My brother has Ducati, so I guess that it's the best bike I've ever seen. It's so fast and furious that I 'm afraid of it and powerful noise!
it depends if its a desmosedici i would choose ducati. If its a fight between the 1198 and rsv4 i think id try the rsv4 only because I rode the 1198 and it wasn't as comfortable as I hoped for.
Both of manufacturers are working real hard, both represents a lot of new motors and honestly I just can't decide which one I do like more - rsv4 or 848.
