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.
