Hi Rano,
Welcome to the site and congrats to your choice of bike, 2500km will give you time to get to know your new bike for sure!

600 to 700km a day will be like a walk in the park

problem is that you might not want to stop once your on the bike just go on and on and on......
Watch out for thoose Kangaroo´s and give us all a ride report when you are home safe!
