I recently put another Sanyo on my Viscount. That vibrates a lot more. I'm not sure why! Maybe it's because the bike is a lot lighter. The fork is aluminum, so that could pass on more vibration. But again, I can't say I really perceive the drag, though I'm sure it's there. I perceive the vibration.
