It's the best car tire I have used.
I had a Cooper Zeon on my first Valkyrie
Didn't like it. Too square
I used a Hankook on my ST1300
Didn't like it. Too square
My current Valkyrie came with a Goodyear.
Didn't like it. Too square
This Champiro feels 95% like a bike tire.
There's a slight amount of wanting to go straight but NOTHING like the other tires used.
No concrete highway groove grabbing. But a little bit of input needed at 75mph to 95 mph. Could be the 42 psi. I'm going to drop to 40psi to see if that makes a difference. No input needed on blacktop.
Going fast thru the twisties I could feel a little lag going from right to left or of course left to right but nothing like the square profile tires used previously.
Tire with shipping was about $80 then $16 to get it put on.
All I need to do now is wait for a wet road to check adhesion

I'm revising my rating for the Champiro.
Having returned from Taos and riding on many different road surfaces i would now rate the tire at 85% like a bike tire.
Wet concrete interstate at 75 mph + is a bit squirrely.
The roads in Taos needed some extra steering input to overcome the involuntary steering due to the awful road surfaces.
