Limited info on the published Ducati site, just says: “12,000 km (7,500 mi) / 12 months”
Would guess maintenance would be similar. But retail will be higher for the Ducati, and presumably well justified for the extra performance.
So, a guess again would be that they’ll probably coexist peacefully: Higher priced Ducati V4 with better performance, and a less expensive/less capable RSV4 at a lower price.
It literally says Desmo (Major) service is every 15k miles. Still not a japanese bike, but nowhere near as bad as that.
