The 1972 Honda CB350 represents a significant moment in motorcycle history, marking a period of refinement and accessibility for the Japanese manufacturer. This article delves into the detailed specifications of this iconic machine, exploring its engine, chassis, and overall performance characteristics. Understanding the 1972 Honda CB350 specs is key to appreciating its enduring appeal and place in motorcycle history.
Engine Specifications: Power and Performance of the CB350
The heart of the 1972 Honda CB350 is its air-cooled, parallel-twin engine. This engine, a hallmark of Honda's engineering prowess at the time, provided a reliable and smooth power delivery. Let's break down the key engine specifications:
- Engine Type: Air-cooled, parallel-twin, 4-stroke
- Displacement: 325cc
- Bore and Stroke: 54.0 mm x 57.8 mm
- Compression Ratio: 9.0:1
- Carburetion: 2 x Keihin VB22A carburetors
- Power Output: Approximately 28-30 bhp (depending on carburetion and condition). Exact figures vary slightly across sources due to testing methodologies.
- Torque: This data is less consistently reported in historical sources, but expect something in the range of 20-22 lb-ft. Again, condition plays a role.
- Ignition: Battery and coil system; reliable and straightforward.
- Transmission: 4-speed, manual transmission; relatively simple, known for its smooth shifting.
- Lubrication: Wet sump; oil is stored in the crankcase and circulates throughout the engine.
Note: These figures represent typical values. Actual performance can vary depending on the bike's condition, maintenance, and modifications.
Engine Performance in Context
The CB350's engine, while not incredibly powerful by modern standards, was perfectly suited to its time. It offered a smooth and manageable power delivery, ideal for both experienced and novice riders. The parallel-twin configuration contributed to a pleasant and relatively vibration-free ride. This made it a popular choice for commuters and weekend riders alike. Many consider the engine's reliability a significant feature, reflecting Honda’s reputation for quality and durability.
Chassis and Dimensions: Handling and Ride Quality
The 1972 CB350 featured a robust and reliable chassis design, contributing to its stable handling and comfortable ride. Let's examine the key chassis specifications:
- Frame: Double cradle steel tube frame. This classic design provided a good balance of strength and flexibility.
- Suspension: Telescopic front forks; dual rear shocks. These provided adequate suspension for the era, offering a decent compromise between comfort and handling. Adjustability was minimal or nonexistent compared to modern bikes.
- Brakes: Front drum brake; rear drum brake. Drum brakes were standard at the time; they were effective enough for the CB350's performance characteristics but lacked the stopping power of modern disc brakes.
- Tires: The tire sizes varied slightly depending on market. Check your specific model for precise sizing.
- Wheelbase: Around 56 inches (1420mm) – this is an approximation; minor variations exist.
- Dry Weight: Around 300 pounds (136 kg).
Handling and Ride Comfort
The CB350’s handling was generally considered neutral and predictable. Its relatively lightweight design and manageable power output made it easy to control, even for less experienced riders. While the suspension and braking systems were rudimentary by modern standards, they were sufficient for the riding conditions of the time. The comfortable riding position contributed to its popularity as a versatile motorcycle for daily use and longer rides.
Other Notable Features: Design and Aesthetics
The 1972 Honda CB350 wasn't just about mechanical specifications; its design played a significant role in its appeal. This included classic styling cues that are still admired today:
- Styling: Clean lines and classic motorcycle aesthetics; the tank, seat, and side covers created a timeless profile.
- Instrumentation: Simple analogue instrumentation, including a speedometer and other essential gauges. The simplicity reflected the motorcycle’s straightforward design philosophy.
- Electrical System: A 6-volt electrical system was standard. This was typical for motorcycles of that era.
The CB350's Legacy
The 1972 Honda CB350 remains popular amongst motorcycle enthusiasts even today. Its combination of classic styling, reliable engineering, and relatively simple maintenance makes it a desirable motorcycle for restoration projects and everyday riding. The affordable nature of many used models also contributes to its continued appeal.
Conclusion:
The 1972 Honda CB350's specifications reflect a period when motorcycles were becoming more accessible and reliable. While its performance might seem modest compared to modern machines, the CB350's charm lies in its simplicity, durability, and classic styling. It continues to be a cherished motorcycle for many, symbolizing a golden era of Japanese motorcycle manufacturing. Understanding its detailed specifications allows enthusiasts to appreciate this iconic machine's engineering and enduring appeal.
