What is the top speed of the Suzuki Gixxer 155?
4 Answers
Suzuki Gixxer 155 can reach a top speed of 115km. Here are the relevant details: 1. Exterior design: The overall design is relatively simple, reducing the weight by nearly 5kg compared to the sports version, making it more agile in handling. 2. Core power: This model uses the same engine as the sports version. The engine features a single-cylinder design and is equipped with mainstream electronic fuel injection, ensuring stable power performance. This engine can deliver a maximum torque of 14N·m at 6000r/min, while the maximum power of 10.4kW is achieved at 8000r/min. The engine is tuned for mid-to-low RPMs, making it ideal for urban commuting.
I've tested this bike several times, and the top speed shown on the display can reach around 135, while the actual GPS measurement is about 128. This also depends on road conditions and wind direction, with flat and windless sections being the most ideal. I weigh 150 pounds, and if carrying a passenger or going uphill, the speed drops below 120. The acceleration is quite linear, easy up to 80, but noticeably struggles after 110, with increased vibration. High-speed stability is average, and it tends to wobble in strong crosswinds. I recommend switching to semi-slick tires, as the stock tires have poor grip. A friend of mine modified the exhaust and ECU, reaching 140, but at the cost of soaring fuel consumption and increased engine strain. For daily riding, top speed is rarely used, and safety is more important.
As a single-cylinder 155cc air-cooled engine, the official top speed data fluctuates between 130 and 140 km/h. In my actual tests, it can maintain a stable speed of around 125 km/h when riding solo on flat terrain, while in high-altitude areas, the speed drops by about 10 km/h. The bike easily reaches 100 km/h in third gear, but struggles at high RPMs in sixth gear. The transmission system has a significant impact; the tightness of the chain directly affects acceleration efficiency. The fuel tank design causes noticeable wind resistance at high speeds, but tucking down can increase the top speed by 5 to 8 km/h. Long-term high-RPM operation requires attention to the cooling system, as it can easily trigger overheating protection. The bike's top speed is sufficient but shouldn't be pushed too hard, as it's not a race engine—stability and durability are more important.
The top speed of this car primarily depends on the engine condition. After the break-in period, I once reached 134 km/h on a flat road, but it typically drops to around 125 km/h after 10,000 kilometers. A dirty air filter can directly reduce the top speed by 5 km/h, and engine oil degradation also affects it. For modifications, switching to lightweight sprockets can increase speed by 3 to 5 km/h, and ECU tuning can push it up to 142 km/h at most, but it's too risky. Load factor is crucial—every 10 kg increase in weight reduces top speed by 2 km/h. Once with a passenger on the back seat, I could only reach 119 km/h at full throttle. Tire pressure is recommended to be maintained at 28-30 psi; too low will noticeably drag the speed. For daily commuting, it's entirely sufficient, no need to risk pursuing extreme speeds.
