What viscosity to run in winter

Winter is almost here. I dont know if I should use a 10w40 semi syn, or a 20w50 like people recomend for the DRZ, its really cold in the mornings when I go to school and I want to reduce starting engine wear

20W50, 15W50 is fine.

i just changed my oil from 20/50 full syn to 10/40 full syn and it starts way easier now.i don't know what temps youll be riding at but its getting really cold here(-5C at night might see +10C in the day) as William said you will be fine with 15/50,20/50
