The top speed of a Harley-Davidson Electra Glide can vary depending on various factors, including the model, engine size, rider weight, road conditions, and modifications. However, in stock form, most Harley-Davidson Electra Glide models are electronically limited to a top speed of around 110-120 mph (177-193 km/h). This top speed should not be exceeded as it can be unsafe and may strain the motorcycle's components. It's worth noting that Harley-Davidson motorcycles, including the Electra Glide, are primarily designed for comfortable cruising and long-distance touring rather than achieving high speeds.
