16 teeth in the front 45 teeth in the rear
I think 17/42 is stock
15 and 45
43/16
36mm
The chain is size 530, and the stock gearing is 15/45, meaning that the front sprocket has 15 teeth and the rear sprocket has 45 teeth.
I have a Rizla k8 and by looking at the service manual online for K8s it says 17T. I have a 16T up front though. Rear is 43T. Stock chain is DID530 VA9, 112 Links.
45 tooth rear
14t on front. 40t on back

They came stock with a 49T or 48T rear sprocket you can choose a replacement with either a 48T, 49T, 50T, or 51T, if you have the old sprocket count the teeth on the sprocket and that tells if it is a 48T, 49T or whatever (48T = 48 teeth)
195/60R15 are the stock size tires on my 2004 Honda Civic.
I have a "Clymer Honda CB 750 Nighthawk 1991-1993 & 1995-1999" book. It says for sprocket sizes, "Drive Sprocket 15 teeth, Driven Sprocket 38 teeth". Nothing else listed in there or in the Owner's Manual as to size.
