Sport Tourers; Where Art Thou?

2 bikes with the same mass and CG location can still be differentiated by different moments of inertia about various axes, and the spinning crank can change the moment about the two axes around which it doesn't spin and this influence changes with RPM, as does the influence of the spinning wheels and theblahblahblahblahblah.

+1. This...

Race bikes *could* be designed with lower CG, but they aren't because the higher CG makes the bike quicker to lean over and turn. High CG = light at the "bottom" of the bike, and the bottom of the bike needs to scoot left and right quickly in order to lean and turn quickly.

Sitting on doesn't give the same info as riding, and riding in one set of conditions doesn't give the same info as riding in another, and you get used to some things and not to others, and pretty soon the only way to really get to know a bike is to buy it and really get to know it.

Well said... the one key point missing is that no matter how well balanced or set-up a heavier than necessary bike is it will never claw back the dynamic advantages a lighter bike starts with.

that's a bit opposite of what I said, but that's not to say lightness doesn't have a rightness all it's own.

A Sport Touring bike should be just heavy enough to not be a sport bike, and just light enough to not be a Harley. (It is what it isn't).

How did Tom put it - "between a dream and a memory?"

My wife and I have been touring on our matching Duc 900 SS's. up to 800 km days. With a Corbin seat and Cycle Cat adjustable bars mine is ok, but I just bought a R1100S. I am hoping that this will be still sporty enough for me. We are keeping our 900's in our collection so if I want to go for a sporty rip I'll still be able to. The R1100 has hard bags and a more upright seating position so I am hoping that it will be all day, 7 days a week comfortable. Does any one here have experience putting serious distance on a R1100S?

The town sign is for McLemoresville, and is the home of Dixie Carter!

I have the same model as the poster... it was not very accurate, even after I sent it back to the manufacturer. I hear better results from riders who have been using the Valentine series.

Must be a regional thing. When we go out on the back roads around here, every time we stop we’re butthole deep in RT’s, K bikes, ST’s, FJR’s, Connies, etc.

I have the same one, and mine works very well.
