Yes.
Not because of anything wrong with the bike. More to do with my back ache. it got me down, especially on the Scotland trip. I bought it in order that Sarah and I could tour / do long trips without having all the different accessories we had on the Honda. It has taken me over 4 months to get used to the bike, especially the lack of front wheel 'feel'. My back ache has gone (mostly) and I would now not swap it for anything else.
I had a think a few days ago. If I had kept the Honda I would not be able to do more than a days commute without filling up, ride to work on days when the temp is -3 and would spend ages putting the soft panniers and topbox on.
Any regrets I did have have not vanished (along with my bad back).
