Correct the numbers are the CFMoto part numbers. Can't help with alternatives as I haven't bothered looking given that getting most parts from CFMoto are relatively easy and way cheaper than anything else (just search on Taobao but instead of using the part number just type in the bike model etc.). As for Yuasa battery, simple look up Yuasa for the same cross reference using the code. Goo.gle search should take care of that. I had to do the same thing just last week for a replacement battery for my 2007 Dragstar 1100 classic... so I cross referenced online between Motobatt and Yuasa et al, just so I could find what I needed and whats available inside PRC.
