They're $875, and there are 4 left right now. I had 5 full days of riding my SV with the new superbike motor and slipper clutch, alternating with riding my Ducati 749R. Honestly, the slipper in the SV worked identically to the slipper in my Duc. Heading into Turn 5 at Grattan (clockwise direction), you go over a steep crested hill (the "Jump Ramp") right before entering the corner and then throw it into the right-hander scrubbing off speed as you enter the turn (if you have the guts to not brake before the hill). I was able to downshift with the rear wheel in the air as I crested the hill and allow the slipper to handle keeping the rear end sorted as I entered the turn. That was too cool to accurately describe! I could do the same thing on my Duc. With a stock clutch, I would have had to be very careful with the lever to feather it out and not lock up the rear wheel and highside myself into the weeds. I've kicked the blipping habit, slippers are my best friend now!
