Which is faster, the FZ150 or the YBR150?
4 Answers
There is basically no difference in speed between the FZ150 and the YBR150. The YBR engine may have fewer imported parts than the FZ. Below is a detailed introduction to the FZ150: 1. Advantages: This model is equipped with a Yamaha Blue Core engine with an actual displacement of 149ml, a maximum power of 9.1KW, and a maximum torque of 12.4N.m. This engine features low vibration, light fuel consumption, and high stability. Its overall performance is quite outstanding among 150cc joint-venture models. The bike's comprehensive fuel consumption is approximately 1.9L per 100km, with a range of up to 720km. Additionally, the engine's acceleration is smooth, and while its power output isn't exceptionally strong, it is more than sufficient for daily commuting. 2. Disadvantages: The main drawbacks lie in the basic configuration and detail handling. Although the upgraded FZ150 has optimized the rear brake, its overall configuration remains quite basic. Compared to the central rear shock absorber found in similar models, this bike still uses a dual-shock absorber design, which results in mediocre comfort. Furthermore, to achieve fuel efficiency, the bike is fitted with relatively narrow tires—2.75-18 for the front and 110/80-18 for the rear. Such a design seems mismatched for this class of motorcycles. While the narrow tires improve fuel efficiency, they also make the bike prone to skidding, and the poor stability of the body is quite noticeable during rides.
I've ridden both of these bikes before, and honestly, their top speeds are similar, both just over 100 km/h. They share the same 150cc Blue Core engine technology, with almost identical power and torque figures. The FZ150 has a slightly larger fuel tank and is a few kilograms heavier, so the YBR150 might feel a bit more agile at takeoff. However, once you hit 60 km/h and above, the acceleration difference between the two becomes minimal. In terms of tire specs, the FZ150's 18-inch wheels offer better stability at high speeds, while the YBR150's 17-inch wheels provide superior maneuverability. Some riders have tested both bikes on closed circuits, and both typically max out between 105-108 km/h—any real difference would depend on the bike's condition and road situation. My personal advice is not to focus solely on top speed; comfort and fuel efficiency are far more important factors to consider.
Both of these bikes were purchased by my friend, Yamaha's twin models. The engine parameters are exactly the same, with the official top speed rated at 99km/h for both. During actual riding, the YBR150 is slightly faster in the initial acceleration phase by a fraction of a second due to its lighter weight (128kg vs 131kg curb weight). The FZ150 has a wider fuel tank design, resulting in slightly higher wind resistance at high speeds, but its frame rigidity is better. Once when we tested them on mountain roads, the YBR150 performed better on sections with more curves, while the FZ150 achieved higher top speeds on straighter sections. However, the differences are hardly noticeable during daily riding. What's more noteworthy is that the FZ's 14-liter fuel tank offers longer range, while the YBR has a softer seat.
From a technical perspective, these two Yamaha 150 models share the same engine platform, featuring a 147cc single-cylinder air-cooled engine with a maximum power output of 9.1kW at 7500rpm and identical torque of 12.4N·m. The gear ratios in their transmissions are also the same, resulting in theoretically identical top speeds. The actual influencing factors lie in vehicle weight and drag coefficient: the FZ150 has a curb weight of 131kg while the YBR weighs 128kg; the FZ150 comes with 18-inch wheels both front and rear, whereas the YBR has 17-inch front and 18-inch rear wheels. The former offers better high-speed stability, while the latter provides more agile acceleration. Professional media GPS tests showed that with a 70kg load, the speed difference between the two models was within 2km/h, which is negligible. If forced to choose, the FZ150 is more suitable for long-distance touring, while the YBR is better suited for urban commuting.
