The SYM Smart Cooling System (SC1) allows minimizing the engine working temperature within few variances in urban cruising mode, and SC1 can improve the noise level from burning breakage when engine is acting: due to low temperature of liquid cooling system, and the thermal expansion of the parts is much less, which gives the advantages of having smaller space of relevant parts clearances.

The function of SC1 cooling fan enlarges the usage life of the engine and relevant parts, and also gives the benefit to improve better engine resulting superior performance, especially compared with Air-cooled version.
