Had I known that there was a "Sure Shift" option when I purchased my TKO600, I'd probably have opted for it, since I think I opted for nearly everything else including the kitchen sink.
Now if I could find a nice set of magnesium wheels and an electronic EFI that works flawlessly the "first time" and "every time" and is literally plug and play, then I could check off those two options.
The SOHC being the last and final option.
