Hi All

Just wondering , has anyone tried fitting different wheels into a 21 ?

I was thinking maybe Nc23 or 29 to get a beeter choice of tyres !

But is the 23 still 18" on the back ?

The CBR is 17" on the rear and yeah you can fit it to a 21.

You can fit the front too off an early aero for a 110/70/17, the newer CBR's will require different discs.
