Summary

When comparing the 2016 KTM 690 Duke and the 2016-2019 Kawasaki Z650, two powerful motorcycles with unique styles and target audiences, it is important to evaluate each bike's basic characteristics, pros and cons, and intended audience.

The KTM 690 Duke is a lightweight bike, designed for agility and speed, with the power of a powerful single-cylinder engine. It has a sporty and aggressive look, target at riders who want a motorcycle that can handle sharp, narrow turns and tight corners. Its frame and suspension systems are specifically designed to provide the rider with the ultimate balance of performance and control. The KTM 690 Duke is famous for its nimble handling and impressive stopping power.

On the other hand, the 2016-2019 Kawasaki Z650 is designed more for comfort and practicality, with a parallel-twin engine, lower seat height, and a more upright riding position. It is lightweight but not as agile as the KTM 690 Duke. Its appeal lies in its versatility, providing a comfortable ride on long journeys and practical for daily commutes. The Kawasaki Z650 is sleek, stylish, and affordable for riders who want a reliable bike for everyday use.

In terms of pros and cons, the KTM 690 Duke outperforms the Kawasaki Z650 in terms of agility and handling, but its high-center of gravity makes it harder to control at low speeds. Additionally, its single-cylinder engine can sound a bit rough compared to Kawasaki's twin-cylinder powerplant. On the other hand, the Kawasaki Z650 impresses with its comfortable ride, fuel efficiency, and versatile performance. However, some riders may find that its suspension system is not as refined as its competitors.

In conclusion, the KTM 690 Duke is a high-performance motorcycle that provides riders with unparalleled agility and control, making it an excellent choice for thrill-seekers who love to ride on winding roads. However, the Kawasaki Z650 appeals to a different audience who seeks a comfortable, practical, and versatile bike that can handle daily commutes and long rides. Each bike has its best points and areas of excellence while letting down in other departments, making it a tough choice to choose between the two.
