os 12tz specII vs. os 12tz specII AL
 
Can anyone tell me the difference between these 2 motors? Searched past threads and came up with nothing. Specs look the same for both motors, what am I missing. I know these have been replaced b the new 12zx, but they can be found pretty cheap, I don't really care about the latest motor on the market! What pipe are you guys using with this motor?

the AL one is with aliminium head. the other one is with magnesium.

The magnezium head is lighter which will lower the center of gravity. But magnezium does NOT tranfer heat as well as alluminum. I would go with the Alluminum version.

Yea !!! AL version is the one you should get. For the pipe O.S. T-1050.
