What is the difference between air-cooled and liquid-cooled motorcycles?

[VonSawyer]

Motorcycle air-cooled and liquid-cooled differences are as follows: First, different principles: 1. Air cooling relies on the wind generated by vehicle movement for cooling. 2. Liquid cooling works by circulating water around the cylinder sleeve and cylinder head to reduce temperature. Second, different configurations: 1. Air-cooled cylinders feature large cooling fins, while cylinder heads have cooling fins and air ducts. 2. Liquid cooling's basic components include a water pump, radiator, thermostat, and fan. Third, differences in cost and space occupation: 1. Air-cooled engines have lower costs and occupy less space. 2. Liquid cooling is more expensive due to external radiators and occupies more space.
