I am afraid at present Kendo UI Gauge widget does not have a title option. Actually, this idea has been already shared at our UserVoice portal so if you wish you may cast a vote, leave a comment or monitor the community's interest in it here. The more votes the suggestion collects, the higher priority will have.

Meanwhile, as a possible workaround you can create a custom title and apply a custom styling to it in order to achieve the desired outcome.

Regards,

This is also not supported, however you could achieve it using the same approach as in my previous post:
