It basically boils down to do you are willing too take the pros & cons of owning a brand new bike, with the advantages of full warranty and latest technology and features, ready for any customization & personalization mods a new owner "just does"...or take a lightly used 2 or 3 year old bike that may have some of those mods you were going to do and also take advantage of the still new technology like Brembo brakes, Stiffer Frame Redesign, slight increase in power/displacement, Anti-lock brakes, Security System and such that varied between the different model years previous. Take TQ's suggestion and base it with your specific current and future needs. Only you know when to pull the trigger, it is more about emotions and circumstances than just the numbers!
