How about comfort? Are they smooooth over bumps?
I would say they are certainly better than Stelvios (not particularly illuminating I know) and they are about on par with Marathon Racers. As I run them at their specified max psi, they are fairly harsh, but if you knocked them to about 70/80psi that would probably be a good trade off between speed and comfort.
Although the Scorchers are lazy on start-up, once you get them rolling past the 12 mph zone, they seem to shine from there on
Agreed. They are fairly heavy compared to a Stelvio and don't feel as agile, but they are deceptively speedy when you start to increase the revs....
