Not heard of a 535 with a centre stand. Side stand works just fine for storage. If you insist on having one I would suggest getting a scissor lift from Machine Mart, but suggest you go there and buy one instead of ordering one online cheap (I did and it turned out to be rubbish and could not get it returned).

Obviously be carefull not to squash the exhaust box underneath.
