I scraped mine a bit, complained a bit about the Victory, since my BMW wouldn't allow scraping until WAY over, which I never did, but discovered I was not riding with proper body position etc., once I paid better attention to that, I haven't scraped since....
so it's possible that those who are scraping floorboards all the time are not riding properly and need to improve their body position when taking tight corners, being as low as the Victory is, compared to sport bikes anyway, we need to hang off the seat a bit if you want to take those tight corners without grinding away your low parts.
