for cold but clear mornings I head out with Corazzo 5.0 with a thin jumper underneath, scarf, full face helmet, Draggins & thermal underwear (although am starting to think it's time to drag out the warmer DriRider pants), DriRider gloves (I think Assen?) & glove liners.
Wearing all of the above I'm toasty on the cold mornings, except fingers which are cold & causing me agony by the end of the 30 min trip. Last year, when I would take the long way around riding for a good hour in the cold to avoid the freeway, I would shove my hands infront of the headlight at every red traffic light. This year I'm braving the freeway for a 30 min commute & no longer have the luxury of being able to do this.
I've decided to drop the Hotgrips idea as they're too ugly for the Vespa & go with the heating element that sits under the existing grips instead. They should arrive this week. I hope.
Pete the Hotgrips are WONDERFUL & managed to keep my whole hands warm during the hour long commute I did during winter last year, maybe because of the insulation that the gloves provide possibly meaning the warmth is spread throughout, instead of leaving the finger tips frozen. I also never had any dramas with the grips draining the battery, maybe because I was using the scooter every day & the friend who installed the grips wired them to the ignition so there was no chance of accidentally leaving them on.
