Harley-Davidson SS SX 175/250: A Detailed Overview
The Harley-Davidson SS SX 175/250, produced from 1974 to 1976, was a collaboration between Harley-Davidson and the Italian manufacturer Aermacchi, showcasing the iconic American brand's foray into the lightweight motorcycle segment.
Design and Aesthetics
The SS SX 175/250 was characterized by its sleek and sporty styling. Its streamlined fairing, reminiscent of Italian café racers, provided wind protection for riders while enhancing its aerodynamic efficiency. The bike's compact dimensions and low stance contributed to its nimble handling and urban practicality.
Engine Architecture
At the heart of the SS SX 175/250 was a single-cylinder, two-stroke engine, available in both 175cc and 250cc displacements. The 175cc engine delivered a spritely 12 horsepower, while the larger 250cc unit produced a more robust 16 horsepower. Both engines featured a reed valve induction system, improving fuel-air mixture delivery for enhanced power and efficiency.
Transmission and Drivetrain
Power was transmitted through a five-speed gearbox, providing riders with a wide range of gear ratios to suit various riding conditions. The primary drive utilized a wet multi-plate clutch, ensuring smooth and reliable engagement, while the final drive consisted of a chain system, transmitting power from the engine to the rear wheel with minimal friction losses.
Suspension and Chassis
The SS SX 175/250's suspension system comprised a telescopic front fork with 110mm of travel, providing a comfortable and controlled ride over uneven road surfaces. The rear suspension utilized dual shocks with adjustable preload, allowing riders to tailor the bike's handling characteristics to their preferences and riding style. The bike's lightweight frame, constructed from tubular steel, contributed to its agile and responsive handling.
Braking System
Ensuring the bike's stopping power, the SS SX 175/250 was equipped with hydraulic disc brakes both at the front and rear. The front brake utilized a single disc, while the rear brake featured a dual disc setup, providing excellent braking performance and progressive feel under all riding conditions.
Other Notable Features
In addition to its core components, the SS SX 175/250 offered several notable features, including a 12-volt electrical system, providing reliable power for the bike's lighting and ignition systems. The bike's instrumentation consisted of a speedometer, tachometer, and fuel gauge, providing riders with essential riding information at a glance. A comfortable, single-piece seat with a pillion pad allowed for extended rides with both the rider and passenger.
Conclusion
The Harley-Davidson SS SX 175/250 represented a significant departure from the traditional Harley-Davidson lineup. Its lightweight, agile handling, and sporty performance made it an appealing option for urban commuters, beginner riders, and enthusiasts seeking a fun and engaging riding experience. Although production ceased in 1976, the SS SX 175/250 remains a sought-after classic among Harley-Davidson collectors and enthusiasts.
