX-R750, most notably the
introduction of fully adjustable,
inverted forks. The U.S. would
have to wait until 1991 before
they'd be getting inverted, but
they got the rest of the changes.
These included a return to
the long-stroke design—now
pumping out 115 horsepower—of
the original 750, Mikuni 38mm
carbs that were 2mm larger
than the 1989 models but 2mm
smaller than the RR's, new
conrods, lighter pistons, large
capacity oil pump and reshaped
oil cooler, new 4-1 exhaust and
a revised gearbox.
On the chassis side,
wheelbase grew 10mm
to 1410mm (55.5 inches),
there was a new shock and
swingarm, wider rear wheel,
new non-adjustable steering
damper (but not for the U.S.
market, we only got the
mounting holes drilled in the
frame).
If Americans felt ripped off
by the fact they had to wait a
year for the new inverted forks
to arrive in the country, it got
worse for 1991. This is where
the GSX-R started to lose the
plot, gaining 33 pounds over
the 1990 model thanks to a
new fairing, lights, seat and rear
bodywork.
New forks and a new
motor kept Suzuki on
the game in 1990
