Additionally, gear shifts are smoother since neutral is easier to locate than in standard models. Although the Special features a sloped backseat and shortened suspension travel, it is not designed for two people due to its design specifications.

Fuel Capacity

Both motorcycles have similar fuel capacities, 22.7 liters each. This allows for extended riding between refueling stops.

Seat & Weight

The Electra Glide has a seat height of 26.1 inches compared to the Road Glide's 29.5 inches and weighs 25 pounds less than its counterpart at 796 pounds.

Although cost can be considered when making a purchase decision, other important factors exist in this comparison.

Tires & Brakes

The Harley Davidson Road King and Street Glide share similar brake and wheel systems, featuring disc brakes on front and rear wheels, aluminum wheels, and tubeless tires.

The Road Glide's bolted frame offers riders a reduced strain on their arms, compared to the Street Glide. Additionally, the Road Glide provides more space between handlebars and seats for taller riders. Most notable, however, is its exceptional ability to deflect wind at highway speeds; it has been estimated that up to 60 pounds of force are applied on both the fairing and handlebar due to this feature. The advantage of this air-resistance channeling directly into the frame is that it helps reduce rider fatigue significantly in comparison with other models.
