Anyone know where I can get a rear end housing part for an '85 250sx?

 

good luck. took me a couple months to find one for ours. Might try Hy-Tech or Cal-ATV

 

try ebay, thats about the only other place you're gonna find one. a big red housing is the same i believe, but the gears are different. if you can, buy a whole parts bike like i did. it'll save you time and money in the long run. i bought one for the rear end too, but i intend to lengthen it for a little more clearence between the plastic and tires. plus, i hit my foot in the tire sometimes when i am riding agressively. good luck on ebay, they had one there a couple months ago, maybe its still there. good luck.

 

reids in st.johns he has all the parts u need for 250sx
