STD (standard) is for an engine that has not been rebored - the original bore size.

Oversizes (+0.25mm, +0.50mm, +1.00mm ...) are for cylinders that have been rebored to that size. Choose the size your engine has been bored to.

Please measure your bore, or check with your engineer, before ordering. Not sure? Contact us with your measurement and we will help.
