I'd contact a local, recommended Ducati specialist and get a quote, I'd rather use a good specialist than a main dealer to be honest, I think you'll get a better service, better quality of work at a better price. Or, learn to do it yourself if you're confident with the spanners.
Agreed with the above, it's not a tough job, just tricky with the top belt, but once you've done it, you'll see it's an easy job.
Yep, it's not rocket science, valve adjustment is a little more complicated but, not the voodoo it's made out to be.
Belt prices probably vary between countries but I can tell you that I was charged two hours of labour if that helps.
Standard time on the 1260 is under a hour. The 1200 needed more parts removing, including the tank, for access and was about 2 hours iirc. If the standard times are followed, you’d be looking at around £200 inc the belts depending on the labour rates
That's taking the p*ss For £100 more I got the Desmo service, belts, all fluids (oil, brake and clutch), oil and air filters, new plugs and a good check-over from my local Ducati trained indi.
Tell them to go do one, that is a criminal quote! Which dealer? I'm sure others will want to avoid these clowns.
