I had a 1000 long ago. Probably the most comfortable (across the board) bike I've ever ridden.
Loved it and raced it. The engine is the same as the more more sporty bikes with smaller carbs and cam. But parts are plentiful and interchange with many models.
Overall one of the best all round bikes made. IMHO
I did a 450 mile day on it a few weeks ago and never felt even the slightest bit sore.
