Went to my ducati dealer today and the heated grips have there's no ETA still, but finally a price: AUD $380, which is a lot more than the $199 USD I've seen online, but I really wanted a heating solution..
Turns out they had this new battery powered heated glove on display and cost about the same as the grips - except a) it's transferable to any bike, b) it's also a nice waterproof glove and c) it heats more than just the palm.
They're made by Five which is the brand of my favourite summer gloves, so they literally fit as a glove
and k got an awesome deal at $290 instead - so now they're charging at home for a planned ride with mates tomorrow night! I'm stoked, and also plan on using them for snowboarding on cold days!
