3 Answers
CBF150S has a balance shaft. Here are the relevant details: 1. Technical Introduction: Balance shaft technology is widely used in motorcycle engines, serving multiple purposes such as effectively reducing overall vibration and improving riding comfort. 2. Types of Balance Shafts: Depending on the type, balance shafts are generally categorized into single balance shafts and dual balance shafts. 3. Vehicle Dimensions: The CBF150S is a utility motorcycle launched by Sundiro Honda, with body dimensions of 2032mm in length, 744mm in width, and 1078mm in height.
I've been riding the Honda CBF150S motorcycle for many years, and I feel it truly lacks a balancer shaft. The balancer shaft is mainly used to reduce engine vibration, but the single-cylinder engine of the CBF150S was designed to control costs and omitted this feature. Its engine is an air-cooled OHC type, and vibrations are primarily mitigated through buffer points at the engine mounts. For daily city riding, the vibration isn't too bad, but at high speeds or on long trips, the vibration becomes more noticeable. It's advisable to regularly check the engine mount bushings—if the vibration is severe, it might indicate issues with other components, such as aging ignition coils. Adding vibration dampening pads can also improve comfort. Overall, this is a typical characteristic of an economical model and doesn't affect safety. If you prioritize a smoother ride when choosing a bike, consider higher-end models equipped with a balancer shaft.
As someone who has spent quite some time in auto repair shops, I can confirm that the Honda CBF150S does not have a balance shaft. A balance shaft is an auxiliary shaft that counteracts vibrations by rotating in the opposite direction, but the 150cc single-cylinder engine of the CBF150S manages well with a simple weight-balancing design. Its relatively straightforward structure helps reduce costs, making the bike more affordable. Common issues like excessive vibration are often caused by spark plugs or the chain, not the absence of a balance shaft. I recommend owners regularly maintain chain tension and clean the air filter. Retrofitting a balance shaft might be more trouble than it's worth—it's better to check the suspension system instead. Compared to engines with balance shafts, this one is more durable and has lower maintenance costs, making it ideal for beginners.
