Wheels were now 17-inchers with a 160-60 rear. Minor changes came with the 1989 750K, the biggest being better ground clearance, while 1989’s sports production model – the 750RRK – was aimed at production racing with a long-stroke motor.1990 GSX-R750L1990 saw a return to the long-stroke motor as standard, but with the same high rev-ceiling (13,000rpm) of the J model. wheelbase and geometry changes while the front-end got the new ‘inverted’ or upside-down 41mm forks. section tyre.
