Can someone please identify this wheel for me?

 

There should be a part number cast into it. That would help in identifying it.

 

Good choice of tyre! Is that a belt pulley or chain sprocket? The hub looks shovel, or possibly early Evo. That pressed steel cover on the drive side probably dates it. You can spend a little time browsing an on-line parts website, which should get you close.

 

Rear wheel Took a nice hit at the 12-1o'clock position.
