You can get beat by a Yamaha R6, Honda 600RR, etc. By next year, you can get a new or a use 848 for $................ What ever the new price is plus tax, tag, freight, doc prep. The dealer may give you a discount of $1,500 or so. A use one may be wiser, because you could save a lot of money due to depreciation, no sales tax, etc. These savings could add up to $4,000 to $5,000. Good luck.
