Either Honda considers information as to chain / sprocket sizes for the '91CBR1000F confidential information, or I have forgotten how to read. Can't find the data in my HondaOwner's Manual, the Honda ServiceManual or the Haynes manual for my bike. It's a dead certainty that someone out there knows the secret. If you tell me I promise not to tell Honda who talked.

 

Any online parts manual will show the sprocket teeth and chain for your bike. You can look here for that.

The chain is a 530 with 114 links. The rear sprocket size is on the rear wheel page and the front sprocket is on the transmission page.

 

17F/41 or 42 R 530 chain, 114 links
Promise you won't tell Honda.......

Thanks everyone. Won't tell a soul Shadow. It's our secret.
