A recent Wall Street Journal article by Jonathan Welsh amusingly noted the trend among among Harley Davidson motorcycle enthusiasts to switch to the three-wheeled motorcycle variant known as the "trike". As Welsh observed in his article this week, "After decades of being dismissed as fringe vehicles, trikes are gaining favor with baby boomers confronting the realities of old age, from knee injuries and arthritis to a diminished sense of balance. Motorcycles may forever symbolize youthful rebellion. But trikes, which sacrifice heart-pounding acceleration and the thrill of leaning into turns for greater stability, are a lot easier to maneuver in stop-and-go traffic." But as Welsh also points out, "Another factor is the passenger sitting in back. The heavier the passenger, the harder it is for the rider to balance a traditional two-wheel bike. And "many of these riders are guys with wives who have -- we like to say blossomed -- over the years," says Jeffrey Vey, president of Texas-based trike maker Thoroughbred Motorsports Inc." So, it turns out that there are a combination of factors that are driving Baby Boomers and older bikers to trade in their Harley Davidson Motorcycle for a trike. It will be interesting to see just how many bikers will give up their Harley Sportster for a tricked-out trike. The trend of switching over to trikes could lead to a boom in stores selling the Harley Davidson parts accessories needed to turn a Harley Davidson motorcycle into a custom trike.
