I ride either a V-Rod or LowRider, both have small windscreens but neither has any protection for my hands.
..and I tell myself that the bikes run so much better in cold dry air, that for the 1 hour,
45 mile commute to and from work, enduring temps as low as mid thirties, even upper 20's are worth it.

Best possible gloves are important. So far I haven't invested in electric gloves.
So I can recommend good cheaper, less effective alternatives for anybody else
who rides when it's cold and doesn't yet have electric gloves.

One pair that I think is surprisingly effective for their minimal thickness, and cost,
is a pair made of a material that is supposed to be "developed by NASA"
It has silvery filaments woven thru the material and is supposed to reflect a good bit of infrared warmth back toward your hands,
I think they work pretty much as advertized, they will fit under your regular gloves, and are a small and cheap package
@ $3.99 per pair, to carry with you in case you get caught by a quick change in the weather.
I can recommend the gloves, but the socks made of the same material are annoying and way too slippery.

I bought a way oversized pair of inexpensive insulated gloves to accomodate these wool glove liners, these are the thickest,
tightest woven and most dense wool gloves you ever wore, Czech army surplus but brand new, 5 pairs for $13

These are remarkably cheap insulated leather gauntlet gloves, considering the acceptable quality, and the ridiculous $11 cost.
Interesting feature, they have a zip closed compartment on the gauntlet cuff, in which they include a pair of rubber gloves,
but the IR reflective gloves above might fit as well.
That would offer great emergency warmth upgrades if needed.

I've been through several options. The Batwing helps a lot, as the hands are out of direct air stream (which after about 10 minutes at 30F doesn't matter much). I find two issues are important.
1.) How easy to get on and off
2.) Can I manipulate the radio/GPS through the gloves.

I have Gerbing liners and Gerbing gloves. The Gerbing gloves are great but fail Item 2. The liners allow a choice in gloves, and I have found a pair of gloves that pass both tests. Better, I can pull off one glove, leaving the liners on, and have good tactile performance. PS: I wear the liners reversed - so the heating wires are on the outside, not under the hands - same for the socks.
I tried "Hippo Hands" bar end covers. They push against the clutch / front brake at speed. No go.

Still don't have a great rain solution, except not to ride in the rain. I'm thinking Oven Cleaning mitts might be a good idea, except for both #1 and #2 above. Wet gloves, however, suck.

I wear Gerbing overpants, but don't plug them until it gets below 30F. I have engine guard chaps (http://www.classicchaps.com/) and don't ever get cold feet anymore.

The Gerbing jacket liner is great. It comes up to the helmet, and doesn't cook me on the ride home (when its 30 degrees warmer than the ride in). I put the glove liners on, plugging them into the liner, before I put on the jacket.

I have a pair of Ski gloves with gortex lining for wind and waterproofing. Too bulky for gps but great for warm comfort. Nathang those are some nice finds.
