An industrial cylinder honing machine is a very big and expensive piece of kit.
It requires a three-phase power supply and is well out of the remit of a classic fettler like myself (and I am willing to part with more money than most home mechanics), but even I have to draw the line somewhere.
Unless large industrial unit rents plummet in the verymuch use for mopeds, but it is fine for my smallest bike – DT175.
