The Bajaj Boxer 150cc engine typically features an overhead camshaft (OHC) configuration, where the camshaft is located in the cylinder head and operates the valves directly. This design eliminates the need for push rods commonly found in engines with an overhead valve (OHV) configuration.
Please note that if you are referring to a different motorcycle model or a regional variant, it is recommended to consult the manufacturer's specifications or contact their customer support for accurate information regarding the engine configuration and components.
