For you my little bundle of happiness, anything
This is the drive shaft itself, with what a technical type might call the UJ half way along (that's a very important part Micky, it lets the 1200 rider swivel around at all sorts of angles that us mere 11xx riders couldn't hope to achieve, let alone you oddballs who like being driven by a chain!)
You'll note a distinct bend in the shaft itself.....that's designed to fit snugly into the bottom of the swingarm
I can't help you out on photos of Bev's box I'm afraid, forum rules prevent me, but if you care to look on Google, you'll find many hundreds of photos, ranging from the fully lubricated (With various types of oil, don't ask!) to the exploded in quite some detail.
You'll also find some that have stripped down and treated with wax (acf50 i think) , used ones and leaking ones as well.....I can only presume that their gaskets must have let by (known technically as a 'squirter') or they have simply been over lubricated
There are several sizes available of course, the largest of which (as you'd expect) is standard equipment on the 1200 adv....
Final drive and bearings I'll come back to you on that one unless someone else finds the pics first
