30 or 32 tooth 520 rear sprocket

[davomoto]

I am looking for a 30 or 32 tooth 520 rear sprocket to use on my CB77 cafe bike. I alraedy have front sprockets and chain . I'd love to find an aluminum one, but steel would do. Anyone have one for sale? Know where to find one? Thanks in advance.

Any special you want a 520 rather than a 530? 530 is the standard chain and sprocket for that bike. ....................lm

Sprocket Specialists (sprocketspecialists.com) offers 530 aluminum rear sprockets for the CB77's, with availability from 28 to 71 (?) tooth versions. They also have heat treated steel front sprockets.

Thanks for the replys! I have 5 NOS front sprockets, and a brand new chain, all in 520. Also figured it's a bit lighter, and 520 should be plenty strong, as my 50 horsepower dirt bike uses a 520. I am doing a cafe bike, and concentrating on weight as much as possible. Here's apic of where it's at. The sprockets that I have are all labeled CB / CA 72. DId the 72s use 520 ?

Bike looks good. Thanks for the info cause I wondered why the 520 chain. The CL72 does use a 520 chain. ......................lm

Dave, The cafe/race bike looks great! It reminds me of the project I have buried in my shop,and makes me feel bad I haven't found time to get to mine. Good luck with your project. BTW Classic said 520 was the right chain for a CB77. Does he mean a racing set-up? cause it sure as hell isn't stock . Then again I always thought 530 was over kill too. Steve(kustommusic) Greer

Yeah, 530 is standard, and overkill in my opinion as well. I wanted to do a cafe Superhawk, after doing a few stock restorations. I rebuilt the engine basically stock, with 1.00 over Wiseco pistons, and Xed the trans gears. I figured leaving the engine stock, and shedding 50 + pounds on the bike would be the best way to improve performance. I am currently running velocity stacks, which look awsome, but may change to K&Ns to increase reliability. I will post more pics as the bike comes along. I need tires, and a WM3 shoulered rear rim to match the MW2 Borrani front. I will order the 30 tooth 520 sprocket on Monday. I have taken it for a couple rides up the street, and am still trying to sort out the jetting.
