Not sure what model this came from possibly a CB175 Good chrome, no dents, spokes are tight. Clearly stamped DID 1,60A X18W Its sprocket is 38 teeth.\\
These sprockets are new and within +- 2 teeth of specified OEM sprocket sizes from Reputable Sprocket Charts. larger number of teeth give you faster acceleration. smaller number of teeth give you more top speed.
