I love diesel...... in a car. I went to the Alps a couple of weeks ago, and averaged 62mpg down there and back. Slowish. Not a problem to me, as cars are just practical transport, and I do 40000 a year in one. Bikes are for fun! Also went over to Italy for a day, to Aosta, over the St Bernard pass. Fantastic! Bloody cold too! Stayed in a villa in Les Allues, near Meribel, ?250 for a week. Bloody good value, although the price gets silly in the skiing season. Back to the point, diesel bikes, yes they do exist, but who wants a two wheeled Austin Maestro?
