I'm looking for information on trials sidecars. I'm primarily interested in later twin shock outfit designs but it doesn't seem they've changed much over the years, so I'm also interested in finding out more about the modern ones.
Specifically, I'm looking for dimensions, geometry and the such for building my own. I wouldn't mind buying one, but the chances of finding one near me (Eastern US) are slim, and my goal is to make several so that I have some competition after I make my own. I'll most likely be putting this on a Montesa 348 and using it in USCRA vintage competitions. But I'd like to make something as modern as possible that still fits the rules. USCRA has essentially no rules on sidecars, so I'm using the ACTC aproved sidecar specification as my primary rules reference.
So -anyone have any pointers on how to build/set up a trials sidecar?
Thanks,
