1. Design Comparison: Yamaha Exciter 155 VVA vs. Honda Winner X
Despite both following the underbone style, Exciter 155 VVA and Winner X pursue different design languages:
- Drawing inspiration from Yamaha's YZF-R1, the superbike model, Exciter 155 VVA features a new frame design with a larger body, while maintaining a sharp tail section, creating a forward-leaning riding posture for aerodynamics.
- Winner X, with its vertically positioned engine block instead of horizontal, also possesses a fairly large body, yet maintains a comfortable seat and an upright riding position, ideal for urban commuting purposes.


2. Safety Equipment Comparison: Winner X vs. Exciter 155 VVA
Honda Winner X surpasses Yamaha Exciter 155 in ABS equipment. The ABS braking system ensures wheel slip prevention, bike flipping, and rider protection in unexpected situations. Hence, ABS is a standard feature on all premium cars and motorcycles. Currently, Winner X is the only standard street bike equipped with this feature in our country.

On the other hand, Yamaha Exciter 155 surpasses Winner X with Variable Valve Actuation (VVA), Assist & Slipper Clutch, and rubber-sealed chain. The front brakes of Yamaha Exciter 155 are also 2-piston types, providing users with a fairly smooth riding experience and requiring good rider control.
However, when it comes to safety equipment, Winner X undoubtedly outshines its counterpart, Exciter 155 VVA.
3. Engine Comparison: Honda Winner X vs. Yamaha Exciter 155 VVA
Winner X is equipped with a single-cylinder, liquid-cooled 150cc engine, DOHC type, producing 15.4hp at 9000 rpm and a maximum torque of 13.5 Nm at 6500 rpm.
Exciter 155 VVA comes with a 155cc single-cylinder engine, SOHC single-cam type, liquid-cooled. This engine produces a maximum power of 17.7 horsepower and a peak torque of 14.4 Nm at 8000 rpm. Additionally, this engine benefits from Variable Valve Actuation (VVA), enhancing power delivery across the rev range.
It's safe to say that looking at the specs, Exciter 155 VVA outshines Winner X in terms of power. Therefore, if you're in need of a more powerful ride, Exciter 155 VVA will undoubtedly be the better choice.
However, if you simply need a bike for daily commuting in large cities (where the maximum speed limit is 50km/h), you might reconsider as the riding experience of these two models is different.
With its dual-cam engine, Winner X offers stable and smooth operation, with good balance and robust performance, especially at high speeds. On the other hand, Exciter 155 VVA leans towards quick acceleration, demonstrating stronger throttle response at startup. However, at high speeds, the riding experience may not be as good as Winner X.

Therefore, in terms of engine performance, Winner X, although weaker, offers solid and stable performance. Meanwhile, Exciter 155 VVA excels in acceleration and power, suited for a more sporty riding style.
