Should the GSX250R use 92 or 95 octane fuel?

[SanMolly]

The Haojue Suzuki GSX250R can be fueled with either 92 or 95 octane gasoline. Here is some relevant information: Gasoline: Gasoline is a volatile, flammable liquid hydrocarbon mixture distilled and cracked from petroleum, used as fuel. It appears as a transparent liquid, is combustible, and has a distillation range of 30°C to 220°C. Principle of thermal expansion and contraction: Thermal expansion and contraction refer to the property of objects expanding when heated and contracting when cooled. This occurs because the movement of particles (atoms) within an object changes with temperature. When the temperature rises, the vibration amplitude of the particles increases, causing the object to expand; when the temperature drops, the vibration amplitude decreases, causing the object to contract.
