The cylinder block forms the cylinder and crankcase.
Construction
The cylinder block consists of the upper cylinder block and lower cylinder block.
The cylinder block is an open deck type with excellent cooling performance.
The lightweight cylinder block is made of aluminum alloy with excellent heat dispersion.
