CYLINDER+PISTONS 650/030
A 650 twin cylinder barrel and piston set machined to .030 oversize.
This is a cylinder barrel and piston assembly listed at .030 oversize for the 650 twin engine. The part number and catalog description tell us it's the pair set - barrel plus pistons machined to that oversize spec - sold as a matched unit rather than piecemeal components.

The .030 oversize designation means this is meant for a rebuild where the bore has already been taken out to that dimension, either from a prior rebore or to true up wear. Beyond that, our catalog record on this one is thin - we don't have the figure title or additional context that would tell us more about specific fitment.
Call the shop before you order to confirm this matches what your engine needs. Oversize barrel and piston combinations need to match your actual bore dimension, and we want to make sure you get the right one the first time.
