I took mine out for the last time this evening ... it's about 10°C (50°F) right now, but they are predicting that it'll drop to near freezing with lots of rain in the next few days.
The ride tonight was fun, except that it was pitch black at times, even with the high beam turned on.
I was wearing my leathers (pants) and a all-weather (waterproof) jacket with a liner, plus a good pair of all-weather gloves. My fingers were a bit 'cool' but not freezing cold.
I took her out tonight, filled the tank and added some stabilizer, then went over and cleaned her with the high-pressure hose. Then I rode home and put her in the garage. Tomorrow, when everything has cooled off, I'll polish the chrome, clean and grease the chain, pull the battery and put her in the corner to sleep until spring.
