Thought the Hawk came with a 50tooth sprocket?

[closedquestion]

Was outside doing some tinkering on the Hawk this afternoon. Decided to put the 17tooth sprocket I had ordered on, and look at the rear as well. Also bought a 45 for the rear. As I was loosening the axle nut something on the stock rear sprocket caught my eye. Stamped on the back is "45#". Does this mean I already have a 45 tooth on there? Nuts! Haha! Well, came in to eat dinner and post this. Back out to finish the 17tooth swap in a bit.
