The Superquadro Mono is based on the Panigale 1299 engine, the 1285 cc Superquadro, which represents the evolution of Ducati's street-legal twin-cylinder. The Superquadro Mono inherits from the Panigale the 116 mm diameter piston, the shape of the combustion chamber, the 46.8 mm diameter titanium intake valves, the 38.2 mm diameter steel exhaust valves and the Desmodromic system.
The name Superquadro comes from the extreme ratio between bore and stroke which allows, thanks to the very short stroke, to reach rotation speeds typical of racing engines. On the Superquadro Mono this ratio is equal to 1.86 and is the most extreme in the category thanks to a stroke of just 62.4 mm.
The 116 mm bore allows the use of large diameter valves to improve performance, which would not be possible without the Desmodromic system. This system, which Ducati also uses on its MotoGP bikes, makes it possible to overcome the limits imposed by the valve springs, allowing extreme valve lift laws. In this way, the Desmodromic system contributes significantly both to performance and to the possibility of reaching very high rotation speeds.
Thanks to these solutions, the Superquadro Mono delivers a maximum power of 77.5 hp at 9,750 rpm and is capable of reaching 10,250 rpm, values never before achieved by a single-cylinder. Maximum torque is 6.4 kgm (62.7 Nm / 46.3 lb-ft) at 8,000 rpm. In racing configuration with Termignoni exhaust, this single-cylinder is able to reach the maximum power value of 85 hp at 9,500 rpm.
The Superquadro Mono will also be used on motorcycles for A2 licence holders in a detuned version.

The transmission relies on a six-speed gearbox with racing ratios derived from the experience gained with the Panigale V4. The first gear is in fact long to allow its use in slow corners, exploiting the maximum thrust available. The clutch is in an oil bath with progressive interlocking hydraulic control, characterized by a particularly reduced lever load and specifically developed to offer easy and intuitive braking behaviour, with maximum modulability on release and in engine brake management to facilitate power-sliding in corner entry.
The gearbox can be equipped with Ducati Quick Shift (DQS) Up & Down. In this application, the DQS relies on a magnetic hall effect sensor and not the traditional load cell to improve accuracy and reliability.
The Superquadro Mono will equip the bike that will star in the fifth episode of the Ducati World Première 2024 "Live. Play. Ride", on Thursday 2nd November at 4.00 pm CET on Ducati.com and on Ducati's YouTube channel.
