I've owned my Triumph Daytona for about a year now and nothing but good has come from her, she's fast nimble and waste cops!
Downfall: she seems to under steer slightly through the turns and getting her into them is a handful at times. I only weigh 160 so bigger riders could learn to love her.
Plus: power kicks in a little too high in the rpm range but when she does kick in, the Bat Mobile comes to mind. Nice bike to wheelie with to, and if your like me I'd rather not have the same bike at the stoplight as the guy right next to me.
