Ducati Streetfighter V4 S 2021 vs. Yamaha MT-09 2021

The Ducati Streetfighter V4 S 2021 and the Yamaha MT-09 2021 are both naked bikes that offer powerful performance and advanced rider assistance systems. However, there are several key differences between the two models.

In terms of engine power, the Ducati Streetfighter V4 S takes the lead with its V4 engine producing 208 HP, while the Yamaha MT-09 is equipped with an inline three-cylinder engine generating 119 HP. This gives the Ducati a significant advantage in terms of sheer power and acceleration.

The torque output also favors the Ducati, with 123 Nm compared to the Yamaha's 93 Nm. This means that the Ducati will offer more low-end grunt and better acceleration in lower gears.

Both bikes feature fuel injection systems and liquid cooling to ensure optimal performance and efficiency. However, the Ducati has a larger displacement at 1103 ccm compared to the Yamaha's 889 ccm, which again contributes to its higher power output.

In terms of suspension, both bikes feature upside-down telescopic forks at the front. The Ducati has a single swing arm and a monoshock at the rear, while the Yamaha has a swing arm with a monoshock. The Ducati's suspension is electronically adjustable Öhlins suspension, offering superior control and comfort.

The chassis of both bikes is made of aluminum, but the Ducati features a monocoque frame, which provides better rigidity and stability compared to the Yamaha's twin-tube frame.

When it comes to braking, both bikes have double disk brakes at the front. However, the Ducati has larger diameter disks at 330 mm, providing better stopping power.

In terms of advanced rider assistance systems, both bikes offer ABS and traction control. The Ducati goes a step further with additional features such as riding modes, dynamic suspension, cornering ABS, launch control, ride by wire, quickshifter, and anti-wheelie control. The Yamaha also has a quickshifter, but lacks some of the advanced features found on the Ducati.

In terms of dimensions and weights, the Ducati has a wider front tire at 120 mm compared to the Yamaha's 120 mm. The Ducati also has a larger wheelbase at 1488 mm compared to the Yamaha's 1430 mm. The seat height of the Ducati is slightly higher at 845 mm compared to the Yamaha's 825 mm. However, the Yamaha is lighter with a kerb weight of 189 kg compared to the Ducati's 199 kg.

Both bikes have fuel tank capacities of 14 liters for the Yamaha and 16 liters for the Ducati.

In terms of strengths, the Ducati Streetfighter V4 S offers the most powerful naked bike ever, with good ergonomics, superb electronically adjustable Öhlins suspension, brute Brembo Stylema brakes, a full electronics package, and a handsome, distinctive look. On the other hand, the Yamaha MT-09 offers a comfortable integrated seating position, a successful chassis, lively handling, and enormous riding pleasure.

As for weaknesses, the Ducati Streetfighter V4 S is very expensive, has a loud exhaust sound, and its full power is only available in the upper rev range. The Yamaha MT-09 has a polarizing look, a small TFT display, somewhat indirect front wheel feel, and cruise control is only available in the SP variant.

Overall, the Ducati Streetfighter V4 S 2021 is a high-performance naked bike with top-of-the-line features and a powerful engine, while the Yamaha MT-09 2021 offers a more affordable option with a comfortable riding position and enjoyable handling.
