I would have thought that going down in size on the front may speed up the steering too much for that style of bike unless you alter the tyre size to compensate and then you're back to the rolling diameter of the standard set-up.

If you just want to lower the seat height there are a couple of more conventional ways of going about it.

Firstly, buy the low seat that is available from Ducati, easily changed and designed to fit:

Or go a slightly different route and fit a lowering kit like this:

Remember though that the lowering kit will only lower the rear suspension and you may (or may not) need to pull the forks through the yokes to compensate and keep the geometry at the factory setting- this will of course lower the bike overall and reduce ground clearance as a result.

Personally, if you want the seat lower then buy the low seat option.
