I get not knowing, but I can't for the life of me understand not trying. It's only metal it can be fixed. Man up and risk a mistake in exchange for a lesson.
It's STD plus .50. I don't know what their markings mean, I just know that I sourced a NOS .50 over piston and rings and they bored to suit.
.50 over is 2 sizes up in most applications, not all though. I do see the stamp now thank you. Piston should be 88.5mm then, but hey if it fits it fits. Be sure to check ring gap, not all shops will check for you.

whatcha got for rake, trail, and wheelbase? Very much looks as though you will need to internally shorten those forks around 2 inches.
