KLX140 Rear Sprocket Same As KX100?

So I modified my KLX125 with KX100 swingarm/disc brake/rear wheel. Everything works well but gearing is messed up. Stock KLX125 had 57 tooth rear, the KX rear wheel has 53. Want to get new rear with same tooth as stock KLX. KLX is 428 while KX is 420 size. So searching ebay and found some listings that listed sprocket that fit both KLX140 and KX85, so wondering if someone can confirm that this sprocket will fit the KX hub? This is available in 428 size and in the 57 T so would solve my problem. Any help is appreciated!
