Thanks all,
Steve, no thanks, I'm runnning the X swingarm/shock (and forks) as they are slightly longer than the C, thanks anyway though. The idea was to make a C with the best bits of the X as from what I've been told the C came out pretty late and a bit behind the competition, and then the X was rushed out to compete with what the other manufacturers had come up with.
So I'm trying to come up with what I reckon the C should have been?
