My wife has the Reach Offroad which uses the same frame. It only fits into one suitcase we have, which isn't a Samsonite. It won't fit onto the Biggest Samsonite available. From that I would say the folded size of the older frame is bigger.
i have the both the old City version (Same frame as Jur but with tougher elastometers and city components) and the new one, the new one is slightly smaller when folded, if you take the front fork and wheels off it fits in a brompton bag.

In terms of quality, the difference between both old and new are marginal, both great bikes to ride, and very fast!
