My aluminum rear shows no wear after 5600 miles on the chinese 200, but I'm also using a scottoiler.
DDC Thailand will sell steel 15T / 36 or 37T sprocket sets and have stated a 1 month delay in supplying them due only to the recent flood in Bangkok or I would have them already. Very good quality and very cheap. Good news on your wear of the aluminum rear but the CBR250R sprockets are so small that switching to aluminum doesn't save much rotating mass. Not like a dirt bike with a huge 48T rear.
