Ducati’s single-cylinder, 659cc engine promises to redefine its category with power figures such as 77.5 HP at 9,750 RPM and a peak torque of 62.7 Nm at 8,000 RPM. Ducati also plans a detuned version for A2 license holders to widen the engine’s reach.
Ducati, the renowned guys and girls over in Bologna, is setting the stage for a remarkable comeback in the world of high-performance bikes. At the heart of this revival is the Superquadro Mono engine, a single-cylinder powerhouse that’s rekindling memories of the iconic Supermono 550 from over three decades ago.
This engine, boasting a displacement of 659cc, is equipped with Ducati’s Desmodromic system, as is the fashion with the Italians. While its modest size might not suggest it, the Superquadro Mono is about to redefine what’s possible in its category.
Ducati’s engineering team took inspiration from the formidable Panigale 1299 engine for the Superquadro Mono. They’ve adopted key elements, including the 116mm diameter piston, combustion chamber design, 46.8mm diameter titanium intake valves, 38.2mm steel exhaust valves, and the legendary Desmodromic system. Yet, it’s the extraordinary bore-to-stroke ratio of 1.86, with a stroke measuring just 62.4mm, that sets this engine apart.
It’s a record-breaking ratio that allows the Superquadro Mono to achieve rotation speeds typically associated with racing engines. The result? A staggering 77.5 horsepower at 9,750 rpm and a peak torque of 62.7 Nm at 8,000 rpm, all while meeting the stringent Euro 5 homologation standards. If you crave even more power, the racing configuration, equipped with a Termignoni exhaust, pushes the limits to a rather fetching 84.5 horsepower at 9,500 rpm.
But here’s where it gets even more interesting – Ducati isn’t content with this power plant being confined to their top-tier bikes. They’ve thoughtfully designed a detuned version for A2 license holders, ensuring a broader audience can experience the thrill of this incredible engine.
Ducati’s engineering team has chosen the finest materials and solutions for every component. The 116 mm bore piston, derived from racing heritage, features a “box in box” layout for enhanced rigidity and reduced friction, not unlike the pistons found in the Panigale V4 R.
Ducati’s commitment to innovation extends to the internal components of the engine as well. The rocker arms of the Desmo system feature a Diamond Like Carbon (DLC) surface coating, significantly reducing friction and increasing resistance to fatigue. The distribution is expertly managed through a mixed “silent” gear/chain system.
Fuel feed is entrusted to a single oval-section throttle body with a 62mm equivalent diameter. An under-throttle injector, controlled by a ride-by-wire system with three different Power Modes (High, Medium, Low), adapts the engine’s delivery to different riding situations.
The Superquadro Mono also incorporates a semi-dry sump lubrication system, an integrated water jacket, lightweight aluminium crankcases, and various lightweight components to reduce weight while ensuring mechanical robustness. The crankshaft, an asymmetrical masterpiece, balances the engine’s weight distribution. Two balancing countershafts, one front and one rear, effectively manage engine balance while maintaining vibration levels comparable to a 90° V-twin engine.
As if that’s not impressive enough, the ‘Mono features two lobe pumps – a delivery pump for efficient engine lubrication and a recovery pump to minimise friction losses. The design brings the crankshaft compartment under a vacuum, reducing resistance of moving parts and ensuring effective oil recovery regardless of usage conditions.
The gearbox, a six-speed unit with ‘racing-inspired’ ratios, guarantees optimal thrust in slow corners and maximises performance. The oil-bath clutch offers progressive interlocking hydraulic control, providing reduced lever load for intuitive braking behaviour, with maximum modulability upon release.
The Superquadro Mono can be equipped with Ducati Quick Shift (DQS) Up & Down, with the DQS relying on a magnetic hall effect sensor for improved accuracy and reliability.
The grand reveal for Ducati’s single cylinder, the Superquadro Mono is scheduled for the fifth episode of the Ducati World Première 2024 event on November 2nd at 1700 GMT.
