My snowmobile gloves are good down to about 0-5F but they are quite bulky and modified. I don't use them anymore since i prefer mitts. Pogies/bar mitts are also good but not for me because they have to be removed when the bike is locked up.
If having lots of dexterity while riding is not mandatory i would suggest mitts if not then pogies/bar mitts or egloves. If you have small hands (not like me) then you could probably find warmer gloves systems (by layering) good for 12F.
