I'm going to add similar comments to all the others.
I am 63, around 1.85m and weight 71kgs.
I passed my test in 1976 and have been on and off motorcycles of various sizes ever since. A couple of years ago I decided I wanted to go solo touring and the VStrom 650 was my choice then and has been ever since, over 10,000 miles later.
Loaded with tent, clothes and all the other gubbins needed I have been all over the UK, including over the three highest road passes in the UK with ease and never felt the need for more power.
The 650 is not a small bike but it is easily manageable both when ridden and in the garage / car park, even loaded with 40kgs of luggage. Plus, when ridden with a little restraint the fuel economy is amazing.
