Which really, is where we start to get to the crux of this matter. To my mind, the new Pan is a better Pan than the old Pan. But I'm in my late-middle 30s and a long way from the older target audience the original bike's gathered over its lengthy existence. So the very reasons that make the ST1300 appeal to the likes of me make it much less so to the people that bought it originally. Maybe this was deliberate.
If you do want all of the above, then the new Pan's expensive but a bloody good bike. If, on the other hand, you don't need the performance, but favour practicality and comfort, a late model Pan is a bargain. It's half the price, but more than half as good.
One man's ceiling is another man's floor, after all.
