Rare opportunity to acquire an original 1990 Suzuki GSXR750L UK spec with only 25,571 miles. This bike is in superb condition for the age of the bike, in fact we doubt you will find a cleaner bike. Although this model looks very similar to the previous '89 model many changes were made. The 90 model featured changes to the engine, suspension, body work, brakes and chassis. This was the first GSX-R to be fitted with inverted forks as standard, and returned to the bore and stroke of the original long-stroke engine. The engine returned to the 749 cc engine bore and stroke dimensions of the original long-stroke engine but still maintained the 13,000 rpm redline.
