It is really easy to steal a bike, especially in a big city and if the place is not gated or have ceilings (allowing big Uhauls to come in and hoist the bike in).
There are MANY ways to steal bikes, I am sure. And a Ducati is a prime product for it as they are light and of high value. Yes, the magnetic key lock is a great deterrent as it makes it hard to sell, but still easy to sell parts from.
I have a few techniques, as I have two places I keep my bike over night.
A.) Work location - 3 story subterranene garage that is "Gated" but nothing more than a wooden arm machine.
This location I employ the following outside of the normal handlebar lock, set in 1st gear.
1.) I use this lock on the rear tire: http://www.motorcycle-superstore.com...Disc-Lock.aspx
(The problem is that it does not lock to anything, as I have nothing to tie it near.
2.) I place the bike RIGHT under a security camera. Though the camera is not always watched, it is there to freak people out that they are likely being watched. It may also help that I have the footage in case it is stolen.
3.) I use a motorcycle cover that snuggly fits over the bike. It doesnt say DUCATI on it, just a black fitted tarp that keeps the dust off and keeps people from looking at the bike.
4.) The bike is placed parallel with a parking block so that it is hard to throw sticks in the wheels and hoist up. It is also blocked by a small staircase - further making theives life difficult.
B.) Then, there is my apartment building. It is gated, which is nice - but as big as the complex is, people could still access the clickers- or simply wait for someone to open one of the entrances- as people are too passive aggressive to try and stop anyone if they are even suspected as a theif. The bike is covered here, but is also half exposed to outside elements (some sunlight).
1.) I typically do not lock the bike up as I place the bike in such a difficult place to steal and this is what I suggest you do as you have a car! I pull my car our, then pull my bike in front of the car parking spot. So its as if you would see city parked bikes that squeeze infront of cars in parallel parked spots. My bike is infront of a parking curb, parallel with the cement parking curb. Then I drive the car in - and boom- its blocked.
The cars parked to my left and right are typically there in the night to help block anyone that might be able to unlock the bars and set to neutral and snuggle it out. So, its pretty worry free. Also, I cover it with a HUGE tarp (lets a lot of airflow) but also does not suspect the bike as a small little Ducati, but rather a huge ass Harley since theres sooooo much space. I dont bother locking the rear tire as the bike is barricaded by a cement wall, a cement block (to deter steering and hoisting) and blocked by all sides due to my car and my neighbors parked cars and poles (Its a covered spot)
Sorry that post was long, but I wanted to detail all the aspects of how I keep my bike safe as I always worry about it being that I am in a big city (LA) and ride a light bike (2005 620 Monster).
I suggest you do the car trick, as it makes it so hard to steal - that is, if your bike is blocked by other cars or a walls/poles in your parking lot. Another thing you can do is throw a long cable or chain from your rear wheel through your car tire. I have done that when I leave for vacation. It lets me sleep well at night.
Also, make friends with your neighbors and let them know you got their back on the vehicles. Me and another guy who keeps his S2000 in the work garage make sure to check on one anothers vehicles.
Oh, and another deterrent is myself - if I see someone trying to steal my bike - it gives me the invitation to throw some jitsu on 'em. But of course, thats a last resort, and is only helpful if I am around.
