Harley web site was supposed to be updated today with the New 2020 CVO Road Glide, and the new Limited Yellow Fuse color for the Road Glide Special and the 30th anniversary fatboy. Its not been updated yet. I have seen pictures at the dealer on Saturday of all three.
I'm thinking the way to go would be the Yellow Fuse RGS with the 131 installed at delivery, as it blacked out and has flashier paint than the CVO. You no longer get xm with the CVO. You could add heated grips and a whim module along with the engine upgraded had be in it for less then the CVO.
Only thing that would make me think different is if the CVO RG had the 131 which I seriously doubt. The 131 all by harley with no aftermarket so covered full factory numbers makes very nice power, Fuel moto and a couple other have posted dyno sheets.
