Suzuki also changed the GSXRs frame type multiple times - with different twin-spar and double-cradle arrangements sampled throughout the production run - though they were always constructed solely of aluminium.

In 1988 the GSX-R received a new aluminium 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 stainless steel silencers, curved radiator, Tokico 4-cylinder front brake calipers and a rear hugger mudguard.

In 1988 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.

In 1990, Suzuki introduced a completely new model GSX-R400 with inverted forks and new double cradle aluminum frame and with a new 4 into 1 exhaust power increased to 60 hp (45 kW).
