1987
The 1987 Kawasaki GPZ 305 Belt Drive offered a unique proposition in the lightweight motorcycle market. While not as widely celebrated as some of its larger GPZ siblings, it aimed to provide an accessible and economical entry point into Kawasaki's sport-oriented lineup. This model year saw a refinement of the belt-drive system, aiming to reduce its inherent drawbacks. In a segment dominated by chain-driven machines, the GPZ 305 Belt Drive faced stiff competition from models like the Suzuki GS450, which offered similar performance characteristics with a more conventional drivetrain.
Powering the GPZ 305 Belt Drive is a 306.0 ccm (18.67 cubic inches) parallel-twin, four-stroke engine. This engine produces a maximum power output of 17.0 HP (12.4 kW) at 7500 RPM. The fuel tank capacity is 16.50 litres (4.36 US gallons), allowing for reasonable range between fill-ups. The bike's top speed is rated at 125.0 km/h (77.7 mph), positioning it as a capable commuter and weekend ride for riders who prioritize fuel efficiency and ease of use over outright speed.
The riding experience on the GPZ 305 is characterized by its light weight and manageable power. The upright riding position makes it comfortable for daily commuting and shorter trips. While not a track-focused machine, the GPZ 305 offers predictable handling and a smooth power delivery, making it a confidence-inspiring choice for newer riders. The belt drive contributes to a quieter ride compared to traditional chains, though some maintenance is still required.
The Kawasaki GPZ 305 Belt Drive was targeted towards budget-conscious riders and those new to motorcycling. Its relatively low power output and user-friendly handling make it an excellent learner bike. While it may not offer the same level of excitement as larger displacement sportbikes, the GPZ 305 provides a practical and economical way to experience the joy of riding. It represents a solid choice for riders seeking a reliable and easy-to-maintain motorcycle for everyday use.
