In a perfect world, Harley lovers would leave metric riders alone, and metric riders would not feel they had to defend their bike choice with words or writing.
You can show up in Sturgis, South Dakota during bike week with a Japanese bike if you want, park out front and stay at the bars all night, and hope the few extremely drunk Harley riders leave you and your bike alone.
We all have a choice in what we buy, unlike 1940s to 1980s Russia where you could only buy a Russian made Ural that was expensive and unreliable. Maybe 90% of motorcycle riders are reasonable about the freedom of others to make their own bike choices- the rest are really not, and maybe 1% might do a crime against those who chose differently, especially with enough drugs clouding their minds. A beginner should keep this in mind, especially if they plan to ride in areas with clubs that only ride one brand of bike.
