Aprilia Tuono 660 2021 vs. Kawasaki Z650 2021

The Aprilia Tuono 660 2021 and the Kawasaki Z650 2021 are both naked bikes with similar engine configurations and displacement. However, there are several differences between the two models.

Starting with the engine, the Aprilia Tuono 660 2021 is equipped with an inline twin-cylinder engine that produces 95 HP of power and 67 Nm of torque. On the other hand, the Kawasaki Z650 2021 also features an inline twin-cylinder engine but with a lower power output of 68.2 HP and torque of 65.7 Nm. This gives the Tuono 660 a slight advantage in terms of power.

In terms of suspension, both bikes feature a telescopic front fork and a monoshock rear suspension. However, the Tuono 660 offers additional adjustment options for the rear suspension, including preload and recovery, which the Z650 lacks.

When it comes to the chassis, the Tuono 660 2021 features an aluminum frame, while the Z650 2021 has a steel frame. The aluminum frame of the Tuono 660 provides a lighter and more rigid structure, which contributes to its stability and precision in handling.

In terms of braking, both bikes have dual disc front brakes, but the Tuono 660 has larger 320 mm diameter discs compared to the Z650's 300 mm discs. The Tuono 660 also features four-piston radial calipers, which provide better braking performance compared to the Z650's dual-piston calipers.

In terms of electronic aids, both bikes come with ABS, but the Tuono 660 offers a more extensive range of advanced rider assistance systems, including riding modes, launch control, quick shifter, traction control, and anti-wheelie control. However, some of these features may come at an additional cost.

In terms of dimensions, the Tuono 660 has a slightly shorter wheelbase of 1370 mm compared to the Z650's 1410 mm. The Tuono 660 also has a higher seat height of 820 mm compared to the Z650's 790 mm. Additionally, the Tuono 660 weighs slightly less at 183 kg compared to the Z650's 187.1 kg.

In terms of equipment, both bikes come with LED headlights, but the Z650 also features LED daytime running lights and a TFT display with connectivity, which the Tuono 660 lacks.

In terms of strengths, the Tuono 660 offers an easy-to-use and sonorous engine, a sporty appearance, good ergonomics, decent brakes, extensive electronics (although at an additional cost), and a stable and precise chassis. On the other hand, the Z650 has the advantage of being an accessible twin-cylinder bike with compact dimensions, a low seat height, a stable chassis, and a mature appearance.

In terms of weaknesses, the Tuono 660 is criticized for its price-performance ratio and the additional cost of the IMU package. The Z650, on the other hand, may be uncomfortable for taller riders and may not provide the same level of adrenaline as its competitors.

Overall, the Aprilia Tuono 660 2021 and the Kawasaki Z650 2021 are both capable naked bikes with their own strengths and weaknesses. The Tuono 660 offers a more powerful engine, advanced electronics, and a sportier character, while the Z650 provides accessibility, comfort, and a mature design. The choice between the two ultimately depends on the rider's preferences and priorities.
