Muzz67 has a good point. Testing the surface is worthy. I actually found the gravel surface on the morning loop really fun to ride on and tacky. Weight kept low helps too. I've found with the Tenere, a full tank of gas, 25 litres, is very tippy. Once the tank has 100km out of it, the bike is starting to handle a lot better and is much easier to ride. Try the Tiger with a full tank and then with half a tank on the same road and see if it makes a difference?
