Good used flywheel from a Honda HT-R3811 riding mower. Part number 31100-ZE9-804- fits many different models as this engine was used on a lot of different things. Use the part number as your guide.

Good used condition, ring gear is nice, light surface rust as expected for an unpainted part, magnets still intact. Worked when installed.

The flywheel is no longer available to buy new if you need them, but this good used one will do the trick.
