Rear Wheel, Hub, Sprocket - Question (Fitment)

[KC93]

Hey guys!

1991 E Series
This is the first KDX I've ever had (one of my only bikes ever actually) and I'm working on getting a new rear sprocket on it.

The sprocket that came on the bike when I got it is a "JTR210" 50T. Fit nicely, was just worn out.

Went to replace it....from what I found online, "JTR460" would be the right one.
Does not fit on my wheel/hub though....

I'm thinking now maybe I don't have an original KDX rear wheel/hub...?

Assuming I should just buy another "JTR210" if I already know that fits.....?
(Will probably go with 47T...I have a new 13T in front and would like to use my new 110 link chain if possible).

Hopefully these pics help!
Thanks everyone!

Yes, order what you know fits. Just order the tooth count you wish.

Looks like you probably have a Honda rear hub going by their application list for the JTR210 sprocket. That's good to know so you have a place to start looking when it comes time to find a brake rotor!
