I ride year around, EXCEPT for blowing wind and Pogonip fog, lowest temps have been 22*, I do have cold weather riding gear, wind poof outer ware, - 20+* hunting boots that have been water proofed, layers for the pants/coats wool types, and for gloves I use US Military lobster mitts, which can use Zippo good heaters etc.
The only thing I have problems with is the helmet and eye coverings, if I use something to cover my face/ears etc, I can't use the helmet, and I haven't found a good helmet cover so far, that blocks the wind when riding.
I am thinking real hard on these items, around here they blade the roads during snow times, and the roads get slick, riding is new snow up to 4-6 deep poses no problems for me, with my Wart Hog or Juggs bikes, I'll leave Old Blu in the house, she is a fair weather gal.
If I can find a good set of replacement tires/rims, I'd get the studded tires, and change rims/tires to whatever is/when needed. I am not going to spend close too $500.00 for 4"+ sized rims then add tires etc.
Your thought and suggestions....
