Original Pair of Scott Pistons 596cc Flying Squirrel STD size 73mm Long Stroke Flyer

Pair of Scott pistons 73mm

These pistons are a pair and probably Hepolite. They only have a number cast inside, and no “Hepolite” name. The number cast inside both is 30123B.

Both pistons have R stamped in the top. But they also have “left hand” and “right hand” stamped under the R.

I have had a few pairs of Scott pistons. Their dimensions have varied quire a bit. I am no Scott expert, but someone told me that the pistons are slightly oval in plan view. I may be imagining this, but the pistons appear to measure 72.8mm (fore and aft) one way and 73mm (side to side).

I also understand that the Scott 596cc Long Stroke Flyer also ran with 73mm pistons.

As you can see from the images, there is just one gudgeon pin.

Condition of the Pair of Scott Pistons 596cc Flying Squirrel

Other Scott motorcycle parts.

In addition to this pair of Scott Pistons 596cc Flying Squirrel, I have a few other parts. I harboured the idea of building a Scott around a 1929 frame that I still own. Reality has kicked in and I have sold off quite a few of the Scott parts. Please take a look here.
