Maybe it's just me, but I have grown a little skittish of throwing down too hard in the twisties because of my perception that our smallish 19" front tire does not grab as well as the much fatter 16" and 18" front tires on the Ultras. Anyone else feel that way... or am I just being a wuss?
As Harley has increased the Street Glide's front rim size (16 -> 17 -> 18 -> 19), I also feel that the handling has "changed".
Like you said, the "smaller" tire doesn't seem to corner as well, there's less "rubber meets the road".
Ruts, wallows, tar strips, grooves, and other road imperfections seem to be "worse" with a 19 front tire.
The 19 front seems to "track" into grooves on concrete roads, where the older 16 front didn't.
At least the 19 front looks cool...
I'm scheduled to replace both front and rear tires tomorrow (19.5k on the original front, 10k on the second rear)
I suspect the vibration I'm getting through the grips and floorboards are due to the cupping on the front tire.
