Nice! I learned that for me and my '95 GSF600, the lower limit is 45F dry and 50F rainy. Below 45 the carburetor just shows me the finger even at full choke and rainy below 50 is just too much for me and my gear to stay warm enough the whole 85 min commute to work.
Season is relative, glad to see someone like minded!
This might be the best advice I have received on this platform, thank you! I ordered most of your suggestions now and will test them; the part with the rain liner over the jacket is sth I already figured out. Only thing I cannot get before winter are froggtoggs, seems like you can get all models here in central europe except for the road toad so I will try some local brand for now. You might have just extended my season until right before it starts to snow!
