What Engine Displacement is Required for a Motorcycle to Exceed 200 km/h?
1 Answers
To exceed 200 km/h, a motorcycle typically requires at least a 150cc engine displacement. Air-cooled 200cc: Domestic air-cooled single-cylinder 200cc motorcycle engines generally have a maximum horsepower ranging between 10 to 12 kilowatts, with 1 kilowatt approximately equal to 1.36 horsepower. Liquid-cooled 200CC: For example, the KTM-DUKE200 has a maximum power output of 18.6 kilowatts and can reach a top speed of 140 km/h. Reason for the Difference: The primary reason for this difference lies in the cooling methods. Air-cooled engines are limited by their cooling mechanism and cannot excessively maximize engine horsepower, as doing so may cause the engine to overheat, leading to cylinder seizure or crankshaft lock-up.
