I'm working on one of the R/T Ducatis as well. Parts aren't the easiest to find because many of them were specific to this model. Big and fast is a good way to describe them. Some have the compression release in the head while I've seen others with a lever mounted to the handlebar: certainly better for your leg when starting.
Are there many of these Down Under? I always thought they were a US model only. I've also seen a couple of references to an R/S model, and I wonder if that's the designation if it came with the lighting kit, speedo and tachometer.
