I miss my S4R. I sold it because I didn't have time to ride. Only after did I realize that Ducati stopped making monsters in a liquid cooled option. So much more power than the air cooled monsters. I felt like the handle bars were going to bend from all the torque when the throttle was opened up. I modified the air box, had the engined mapped, put on the fulll arrow exhaust and added aftermarket Ohlins suspension, revalved and resprung the front fork, plus a steering damper. What a great ride! I'm hoping that the SF is a quicker turning version of the same bike. I notice the 848 does not have the same amount of torque as the S4R though.
