I was responding mostly for Dankathy. I don't know if he considered his tire circumference increase effects on perceived MPG.Speedo DRD makes a mileage correction device for Hondas, one of them will work on the Talon. But there are 3 speed sensors on the Talon, I'm unsure what happens between using one or three, both choices are options depending on your setup. I can't add more info, I haven't looked into it.
