Ahad, I happen to own a 1999 Ducati SuperSport 900.
I can safely tell you that I am 100% happy that i DID NOT start on this bike for a first bike. I started on a Ninja 250.
They have a rather difficult clutch to learn with. It's a dryclutch setup and is a lot more direct than a normal clutch. If you started with this you'd have a hell of a time learning for sure.
To top this off if it is your first bike you're going to find things uncomfortable, strange and foreign to you as you learn. Commonly riders do drop their first bike (i'll even admit, i dropped my first bike once at a stoplight..) and the fairings and parts for the Ducati are very expensive. Just to give you an idea, the bolt for my sidestand was $32.. pretty silly. Valve adjustments will run you about $400-600 at the dealer every 6000 miles if you don't do them yourself, add in changing your timing belts every 2 years, new tires every 4000 in the back and 8000 miles in the front at $200 a pop for pilot powers and then the cost of around $50-80 an oil change (that's for really good oil, the filter, the washer, and doing it YOURSELF) and even more if you bring it to a dealer.
They are very expensive bikes to maintain and not at all a good choice for a first bike simply not only because of the power, pain in the butt attitude of riding around town with them, but also the price of repairing ANYTHING on them if you drop them. Imagine dropping your Ducati at a stoplight and having the unfortunate happening of denting your tank and it gets a hole in it. A brand new tank from Ducati for the supersport 900 is $1200. Seem like a lot? Yeah, it is.
On the flip side to this.... I'm going to bring it back to a positive light.... they are not a bike you see every day, pretty rare. A lot of fun, very rewarding, and an experience you'll never forget. They feel like a bottomless pit of torque and are a fabulous bike to own, period. I simply wouldn't recommend it for a first bike.
On that note... as i said i started on a ninja 250. They are affordable, easy to maintain (and cheap), a valve adjust for a 250 is around $120. The tires you can get around $150 (for BOTH, altogether), the fairings and repairs are far less costly should you drop it, and they are light and very forgiving little bikes to learn on. You'll learn throttle control properly as you don't have a desmodue with over 90hp at your fingertips, and a lightweight bike that is easy to manipulate and ride around. They get 60-70mpg (you can't hate that) will still do around 105-110mph if you REALLY want them to, are cheap to insure and have a really really good resale value on them when you buy used.
The oil change is about as cheap as my escort (about $25 each time) and they require very little maintenance except having the carbs cleaned now and then. Overall i'd start with something like a 250, you'll love it in the long run.
Start with something less complex, less costly and more forgiving for your first bike. Make the Ducati YOUR GOAL. Ride a bike that is easy to learn on with the mindset "If i learn to ride this well, i will earn myself the self taught knowledge and confidence to ride the bike I REALLY want without worry." and make it happen.
Be safe out there, feel free to email me or message me with any motorcycle questions, I'm an absolute riding NUT

I'd also be happy to answer any ducati questions you have, I do all the maintenance on mine myself.
