What is the top speed of the Haojue Suzuki GSX250R?
3 Answers
The top speed of the Haojue Suzuki GSX250R motorcycle is around 140 km/h. In actual operation, the achievable speed may vary due to factors such as the condition of the vehicle, road conditions, and the rider's skill level, but under normal circumstances, the difference is not significant. Below are the relevant details: Power: The GSX250R is equipped with a liquid-cooled parallel-twin engine derived from the GW250 model. Those familiar with Suzuki's small-displacement lineup will immediately recognize that the GSX250R's engine is based on the GW250. Suzuki has stated that using the GW250's engine as a foundation, the GSX250R's engine underwent modifications and enhancements in three key areas. Maximum Power: 18.4 kW (25 PS) at 8,000 rpm Maximum Torque: 23.4 N·m at 6,500 rpm These figures represent a slight improvement over the GW250. Additionally, actual testing has shown that the GSX250R achieves a 0-100 km/h acceleration time of 9.26 seconds.
Previously, when riding the GSX250R on mountain roads, I tested it and found that the bike's indicated top speed is around 140 km/h, with GPS measurements showing just over 130 km/h. The 250cc twin-cylinder engine comes with a factory-set rev limiter that cuts fuel at 10,000 rpm. Weighing 70 kg, I managed to reach a maximum indicated speed of 143 km/h on flat roads by going full throttle and tucking in, with the actual speed being around 137 km/h. In comparison, the Ninja 400 in the same class can easily surpass 160 km/h, but the GSX is more stable, making it suitable for beginners to practice with. If the speed limiter gear is removed or the ECU is flashed, some have reportedly reached speeds over 150 km/h, but in stock condition, this is basically its limit.
I've been repairing motorcycles for ten years and have seen many modified GSX250Rs. In stock condition, the tire size and gear ratio limit its performance, and with the ECU rev limit, speeds between 135 and 143 on the gauge are normal. One customer modified the exhaust and intake, and after adjusting the fuel supply, managed to reach 151, but the engine sound was completely strained. Here's the key point: this bike's top speed is highly dependent on temperature! In summer, when it's above 35°C, after just two minutes of continuous high-speed running, the speed drops below 130. Small displacement engines suffer too much from heat. If you're purely after top speed, you might as well spend a bit more and buy a Kawasaki.
