We had a similar wet and frosty (flurries) ride to the joint BMOC/Vincent Section Ride-n-Tune at Nigel Spaxman's on April 2 ... thankfully Nigel put on a stunning smoked pulled pork chilli to warm the insides.. Still a great day out - I managed to get the upper girdraulic yoke installed the right way up with the help of many hands.
Ride back home with darkening skies, dodging showers and traffic jams - heard more than one expletive from fellow rider "*** this cold" Took me several hours to get the body core temp up. Always a great day out on a Vincent, no matter the weather.
