Type G (1986)

The bike was almost entirely redesigned for 86'. The power-to-weight ratio was increased to 0.39hp/kg with the new chassis and shorter wheelbase that Suzuki introduced. Both the 86' and 87' models use slightly different engines than before. The liquid cooling design that was used previously was dropped for Suzuki's "SATCS" (Suzuki advanced three-way cooling system) that used water air and oil to keep the engine cool. A new single square headlight was also introduced which was never very popular and Suzuki returned the headlights to the two circular lights the following year.

Type J (1988)

The GSX-R received a new stronger frame which increased the weight and new fairings with a lower wheelbase once again to create a more stable and better handling bike. The model also got slingshot carburetors, polished chrome silencers, curved radiator, Tokico 4-cylinder front brake calipers and a rear hugger mudguard. The new 4 into 2 exhaust was designed to create more midrange torque but this had only a marginal effect on the engines power.

A sports production model was introduced (SP) which incorporate among other things no passenger foot pegs and the rear shocks were visible under the seat.
