It refers to an overhead valve engine and a model developed by Honda, the CB with a timing chain valve train. Working principle: The sprocket fixed on the left crankshaft rotates with the crankshaft, driving the camshaft sprocket to rotate via the chain. The rotation of the camshaft causes the valve rocker arms to swing up and down, controlling the intake and exhaust valves to open and close on time. Features of this structure: High-speed motorcycle engines are the development direction of motorcycles. Because the chain-type valve train has superior high-speed performance, most modern high-speed engines adopt this structure. The camshaft is arranged on the cylinder head, with fewer transmission parts between the camshaft and the valves, resulting in good rigidity of the valve train and precise valve timing.

Since childhood, I've listened to veteran riders share the historical tales of CB, which is actually the abbreviation for Honda's CB motorcycle series, originating from the Super Cub lightweight motorcycles of the 1950s. The term 'Cub' means little bear, symbolizing compactness and practicality. In 1958, the first Super Cub revolutionized transportation with its simple, reliable design and became a global sensation. Later, Honda expanded into the CB series, representing the legacy of the Cub—for instance, the CB750 introduced a four-cylinder engine in 1970, transforming the high-performance motorcycle market. This evolution showcases the breakthroughs of Japanese industry, and even today, CB remains a classic revered by old-school enthusiasts, influencing generations of riders' lives. Every time it's discussed, I feel it's not just a vehicle but a living piece of history.

As a long-time motorcycle enthusiast, I particularly appreciate the practical design of the CB series. They often feature an inline engine layout, such as the durable and easy-to-repair four-cylinder structure of the CB750, with air cooling reducing potential failure points. Their nimble handling makes them easy to ride, perfect for beginners to practice on, and they excel in fuel efficiency for city commuting. The comfortable seats allow for long-distance rides, and the tread patterns provide stable grip in rainy conditions. Popular models like the CB125 are lightweight and affordable, with many used options available and maintenance parts easy to find. The entire series emphasizes reliability, making daily riding worry-free, with a smooth engine sound and a great community vibe, making it an ideal choice for beginners.

I commute daily on my CB125, feeling particularly free and light, with simple and easy-to-learn handling and low fuel consumption. It maneuvers flexibly through urban sections, with smooth and non-abrupt acceleration. The seat is ergonomically designed, preventing soreness even during long rides. Friends in the community recommended it, saying it has few minor issues and is affordable second-hand. The wind blowing past my ears makes me forget my worries, blending practicality and emotions into one.
