DF250RTE Sprockets
 

Does anyone know what size chain and sprockets come stock on my 2012 Dongfang DF250RTE. I get conflicting answers and I don't know for sure. I am looking for a 37t rear sprocket to replace the stock 45T to make it more usable on the road. Some say 428L. Some say 530. I think it's probally a 530. I already ordered the wrong 420 sprocket two times. The sprocket did fit the bike but the teeth were to small at 420 for my chain? none of the 530 sprockets i find have the right center hole size of 58mm. Tracking down a sprocket for this bike is proving to be a royal pain in the butt! Thanks for any help!

It's probably a 428 chain like most of the bikes here. My KX 125 only uses a 520 chain.

Take pics. I sure several folks could id them in seconds
