Ducati have decided that Desmo Owners Club members will now update their own information, this is great news for those of us running the clubs as it means less work for us, although I imagine it has more to do with GDPR compliance.
If you're not already registered, go to ducati.com and click on the myducati link in the top right corner

Choose 'Sign Up', or Login if you've already signed up

Fill in the form with your first & last names, your email address (the same one you use for UKMOC affiliation),
I strongly recommend you allow marketing activity, as not checking this box means you will NOT receive things like WDW discount codes!

and click on the red 'REGISTER' button, you now need to check your email and complete the process by clicking or pasting the link you have been sent.

Now you can Login to myducati using your email address and the password you created in the last step.
You can now fill in or update the rest of your 'PROFILE'
There's a 'nickname' space at bottom right, where you can put your UKMOC username (or 'UKMOC username'+1 if you're applying for your partner). This may make it easier for us to identify you.

Click on the 'PRIVACY' button to select your preferences (remember to allow marketing, as before, for offers etc.)

from the menu button

you can update info about your bikes (MY GARAGE), if less than 10 years old

and also apply to join DOCs, including UKMOC. (MY CLUB)
