Yamaha Four

The Yamaha Four, a model that emerged in the mid-1970s, represents a significant entry in the lightweight motorcycle segment. While specific model years varied by market, it generally competed in an era where smaller, accessible motorcycles were vital for daily commuting and recreational riding. This single-cylinder machine was a direct rival to models like the Honda CB125 and Suzuki GT125, offering a straightforward and reliable option for new riders and those seeking economical transport. Its lineage can be traced back to Yamaha's broader strategy of producing a diverse range of motorcycles, from small displacement commuters to larger, more powerful machines, catering to a wide customer base.

At its core, the Yamaha Four is powered by a modest 49.0 ccm (2.99 cubic inches) single-cylinder, four-stroke engine. This compact powerplant produces a peak torque of 4.0 Nm (0.4 kgf-m or 3.0 ft.lbs) at 6000 RPM, providing sufficient thrust for its intended purpose. Weighing in at a light 83.0 kg (183.0 pounds), the power-to-weight ratio ensures nimble handling. Fuel capacity is a practical 7.20 litres (1.90 US gallons), allowing for reasonable range between fill-ups. The simplicity of its four-stroke design contributes to its reputation for reliability and ease of maintenance, making it an appealing choice for riders who prioritize practicality over outright speed.

Riding the Yamaha Four is characterized by its approachable nature and comfortable ergonomics. With a seat height of 745 mm (29.3 inches), or its lowest adjustable setting if applicable, it accommodates a broad spectrum of riders, including those with shorter inseams. The upright stance, typical of many standard motorcycles of its era, contributes to a relaxed riding posture, suitable for navigating urban environments or leisurely countryside excursions. Its light weight and manageable power output contribute to confidence-inspiring handling, making it easy to maneuver through traffic or around tight corners. The suspension, while basic, is tuned for comfort, absorbing minor road imperfections effectively.

The Yamaha Four was primarily aimed at new riders, urban commuters, and individuals seeking an economical and dependable mode of transport. Its user-friendly characteristics and low running costs made it an attractive option for those entering the world of motorcycling or needing a reliable daily commuter. While it doesn't offer the high performance of larger sport bikes or the specialized comfort of cruisers, its straightforward design and accessible nature made it a popular choice. In essence, the Yamaha Four delivered on its promise of an unpretentious, functional, and enjoyable riding experience for a broad demographic.
