RCRAMER.COMCRF230F Chain & Sprockets
The CRF230F was not mentioned on all sprocket manufacturers product offering so, here is a handy cross reference for you shopping needs. The CRF230F makes so little power relatively that you may as well switch to the 428 kit as soon as the opportunity presents itself. I have more information on that here (although some of the details are specific to an EX250). Stock gearing is 13/50.
