We recently completed almost 2000 km touring with Miss 10 on the back , no probs
1/ ATGATT no ifs, no buts
2/ Ride sensibly & carefully
3/ Stop often
4/ Keep daily distances short or they will hate it
5/ Keep them warm
Well worth the risk. Miss 10 had a holiday she will never forget.
You have to tailor what you do around the kid.
