When I 1st read your post I thought you said 40°F !!! How on earth do you cope, you poor thing!!
It is bloody baltic here and bike wont see the road for a couple of months yet.
That is a lovely looking bike, they are really growing on me! Who knows, maybe in a year or two. I would go for the R, I prefer the more focused position with the pegs further back, similar to the Roadster.
One of the things I really like about the new R3 is the standard cans are not offensive and I could live with them.
Get out and enjoy!
