Thank you for such a detailed response. I really appreciate it.
Guess we will see when we get to the track 😈
2) the function is related to load, rather than RPM directly:
Back torque is greatest in the lowest gears, same as 'forward '. Chop the throttle at high speed in second, drop a gear and pop the clutch without revving the motor and the engine compression will refuse the change in shaft speed much more than in higher gears. Skidding, squirming, wheel hop can occur.
The slipper function is initiated by that force, and consists of a simple set of ball bearings in ramped grooves. The rear wheel 'backwards' load twists the plate one side of the groove is cut into. That twist is translated into a jacking motion, that levers the pressure plate away from stack of pressure and friction plates. 'slip' is induced. Purely analog anti-lock technology, and very subtle in operation. Spring tension alone dictates how much force initiates the function.
Because the wheelbase is so short, and how easy that makes it to do a stoppie on these things, the impact of having or not having a slipper function is limited in street use.
Stuffing the bike into a corner at max lean while trying to maximize pending drive out of that same corner may require a ham fisted down shift while making use of that last inch of rubber on the shoulder of the tires. Electronic quick shifters that work on a down shift exacerbate the impact......[/QUOTE]
