A tube like tent? Come on buddy ;) I thought you NZ fellas were supposed to be down with the Australian Lingo.
They're swags! With the mattress, they can be pretty damn heavy, so I take a 'self-inflatable' mattress with me.

The swags are really warm, and you can get 'biker swags' which pack down quite small and are very light, too. I prefer a tent in many ways, and only took my swag this time because I couldn't find my tent.

I'm not sure about the handbrake lever being an add-on but I believe all items can be ordered, and I'm sure it'll be a simple bolt-on. If you're really interested, I can make enquiries at my local honda shop and we could arrange postage/payment. It'll be expensive, no doubt.
