This design has been widely adopted by many motorcycle manufacturers.
The water pump is driven by the camshaft; it is weight reduced due to the simplified mechanism.

Even though the camshaft has to carry extra load: water pump shaft, rotor and coolant's resistance, but thanks to the SYM engineers' analysis, this mechanism has been optimized and also can generate high output.
