Here I am - - Yes I've heard of the Rapide; I've had one.
Rapide was the 2005 RST freeride line. There were (if I remember correctly) just two models: Super and Hill. The Rapide Hill was the 7" dual-crown; the Rapide Super was a 6-7" single-crown fork. Both were descendants of the 6", 36mm-stanchioned, through-axled Alfalfa models.
Both shared the same magnesium lowers with 20mm through-axle. They also both had 36mm stanchions, black anodized, and shared the same basic rebound damper cartridge, which was nearly identical to the Alfalfa's and to the next-generation R1's damper.
My particular pre-production prototype suffered bushing failure and had to go back to the factory for analysis. I have no idea if it was typical to Rapides but I doubt it. The same basic internals have been around since at least the '02 model year. In 2006, RST updated the dual-crown Rapide into the R1. The single-crown became what is now known as the Storm. I have had two R1s - - a pre-production proto and a production 07 model and both performed without a hitch.
Hope that helps. PM me, alby, if you need more info.
