Ducati is writing a new chapter in its history with the launch of the Desmo250 MX. One year on from the launch of the 450 MX – the first Ducati motocross bike of the modern era and the first in its class to feature a desmodromic system – the Borgo Panigale-based manufacturer is continuing to round out its off-road range.
Like all Ducatis, the Desmo250 MX has its roots in competition, where the Borgo Panigale-based manufacturer tests solutions that are subsequently made available to enthusiasts on production bikes. It was in fact developed on the track in the Italian Prestige MX2 championship by Alessandro Lupino and inherits the strengths of the Desmo450 MX: precision, control and reliability, all put to the test in the most fiercely contested segment of motocross, where the bike makes all the difference.
At the heart of the Desmo250 MX lies an engine that is new in every detail: compact, lightweight (24,7 kg) and powerful, delivering 44.5 CV at 12,500 rpm. It has been designed by drawing on the experience gained from the Panigale V4 R, the pinnacle of Ducati's technological expertise, with which the Desmo250 MX shares the same bore and stroke dimensions (81 x 48,4 mm) and some of the most advanced technical solutions. Fluid dynamics, duct geometries, valve timing profiles and flywheel masses have been developed to meet the specific demands of motocross: an engine designed to deliver power at every stage of riding. The focus was on achieving a sustained and balanced torque curve across all rev ranges, with a responsive low-end and a high-end power delivery capable of harnessing the benefits of the desmodromic system at all the decisive moments of the race: the start, corner exits and over-rev. Situations where every single tenth of a second makes the difference.
Desmodromic valve timing is Ducati's technological hallmark, and on the Desmo250 MX it reaches its full potential. Titanium intake valves, steel exhaust valves, and a level of control precision that allows the engine to be revved up to 15,000 rpm. A new benchmark for the category, enabling riders to hold each gear for longer.
The engine is powered by a 44mm Mikuni throttle body. The exhaust is completely new, designed to maximize performance and rideability while still complying with international competition noise regulations. Completing the package is a 5-speed gearbox developed specifically for the Desmo250 MX, equipped with a quickshifter in upshift, and a hydraulically operated Brembo clutch with a 7-plate clutch and a disc spring. A solution that ensures consistently precise and progressive acceleration, to cope with and adapt to the wear and tear typical of this discipline.
The result is an engine that allows anyone to express themselves to the fullest and adapt to different riding needs, without limiting the potential required by more experienced riders.
Handling is enhanced by the choice of original equipment Pirelli Scorpion MX32 tyres, which, in addition to providing high grip, ensure a rapid bike when changing direction and entering corners, thanks to the 100/90-19 rear tyre.
The braking system is shared with the 450: a Brembo system with 260 mm Galfer discs at the front and 240 mm at the rear. Uncompromising power and modulation, even for those riding a 250.
Benchmark Electronics
The Desmo250 MX is equipped with a superior electronics package, derived directly from the one developed for the Desmo450 MX, calibrated and optimized to enhance the characteristics of the 250. Two engine maps, customizable via the X-Link app, allow you to modify the level of throttle response. The Ducati Traction Control can be adjusted to three levels of intervention, the engine brake to two levels and the launch control to three. This allows every rider to tailor the bike to his or her riding style, terrain and racing conditions.
Traction Control, in particular, is the most advanced element of the electronics package. Thanks to its experience in MotoGP and Superbike, Ducati has created a true traction control system, which is the subject of a patent. This system increases rider safety and energy saving while riding, and can help to improve lap times. Unlike systems currently available in the segment, the Ducati Traction Control (DTC) implemented on the Desmo250 MX calibrates power reduction based on actual rear wheel spin, thus ensuring effective, prompt and linear intervention.
Predictive Maintenance
Thanks to its experience in Superbike and MotoGP, Ducati Corse has developed a specific algorithm that calculates an engine stress index in real time, based on operating parameters and conditions of use. The system then updates the maintenance schedules based on this information, which can be viewed via the Ducati X-Link app.
In this way, check and service schedules are adjusted based on usage, with more frequent interventions for professional/intensive riders or more spaced out for amateur riders, going beyond traditional static schedules.
Maintenance of the Desmo250 MX involves two types of service, known as “MID” and “FULL”.
The MID Service includes checking the valve clearance, which is carried out after 45 hours, and replacing the piston, which may be required at intervals ranging from 45 to 60 hours, depending on the calculated stress.
The FULL Service, which involves a complete engine overhaul, can generally be carried out between 90 and 120 hours, again depending on track conditions and the rider's riding style.
