2026 Ducati Desmo450 MX – First Look

In typical Ducati fashion, the Desmo450 MX was developed with racing in mind, bringing in nine-time FIM Motocross World Champion Tony Cairoli and Alessandro Lupino to race pre-production bikes in the 2024 Italian Motocross Championship. Ducati found success quickly, even with standard suspension for the first few rounds instead of full race-spec componentry. Lupino went on to win the 2024 Italian MX1 Championship, and will seek to do the same while developing the Desmo250 MX in this year’s Italian MX2 series.

Ducati claims the engine produces 63.5 hp at 9,400 rpm and 39.5 lb-ft. at 7,500 rpm. More importantly, 70% of that torque is available at 4,200 rpm, thanks to the Desmo system which Ducati claims to use less effort to open the large diameter valves for more aggressive lift timing compared to traditional springs.

The cooling system uses two rhomboid-shaped radiators which Ducati claims to offer 6.5% more surface area than rectangular radiators, while still maintaining a compact package. Ducati also cited one round from the Italian MX1 championship that got interrupted due to extremely muddy conditions that forced many bikes to stop from overheating. Lupino and Cairoli’s bikes escaped unscathed.

For the chassis, Ducati designed an aluminum perimeter frame that uses just 11 separate elements, half the amount typically found on competing dirt bikes. Ducati says this reduces the number of welds, contributing to a claimed weight of 19.8 pounds, without compromising reliability or rigidity. The frame was important in helping Ducati keep the Desmo450 MX’s weight down to a claimed 231 pounds (without fuel).

The front of the frame which connects the steering column with the suspension is a single cast element using a process that allows precise control of its thickness, similar to the technology Ducati uses on its Superbike frames.

The braking system consists of Brembo calipers and Galfer discs. A two-piston floating caliper is matched with a 260mm disc up front, while the rear uses a single-piston caliper and 240mm disc.

The Desmo450 MX uses a unique four-level traction control system developed from Ducati’s experience in MotoGP and Superbike racing. The system adjusts the engine output based on actual rear wheel slippage using wheel sensors and can identify when to intervene and when it shouldn’t, such as during jumps. Riders can also temporarily deactivate traction control by applying light pressure on the clutch lever.

The electronics package also includes launch control, engine brake control, an upshift-only quickshifter, and two ride modes. Riders can customize the ride mode settings using the accessory X-Link app.

Maintenance intervals are 15 hours for oil and filter service, 45 hours for piston replacement and valve clearance checks, and 90 hours for main engine service. With motocross bikes being a completely new segment for the brand, Ducati says dealers had to go through an assessment and training process to ensure they will be able to provide the proper service. Unfortunately, that also implies that a lot of dealers may not be offering Ducati’s off-road models, so be sure to check with your local shop.
