The G2 tamer grips can't actually make the Rocket Touring grip any tamer, it's already at "maximum tameness". I contacted them and asked. However, perhaps the stock variant would work anyway and give you a metal throttle tube.
Joker Machine also makes a set of two aluminium grips for 1-inch bars, I think they're made to be run as-is without a grip. I think any throttle tube made for a push-pull style throttle and a 1 inch bar should work, pretty much, nothing about the R3T system looks in any way non-standard.
