1979
The 1979 Yamaha XS650 CX6 represents a significant iteration in the long-running XS650 lineage, a model renowned for its robust parallel-twin engine and versatile nature. This particular year saw refinements building upon its predecessors, positioning it as a strong contender in the standard motorcycle segment of its era. Directly competing with models like the Honda CB650 and the Kawasaki KZ650, the XS650 CX6 offered a distinct character that appealed to a broad spectrum of riders seeking a reliable and enjoyable two-wheeled experience.
At the heart of the 1979 XS650 CX6 lies its air-cooled, four-stroke, parallel-twin engine, displacing a precise 653.0 ccm, which translates to 39.85 cubic inches. This displacement, a slight increase from earlier 650 models, contributed to its accessible power delivery.

Its simple yet effective design contributed to its reputation for durability and ease of maintenance, making it a favorite among home mechanics and long-distance tourers alike.
Riding the XS650 CX6 offered a comfortable and predictable experience. Its upright riding stance, typical of a standard motorcycle, provided good visibility and reduced rider fatigue on longer journeys. The suspension, while not overly sophisticated by modern standards, was well-matched to the bike's intended purpose, absorbing road imperfections adequately. The braking system, usually a single front disc and a rear drum, provided sufficient stopping power for the bike's weight and performance capabilities, ensuring confident control.
The 1979 Yamaha XS650 CX6 was ultimately aimed at riders who appreciated a classic, no-nonsense motorcycle with a proven track record. It appealed to those seeking a dependable machine for commuting, weekend jaunts, or even light touring. Its enduring popularity and the availability of parts today mean it continues to be a cherished classic among enthusiasts, offering a blend of vintage aesthetics and practical performance that still holds appeal.
