The Most Powerful Single-Cylinder in the World: Superquadro Mono by Ducati
It's poised to set new standards in the world of single-cylinder engines and redefine the way we experience motorcycles.
When it comes to exceptional engineering, breathtaking performance, and cutting-edge motorcycle technology, Ducati has always been at the forefront. Their latest addition to the Ducati engines lineup, the Superquadro Mono, is nothing short of a marvel. In this comprehensive article, we will explore every aspect of this powerhouse, from its impressive features to its mind-boggling performance capabilities. So, gear up, and let's dive into the world of the most powerful single-cylinder engine in the world.
A Brief Introduction
The Superquadro Mono is a brand-new 659 cc short-stroke single-cylinder engine with desmodromic distribution. This engine is not just a step forward; it's a leap into the future of motorcycle engineering. With high revs and top performance, the Superquadro Mono is destined to set new standards in the world of single-cylinder engines.
Inheriting Racing DNA
Derived from the 1,285 cc Superquadro of the 1299 Panigale, the Superquadro Mono inherits the racing character of its predecessor and incorporates the innovative desmodromic system. This system allows it to rev higher and deliver truly exhilarating bursts of acceleration. The limiter is set at an astonishing 10,250 rpm, a speed that no other single-cylinder engine can match.
With a power output of 77.5 hp at 9,750 rpm (which can increase to 84.5 hp with the racing exhaust), the Superquadro Mono boasts the highest power output in its segment. What's more, it offers benchmark maintenance intervals, with an oil change required only every 15,000 km and a valve clearance check every 30,000 km. This means less time in the workshop and more time on the road.
For A2 License Holders
In addition to the high-performance version, Ducati has also made the Superquadro Mono available in a depowered version tailored for A2 license holders. This thoughtful inclusion means that even riders with restricted licenses can experience the thrill of the Superquadro Mono.
The Superquadro Design Philosophy
The name "Superquadro" is not just a fancy moniker. It reflects the extreme bore and stroke ratio that allows for high rotation speeds. This name has been proudly worn by the engines of Ducati's twin-cylinder Superbikes, and the Superquadro Mono is no exception. It inherits the thermal part, which includes the heart of the engine, the piston, the combustion chamber's design, and the desmodromic system.
116 mm Racing Piston
The piston of the Superquadro Mono is a racing-type piston with a diameter of 116 mm. This impressive bore sets a new record for a production single-cylinder engine. Coupled with an ultra-short stroke of 62.4 mm, it achieves an extraordinary bore-to-stroke ratio of 1.86. This exceptional ratio allows the engine to reach high rotation speeds, providing an endless source of fun.
The piston is designed as a "box in box" with double ribs, maximizing strength and stiffness while minimizing friction. This design ensures that the engine runs smoothly, generating a thrilling riding experience.
Titanium Intake Valves
The Superquadro Mono also adopts large 46.8 mm diameter titanium intake valves, which significantly reduce mass and inertia. Furthermore, the engine features 38.2 mm steel exhaust valves, borrowed from the twin-cylinder Superbike engine. The desmodromic system is, of course, a part of the package.
The Power of Desmo
The combination of the Superquadro Mono's large valve diameters and high rpm levels introduces significant inertial stresses. To overcome these challenges, the intake valves are made of titanium, and their management is entrusted to the Desmodromic system. This mechanical system allows the engine to push the limits imposed by valve springs, enabling extreme valve lift laws with large diameter valves at high engine speeds. The effectiveness of this system is such that it's even used on Ducati's MotoGP bikes.
659 cc of Sophistication
Ducati's commitment to excellence extends to the choice of materials for each component of the engine. For instance, the cylinder barrel is made of aluminum rather than steel, drawing inspiration from the 1299 Superleggera. The alternator, clutch, and head covers are crafted from a lightweight and durable magnesium alloy. These choices not only reduce weight but also contribute to the engine's overall performance.
Low Vibrations and Panigale Gear Ratios
One of the key attributes of the Superquadro Mono is its ability to limit vibrations. The engine achieves this by using two balancing countershafts positioned in the engine crankcase. These counteract the forces generated during operation, resulting in vibrations comparable to those of a 90° V-twin engine.
The gear ratios of the Superquadro Mono are modeled after those of the Panigale V4. This includes a long first gear designed for navigating corners at low speeds, allowing riders to make the most of the engine's power when exiting turns.
Redefining the Game
The Superquadro Mono is more than just a powerful engine; it's about to become the beating heart of a new Ducati motorcycle. This new bike promises to be an unprecedented mix of fun and performance, raising the bar for emotions both on the track and on the road. It's an essential, light, and nimble motorbike—a true "fun-bike" with racing DNA.
