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 types, fuel systems, and cooling systems. However, there are several key differences between the two models.

In terms of engine power, the Aprilia Tuono 660 has a higher output with 95 HP compared to the Kawasaki Z650's 68.2 HP. The Tuono 660 also has a higher torque of 67 Nm compared to the Z650's 65.7 Nm. This gives the Tuono 660 a more powerful and responsive performance on the road.

Both bikes have a two-cylinder engine configuration and a liquid cooling system. The Tuono 660 has a displacement of 659 ccm, while the Z650 has a displacement of 649 ccm. This slight difference in displacement may result in a slightly different riding experience, with the Tuono 660 potentially offering more power and acceleration.

In terms of suspension, both bikes have a swing arm rear suspension with a monoshock absorber. However, the Tuono 660 features an upside-down telescopic fork front suspension, while the Z650 has a regular telescopic fork front suspension. The upside-down fork on the Tuono 660 may provide better stability and handling during aggressive riding.

The chassis of the Tuono 660 is made of aluminum and has a load-bearing engine design, while the Z650 has a steel frame with a tubular design. The aluminum frame of the Tuono 660 is lighter and may contribute to better overall handling and maneuverability.

Both bikes have double disk front brakes, but the Tuono 660 has larger 320 mm diameter disks compared to the Z650's 300 mm diameter disks. The Tuono 660 also has four-piston front brake calipers and radial technology, which may result in better braking performance and control.

In terms of advanced rider assistance systems, the Tuono 660 offers a more extensive range of features. It includes ABS, riding modes, launch control, ride by wire, a quickshifter, traction control, and anti-wheelie. On the other hand, the Z650 only has ABS as its advanced rider assistance system.

In terms of dimensions and weights, the Tuono 660 has a slightly shorter wheelbase of 1370 mm compared to the Z650's 1410 mm. The seat height of the Tuono 660 is also slightly higher at 820 mm compared to the Z650's 790 mm. The Tuono 660 has a kerb weight of 183 kg, while the Z650 weighs slightly more at 187.1 kg.

In terms of strengths, the Tuono 660 offers an easy-to-operate engine with a good sound, sporty handling, good ergonomics, decent brakes, and extensive electronics. The Kawasaki Z650, on the other hand, has an accessible two-cylinder engine, compact dimensions, a low seat height, stable chassis, and a grown-up look.

However, the Tuono 660 has a higher price and the IMU package, which includes some of the advanced rider assistance systems, costs extra. The Z650 may also be less comfortable for tall riders and may not provide the same level of adrenaline as some of its competitors.

In conclusion, while both the Aprilia Tuono 660 2021 and the Kawasaki Z650 2021 are capable naked bikes, the Tuono 660 offers more power, advanced rider assistance systems, and a higher level of performance. However, it comes at a higher price point. The Z650, on the other hand, provides a more accessible and comfortable riding experience with a more affordable price tag.
