1983
The 1983 Kawasaki GPZ 1100 was a significant machine in the evolution of performance motorcycles. Following in the footsteps of the legendary Z1, the GPZ 1100 aimed to offer improved handling and a more refined riding experience. As a large displacement sportbike, it directly competed with machines like the Suzuki GS1100E and Honda CB1100F, all vying for supremacy in the early 80s superbike market.
At the heart of the GPZ 1100 was its potent 1089.0 ccm inline-four engine. This four-stroke powerplant was capable of producing a maximum power output of 120.0 HP at 9000 RPM. The engine also generated a substantial torque figure of 100.3 Nm at 7000 RPM, providing strong acceleration throughout the rev range. Weighing in at 244.0 kg, the GPZ 1100 carried 20.00 litres of fuel, allowing for decent range during longer rides. The combination of these specifications created a motorcycle with serious sporting credentials.
The 1983 GPZ 1100 provided a somewhat upright riding position, more comfortable than the track-focused ergonomics of later sportbikes. While not a dedicated touring machine, its suspension offered a reasonable balance between comfort and control, suitable for longer journeys. The bike's weight, however, could be felt during slower maneuvers, requiring a degree of rider skill. The engine's smooth power delivery made it manageable in most conditions.
The Kawasaki GPZ 1100 of 1983 appealed to experienced riders seeking a powerful and capable machine. It was a popular choice for those who wanted a blend of performance and practicality. While not the most nimble or comfortable motorcycle of its time, its powerful engine and distinctive styling made it a desirable option for riders wanting to experience the raw excitement of 80s superbike performance. It offered a distinctive alternative in a crowded market.
