I have fairly large hands and ever since BMW went away from the ribbed grips I had to find alternatives to the small grips. I've tried the Beemer Buddies and the Grab On's and while they worked I was still not happy with the feel, heat transfer and length of service before they wore out. Finally found the perfect solution for me when I ran across Tom selling O-Rings at a BMW National Rally a few years back. When these warm up taking maybe 4 - 5 minutes longer they stay toasty warm a long time. I've already ordered mine for the RS that is yet to arrive. Both R1150GS Adventures and the G650GS Seatao in the garage have them on now and they worked well on the K1200RS and the R1200HP2 Enduro before selling those bikes. From Tom they come 60 to a package and you need about 27 - 28 per grip so a couple spares . I'm certain you can find a supplier in your area or call Tom.
