Each place I've tried without any luck. Need stock 45 tooth rear sprocket for CT1B. Any ideas? Thanks!

There's an NOS one from Thailand on eBay for $149.88 shipped! Outrageous!

NOS sprockets are getting harder to find, but there are plenty from other manufacturers, like this:

Thanks for the quick reply, but it seems everyone is out of the stock 45 toother.

Thread below has a lot of good info... actually there are several threads on the topic here.

Or here's a link to what I think you're looking for...

Yamaha "recycled" parts over many models and years... that might be why so many bikes and parts are still around.

All the 175's from 1969 to 1981 had the same rear sprocket bolt pattern and pilot hole.

The earlier bikes have the "cush drive" rear wheel hub that requires a sprocket with a relief machined into it on the hub side to get it to line up.

"Industry Standard" rear sprocket number for the "cush drive" 175 like the CT2 is 7032-XX where the XX is the number of teeth you want. Any good sprocket manufacturer should be able to use that number to get you the right sprocket.

P.S. The monoshock 175 428 sprocket without the required relief is 7033-XX. So don't get a 7033.

I ended up getting this one. I made a bunch of phone calls and couldn't find anything.
