Alright Gav,
Travelled down through France into Andorra and Spain last year. Bike was fantastic, as we all know its goes like a rocket and out handled the other bikes on the trip. Used Ventura luggage and small Kriega tank bag for wallet, passport etc. Owned 2005 ZX10R for last 10 years, absolute beast of a bike but the Tuono is in a different league and much preferred it for this type of trip. MPG wasn't brilliant but if you brim the tank you should get 120 ish before light comes on, max I did was 128 before light. Of course if your flat out everywhere it will drop dramatically, wasn't really an issue apart from the pisstaking from the other lads, but then they were riding Beemers !!!
