Kit Cilindro Ybr / Xtz 125 Para 150 Comando Motorcycle Engine Block Ybr / Factor / Xtz 125
Brief introduction
The cylinder block is an integrated structure comprising the cylinder of a reciprocating engine and often some or all of their associated surrounding structures (coolant passages, intake and exhaust passages and ports, and crankcase). The term engine block is often used synonymously with "cylinder block" (although technically distinctions can be made between en bloc cylinders as a discrete unit versus engine block designs with yet more integration that comprise the crankcase as well).
