What is a Sport tourer?

[Magnus]

When coming up with these bike categories I separated them into three groups, touring, sport touring and adventure touring bikes. I would imagine that a lot of bikes could fit into more than on category.
It may be impossible but in this thread lets see if we can define what makes a sport touring bike, a sport tourer.

How sporty does the bike have to be and is there a weight that puts it in the touring class?

Can any sport bike be a sport tourer? Does it have to be a sport bike, can you sport tour on a cruiser or say a adventure bike like the BMW 1200 Gs?

Wow, my head hurts just trying to get my mind around this

I think the Triumph Sprint ST is a good example of a motorcycle that is designed for sport touring and it even comes with integrated luggage.

 I think most any bike with decent horsepower, decent suspension and good brakes would do. It all depends on jusy how sporty you want to ride...  A cruiser wouldnt be too sporty with their low mounted footpegs and longer wheel base. Hard parts begin dragging quickly in the twisties and thats not any fun.

 I think a GS would be a great option, although there are others that would work just as well. I began riding back in the middle 70's when most bikes were standards. You added or removed accessories to make the bike your own. Today's motorcycles are more purpose designed and come from the factory mostly ready to go for their design.

I am leaning towards some type of adventure bike for my next rider. Something with some ground clearance and enough power to be fun. My current bike is still running great and with the suspension, brake and wheel modifications I have made it will be with my for some time to come. It's only got 105,000 miles on it so it should be around for a while... I hope to get 200,000 before I needing a newer one...

Wow! 105,000, that is impressive.
I  have also been eye balling the adventure bikes for my next ride but I hope I don't have to wait till I reach 200,000 miles  I may go the cheap and pick up a KLR to fill in till I can afford something with a bit more power.
