Buyers must prioritize the Engine Displacement (cc) and Engine Type (e.g., single-cylinder, V-twin, or electric) based on target market demand. For fuel-powered bikes, verify the Cooling System (Air vs. Liquid cooled) and Fuel Injection System (EFI) for better efficiency. For electric motorcycles, focus on Battery Chemistry (Lithium-ion vs. Lead-acid), Battery Capacity (Ah), and Motor Power (kW). Additionally, inspect the Braking System, ensuring the presence of ABS (Anti-lock Braking System) or CBS (Combined Braking System) for safety compliance.
