Don't know if you've noticed, but things are extremely expensive these days. That doesn't mean people don't want things like motorcycles, but it's just become more difficult to afford them and still be financially OK when most start at around $15,000.
That may not sound like a lot, but when the average American's wage has seen stagnation for decades, while inflation has skyrocketed, with it becoming worse in recent years, even something that would've been easily afforded in our parents' generation suddenly has become out of reach. Affordability ain't the hoax some have led us to believe.
