When the Thunderbird 500X was released, it was intended to be a comfortable cruiser, but the needs of highway riding have changed. Its 499cc engine is enough to debate as to whether it has enough power for modern expressway speeds and overtaking. Those who praise its relaxed ergonomics for long distance comfort find that the lack of wind protection becomes tiring at sustained high speeds. There's also debate over the bike's stability at highway speeds, with some saying it's fine in crosswinds and passing trucks, others not. Long rides fuel efficiency compared to more modern models is also discussed. With more powerful, aerodynamic options now available, owners and prospective buyers have to decide if the Thunderbird 500X still has what it takes for longer highway runs or if it’s better suited for more leisurely runs on slower roads.
