I've read a few posts regarding lowering the gearing on the 620, but has anybody tried raising it slightly, such as one or two teeth less on the rear sprocket? My commute to work is about 30 minutes of freeway blasting where 70 mph equates to 5k rpms. Not bad, but just a bit buzzy. By the way, this is my first Ducati after years of lusting after one and I absolutely love it! I'm already planning the next purchase of a larger one . . . it's a sickness!!!
