By the way, I think you'll like the new MV Agusta that will be in dealers in about two weeks. It's a 4 cylinder and very smooth power delivery (new fuel system), looks good, exotic, runs cooler (new cooling system), LED running lights, but priced lower than the Ducati.
Pro Italia's the only dealer in the L.A. area but they do offer test rides and will take your 1198S on trade because they're also a Ducati and Aprilia dealer. So, I think you should go there and give it a try!
Buy it!! Buy it!!! Buy it!!!!

And these guys will let you take a demo ride before you buy. I don't receive anything if you buy from them. I just like their shop and if you're going to buy a new bike and sell/trade/or consign (which they may do) for a new bike, you may as well give the business to these guys. Oh, and they carry Aprilia and you can demo ride the RSV4 also.
