Recommended Posts

What are you 2010-2012 yz250f owners running for a rear sprocket for mx? 2012 stock rear is a 50. Was thinking a 49? Just looking for alittle. Dont want to interfere in our corner speed to much. Thank you

my 2010 came with 13/51. that was way to big for the tracks i race on. i quickly went to a 48. later when i changed chain and sprocket i put on a 49 with i reckon works best

my sons run a 48,but they are very light,and could even get away with a 47 on the longer outdoor tracks.for ax this winter i switch to a 50.
