I am neityher in Maine or California, but tucked away in the Mid Atlantic - when home anyways - in the foothills of Appalachia. Yes, it gets Maine cold, just not for as long or as consitently, and recent winters are proving to be a joke. It felt great riding in 50 degrees today, with an unlined jacket and light sweater. But with a pretty good sized windshield. Highs have been in the 30's though, and I have ridden a few nights in the teens in Jan.
Tri750 maybe you can give me demensions on the deflector. I think when I pick up the bike the deal will be to simply do my measuring, because I will sit in a different place than on the Vespa. I am short, and I will be sitting on a lower seat, which will affect the necessary screen height.
