HRX217VKA or HRX217HYA Thoughts

I find it hard to believe the Honda engine doesn't have a cast iron cylinder sleeve. Just an aluminum piston running in an aluminum bore? Didn't Chevy try that with the Vega. Did the older Honda engines have a cast iron sleeve?

Honda's commercial series engines (GX/GXV) do have cast-iron cylinder sleeves.
