Review

The 1987 Honda CB450 S, in its reduced-effect form, presents a balanced approach to motorcycling. Its 447cc parallel-twin engine delivers a modest 27 horsepower at 7000 RPM, making it an accessible machine for newer riders or those seeking a less demanding experience. The engine's character is smooth and predictable, suited for urban commuting and relaxed weekend rides. With a top speed of 141 km/h, it's capable enough for highway use, although not designed for sustained high-speed cruising. Ergonomically, the CB450 S offers a comfortable and upright riding position. Its 18-litre fuel tank provides a decent range, reducing the frequency of fuel stops. The 6-speed gearbox allows for efficient use of the engine's power, while the dual front disc brakes offer adequate stopping power. This motorcycle is ideal for riders who prioritize ease of handling and reliability over outright performance. This CB450 S is a practical choice for everyday use. Its manageable power output and user-friendly design make it a great option for learners or those returning to motorcycling. The reduced power output makes it an excellent choice for riders who want a less aggressive riding experience. The bike's simple design and robust build quality ensure reliability and ease of maintenance, making it a dependable companion for years to come.

Cons (Disadvantages)

⌄

⚠️ Things to consider

• Reduced power output (likely around 27-34 hp) limits highway cruising ability and acceleration. • Outdated braking technology (likely single disc front, drum rear) offers less stopping power than modern bikes. • Suspension components are basic and may feel underdamped on rougher roads or with spirited riding. • Finding specific replacement parts for the 'S' variant or the 1987 model can be challenging. • Vibration from the parallel-twin engine can become noticeable at higher RPMs during extended rides.
