Slipper pistons

So I have my own little definition of what a slipper piston is, but it's probably wrong. :whistle:

Can someone correct me as to the right definition of a slipper piston?

Slipper piston
A Piston with the lower edge cut away so that the Piston skirt is short on the two sides not used as thrust surfaces. Such a design lightens the piston making it easier to accelerate and decelerate, wastes less power, and is easier on the bearings. Cutting away the skirt also allows the Connecting rod to be made shorter but leaves enough room between the Counterweights and the pistons so the overall height of the engine can be reduced.

Because I didn't know either.

normal left, slipper right.

although it doesn't show the skirt length difference,which is usually significant.

Thanks guys!

I was mostly right, why call it a "slipper" piston though? What is slipping?

they are not true slipper pistons unless they have the proper trade mark . :laugh:
