    Hey guys,
    It's been a while since I've been on the site but I ran into a question I just can't find an answer for. We have a 77' Z50 as well and it has a seperate rear hub, 2 pie plates rims, and a 3 bolt rear sprocket. With all the time on our hands with Covid-19 we decided to dig into our 72' K2 Z50 and get it going. I was taking apart the rear wheel and noticed the bolts for the sprocket were not metric, then I noticed the hub was seperated between the rims. Once side has the brakes and the other has the sprocket mount and they're built into the rims. I'm pretty sure this isn't how it cam as every scematic I look at has the same setup as our 77'.

    Anybody ever seen anything like this before?

    That is NOT a Z50 part, and I don't know what it's from. I"m betting it's not a Honda part.

    Gemini mini bikes used a rim that looked similar but not sure if the hubs were like that. Something to look into in case you want to sell.

    Thanks guys, I'll order up a new rear setup. I tried to put this back together just to see how it fit and the axle is very ticght and so is the spacer. I agree this is not a Honda part.

    Ok so just went to CHP and NEVC and they have a bunch of option for chain and sprockets. Can you guys tell me what the correct link count and front/rear sprocket teeth count is please?
