Rumors going around that Ducati is working on a MX bike that could be ready as soon as the 2024 season in MXGP and SX. A prototype engine is supposedly already on the test bench. In Supercross, there have been stories that Ducati is trying to go after Webb with a huge contract. If he moves to another team I would bet he goes to Yamaha to fill Tomac's spot before he jumps on an unproven new bike, regardless of the money.
