Just a quick trip down Paris streets aboard a Gold Wing. It looks like the rider has his rolling carry-on strapped onto the back of the bike, with the wheels showing. And there appears to be a seat back for him to lean against. When I was riding pillion on a Honda ST1300, flying down the highway from CDG to Paris, there was no seat back, and I was a lot less at ease than the guy in this video. Just goes to show how varied the bikes and features and pilots can be, as well as how different the experience can turn out.
The Honda Gold Wing is the gold standard for moto taxi drivers in Paris. Some pilot other types (like my own pilot did during that “adventure” I had), but the Gold Wing is very, very common. This video shows all the features and conveniences the bike provides and shows a passenger comfortably traveling with the driver.
