To save more weight, the suspension was engineered differently from most bikes of the day by mounting the top of the shock solidly to the frame while the bottom was attached to a banana shaped linkage that housed an eccentric cam below the swing arm. The resulting system was light weight, made suspension travel progressive and lowered the bike’s overall center of gravity.While the engine used was a dual overhead cam, four valves per cylinder design typical of most bikes of the era it had unique features that set it apart from other air cooled designs of the day. In the GSXR, oil would be used to cool parts of the engine, like the top of the combustion chamber, which were not typically well served by air cooling alone. In order to provide enough oil for both cooling and lubrication, the team designed a double chamber pump, using the high pressure side to lubricate the bearings and while the low pressure, high volume side provided oil to the cooling circuit. The end result became known as the SACSSuzuki Advanced Cooling System. The resulting motorcycle was rigorously tested to its breaking point, the weaknesses found and re-engineered until the bugs were worked out.
