We have an '07 and a 2010 Speedmaster. Besides the tank difference (we like the '07 tank better), the EFI is a good choice. Bigger tank on the EFI models (19.5 litres). The torque curve is different between the carb and EFI models. Max torque on the EFI bike is at much lower RPM, and is more usable for me.
