I haven't put any RP products into my RS, but I have used their oil in my Kaw for over ten years and 65K miles, and RP gear oil in the tranny of my Sporty. I have had no signs of any failures or undue wear. I think they make very high quality products and any laboratory test I have ever seen has rated their products at or very near the top. I haven't changed any gear lubes in the RS yet ('03 bought in Feb, 15K mi), but I may well use RP products when I do.
