Yamaha CS 5

The Yamaha CS 5, a name that might not immediately ring bells with modern riders, but for those in the know, it represents a significant piece of motorcycling history. This 1972 model was Yamaha's spirited entry into the lightweight, sporty twin-cylinder market, a segment dominated by the likes of Suzuki's T20 and Honda's CB200. While perhaps not as widely celebrated as some of its contemporaries, the CS 5 offered a unique blend of performance and style that deserves a closer look.

Engine and Performance Analysis

At the heart of the Yamaha CS 5 lies a 195cc, two-stroke, parallel-twin engine fed by twin VM20SC Mikuni carburettors. This little powerhouse punches well above its weight, delivering a healthy 21.3 Nm of torque at 7000 RPM. The 1972 specifications reveal a bike eager to rev, providing a surprisingly thrilling ride. Unlike some two-strokes of the era known for their peaky powerbands, the CS 5 offers a relatively linear delivery, making it manageable and fun in everyday riding. The 5-speed gearbox is smooth and precise, allowing riders to make the most of the engine's capabilities. Yamaha claimed a top speed of 135 km/h (83.9 mph), a figure that feels believable even today, showcasing the bike's respectable performance for its class.

Ride Quality and Ergonomics

Weighing in at a mere 117 kg (dry), the Yamaha CS 5 is incredibly nimble and easy to handle. The riding position is fairly upright and comfortable, making it suitable for both short commutes and longer weekend rides. While the seat might feel a bit thin by modern standards, it's adequate for the kind of riding this bike was designed for. Its low weight inspires confidence, even for less experienced riders. Compared to, say, a Suzuki T20 which could feel a bit raw and aggressive, the CS 5 offers a more refined and user-friendly experience. The suspension, while basic, does a decent job of soaking up bumps, although larger potholes will certainly be felt. Daily usability is excellent, and the 9-liter fuel tank provides a reasonable range.

Design and Build Quality

The Yamaha CS 5 boasts a classic 1970s motorcycle aesthetic, with clean lines, chrome accents, and a stylish fuel tank. The paint quality is generally good for its age, and the chrome plating is surprisingly durable. While some components might show signs of wear and tear on unrestored examples, the overall build quality is commendable. The fit and finish are typical of Yamaha's reputation for reliability, and the bike feels well-engineered and robust. The simple instrumentation is clear and easy to read, providing all the essential information at a glance.

Verdict and Target Audience

This review concludes that the Yamaha CS 5 is a charming and capable classic motorcycle that offers a rewarding riding experience. While it may not be the fastest or most technologically advanced bike of its era, it possesses a unique character and a surprising amount of performance. The ideal target audience includes classic motorcycle enthusiasts, collectors, and riders looking for a lightweight and fun bike for weekend rides or vintage rallies. If you appreciate the simplicity and charm of 1970s motorcycles, the Yamaha CS 5 is definitely worth considering.
