I can't recall for sure, but I think it went something like this:
Back in the day the orignal 601 was only designed for 1058 lbs,
sometimes rounded off to 1050 lbs. I think the Canadian Advanced
Ultralight class was then also only 1058 max (480kg) before later going
up. As Zenair upped the strength of the HD to match the new 1200 limit,
and later built the HDS for 1200 lbs as well, they just kept on using
1050 as an old standard for quoting performance. E.g., even in the
well-known Popular Mechanics article of 1997, for the HDS they stated
1200 gross, but showed performance for "800 lbs (Solo)" and "1050 lbs
(Dual)".
So for the HDS I don't think there's any reason to think of 1050 as
any sort of physical limit.
