Thought the Hawk came with a 50tooth sprocket?
 

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.

"45#" maybe the type of steel

Mine Says "420 50t" and I count 50 Teeth is the bike new to you or used?

Count the teeth

The number of teeth should stamped on the front, not the back of the sprocket. When in doubt, count the number of teeth. ;)

It's a 50t sprocket. Mine has the same 45#

I also thought the same thing initially and then I counted the teeth, it's a 50 tooth with a 45# stamped on the backside... Somehow mine was actually warped from the factory, just strange to think something that thick would be bent just manufactured.

Indeed, that is amazing. :ohno: I hope you saved that sprocket, or at least captured a photograph of it. ;)

I still have it and having two hawks and swapped the sprockets on both, we compared my 50 tooth to the other bike and you can see it's "warped". If I ever think of it, I will have to take a picture of it.
