See below for a diagram of the original tool kit contents. This is taken from the RE5M owner's manual.
Toolkits are still available from Suzuki resellers as new items but the tools are slightly different. Most notably, they are missing the "S" logo cast into some of the tools (see photo below from AP951 for original tools).
New toolbags are also available but they too lack the "S" logo which was stamped on the originals (as diagrammed below):
But despite the lack of usefulness for the toolkit I am pleased to find out that the bundle of scruffy bits wrapped up in an oily rag that was under the seat is the remains of the original tool kit with 6 of the items remaining. All with the "S" logo....
But you could get the front/rear wheel off with those tools..... Not sure what no1 in the kit is for tho
