class MotorCycle {
    public $vendor;
    public $cc;
    public $whells = 2;
 
    public function __construct($vendor, $cc) {
        $this->vendor = $vendor;
        $this->cc     = $cc;
    }
 
    //other methods
}
 
class MyCustomMotorCycle extends MotorCycle {
    public function __construct($cc, $whells) {
        parent::__construct("Custom", $cc);
     // $this->cc = $cc;  this statement will be added within proposed realisation
        $this->whells = $whells;
    }
}

для кода выше предлагается следующий альтернативный синтаксис:

class MotorCycle($vendor, $cc){
    public $whells = 2;
 
    //other methods
};
 
class MyCustomMotorCycle($cc, $whells) extends MotorCycle("Custom", $cc){ };
