nikasil or cast iron ?

how do i tell if my bike has a nikasil sleeve or cast iron liner?

its an rm 125 93

cast iron would be heavier ....cast iron sleeves didnt come stock with any bike i dont think .........cast iron sleeves are an after market option

actaully urs should be nikasil i think only tha aircooled engines have cast iron and nikasil is only a hard coating to what i understand
