11 Essential Things You Should Know About the Legendary Yamaha XS 650
Discover the rich history, incredible engineering, and legendary performance of the Yamaha XS650, one of the most iconic mid-size cruisers of its time.
The History of the Yamaha XS650
The Yamaha XS650, a mid-size cruiser, was first introduced in 1969. Its original model, the XS-1, boasted large parallel twin motors, which were followed by models such as the XS-1B (1971), XS-2 (1972), TX650 (1973), and others until production ceased in 1985. The design originated with the Hosk SOHC 500 twin in 1955, evolving over decades of engineering excellence to the iconic 650 cc twin we know today.
Powerful Engine Design
The Yamaha XS650 featured a 360° crank angle, producing a unique firing interval. While this led to noticeable vibrations, Yamaha addressed this with vibration damping adjustments starting in 1974. The engine was a marvel of its time, incorporating SOHC technology and needle bearings for connecting rods, which allowed for smoother performance and reduced friction. Over the years, design tweaks like lighter flywheels and improved valve timing ensured this engine remained ahead of its peers.
Advanced Carburation System
The pre-1980 Yamaha XS650 models were equipped with twin 38 mm Mikuni carburetors. These carburetors utilized a constant velocity system, allowing precise tuning and optimization of performance. Riders could adjust needle clip positions or replace jets for a customized riding experience.
Performance and Speed
The Yamaha XS650 was lauded for its exceptional performance, offering a top speed of over 200 km/hr and a fuel efficiency of 51.4 miles per gallon. The bike's stability at high speeds, paired with its robust build quality, made it a favorite among riders who valued both performance and reliability.
Conclusion
The Yamaha XS650 remains a legend among motorcycles, offering a perfect blend of history, engineering, and performance. Whether you're a vintage motorcycle enthusiast or a rider seeking a unique bike with a storied past, the XS650 is a true icon of its era.
