1985
The 1985 Kawasaki GPZ 1100 marked a significant year for Kawasaki's sportbike lineage. Building upon the success of its predecessors, this model aimed to capture the hearts of riders seeking a powerful and capable machine. During its time, it faced stiff competition from other manufacturers, going head-to-head with models like the Suzuki GS1150 in the high-performance motorcycle segment. The GPZ1100 aimed to provide a compelling alternative with its own distinct character and capabilities.
At the heart of the 1985 GPZ 1100 lies an air-cooled, inline-four engine with a displacement of 1089.0 ccm (66.45 cubic inches). This powerplant provided ample power for both spirited riding and comfortable touring. The fuel tank capacity is 20.00 litres (5.28 US gallons), allowing for decent range between fill-ups, a practical consideration for riders planning longer journeys. The engine's design and tuning prioritized a broad powerband, making it accessible and manageable in various riding situations.
The riding experience on the 1985 GPZ 1100 is characterized by a balance of sportiness and practicality. It provided a relatively upright riding position, which is less aggressive than track-focused ergonomics but more engaging than a laid-back cruiser. This allows for good visibility and control, contributing to rider confidence. While not a dedicated touring machine, the bike offered reasonable comfort for longer rides, especially considering its sporting intentions. The suspension setup was designed to provide a stable and controlled ride, absorbing bumps and imperfections in the road surface effectively.
The 1985 Kawasaki GPZ 1100 appealed to riders who appreciated a blend of performance and everyday usability. It was a motorcycle for those seeking a machine capable of quick acceleration and spirited riding, while still being comfortable and practical enough for daily commutes or weekend trips. If you wanted a powerful motorcycle that wasn't overly specialized, the GPZ 1100 delivered. Its combination of a potent engine and manageable handling made it a popular choice among experienced riders and those looking to step up to a larger displacement motorcycle.
