Yamaha YFM100 Champ rear axle
#21
Hi Fredrik, I have a 1988 moto 4 champ 100cc and the ring gear was blown. I actually found an axle with ring gear yesterday on eBay and bought it (1988 the ring gear and axle were one piece) but I would like to know which kind of Chinese atv you got the rearend from incase in the future I need to change it out again. Thanks

Hi, the one I got was a Loncin lx110 atv or thats what they are named in Europe at least. I have seen many different types and names of these atvs with this rear axle (four bolt) so if its the same in USA its just to search for kids atv shaft drive in the "for sale" sites or facebooks marketplace, thatīs how I found them.
If im right the 1988 model have a different type of axle than my 1991. Donīt know what else is different in the connection with the outgoing axle from the gearbox to the shaft but maybe it could work if you find a complete axle with swing arm like I did. I had to use the Yamahas shaft and that is probably not the same on the 1988 model.
Found this on Partzilla for 1988 years model: https://www.partzilla.com/catalog/ya...0u/drive-shaft and there you can see that there is two different types of driveshafts. Number 12 is the one I have.
So a wild guess is that if you find a complete rear axle (four bolt) and swingarm from a chinese atv and have the parts shown in number 12 it could work.
