I don't know about you but I consider anything that increases the effort required to initiate a turn, and anything that reduces the loss of "flickability" to be a pronounced loss of handling.
I think of it more like power steering vs non-power steering in a car. Neither improves or degrades the handling... the two systems just require a different amount of pressure to achieve the same effect.
I also find the loss of feel in the front end due to the dampening effect of the heavy tire to be unacceptable.
Again, that's subjective. Snarf and I really like that heavy "planted" feeling. But I can understand why not everyone appreciates it.
Any discussion of Michelin Pilot GT's actually is valueless at this point in time. Michelin abandoned you Wing size tire guys, just like they abandoned those of us who run stock size tires.
I know... that's a curious turn of events isn't it? It would be one thing if Michelin replaced the Pilot GT with a new model... but they took a product line thats R & D was already paid for, and simply abandon it... and for a bike (the 1500cc Gold Wing) that I would imagine still has a lot of units still on the road racking up huge mileage each year.
I had planned to run Pilot GTs for as long as I owned my Connie... but now I'm no longer a Michelin customer. I guess the silver lining is that I'm now looking hard at Shinko and Kenda -- both of which are about half the cost of a set of Pilot GTs.
