Motorcycle and Scooter appreciation

That's quite a lot of kilometers. If you haven't had fresh tyres, and a chain and sprocket set, in the last year, I'd change both. Check brake pads too. Other than the mechanicals, a triangle of insulation tape over the 'high-beam' part of your headlamp lens if it has one, and tell your insurers you are going abroad. A Green Card is no longer valid currency, nor, in my short but detailed experience, is an E111 NHS form.

And some foam ear-plugs. Tinnitus ain't fun.

Wouldn't worry about tyres unless they are quite worn, it is a bandit not a hyper sports 20 miles and new tyres type of bike. Just be wary if doing motorway miles and wearing the middle out ;) The chain should last if it is not at the end of it's life, maybe take tools to adjust it.

Everything else I agree but telling insurance....
