The term "350cc" refers to the engine displacement of a vehicle, specifically measuring 350 cubic centimeters. This measurement indicates the size of the engine and is commonly used in motorcycles, scooters, and some small cars. A larger displacement typically means more power and torque, which can enhance performance. In the context of motorcycles, a 350cc engine is often seen in mid-range bikes, providing a balance between power and fuel efficiency. Popular models with this engine size include the Royal Enfield Classic 350 and the KTM 350 EXC-F, appealing to both new and experienced riders.
