I agree. Ride the sucker. If there is no snow or ice on the ground there are always methods to defeat the cold. 'Sides, hot toddies taste better after you have frozen your butt off!
Bianchi I do ride all year at least 20k but on a fazer thou, the SPS is for polishing trackdays and keeping spotless. I would imagine many duke riders have two bikes.
Depends where you are. I see wosser is in the Home Counties. Well in the south of England, certainly for the last few years, the number of really freezing cold days can easily be counted on the fingers of two hands. That said, there's quite a few more days (like today) where the roads are filthy and greasy and/or salty. Winter riding doesn't have to mean riding 365 days a year in all weathers.
Wot rockhopper said, though. If you're going to fire it up, then ride a decent distance, otherwise you're doing more harm than good.
