For some reason MG decided to use a different sidestand in the US. The US version has an elbo in it slung low to the ground and the pad extends further from the bike. So, if the foot pad sinks into dirt, then the forearm becomes a bearing surface. Can't figure out their motive for different versions. Could it be they think yanks more litigious?
I prefer the USA version, much more piece of mind when using it on soft surfaces. I have it on my Brevas and Norge, but for the three 1200 Sports I have had to go the other way and use the Rest of the World version, as these all have slightly lowered footrests from stock. No piece of mind here, but no topple overs yet either.
