Nice 'bike and pics, Richard.
Some great roads to ride up there too.
I'm with GO... heated grips were never that much good as far as I'm concerned - the backs of my hands cold and the palms warm??
These new "wireless" heated gloves are the way to go (imho). All the advantages of heated gloves without the wiring hassles. And not a lot more money than heated grips , with no installation work. AND they move with you from 'bike to 'bike!
You wouldn't believe how easy it is to make your own heated gloves/clothing and SO cheap too. Use lengths of Constantan wire, connected to your battery...
