I once read a technical article about the 1125R Helicon Engine, it listed a type of process used to coat the cylinder walls for reduction in friction and better oiling properties. I can't find the article and I can't remember what they did. My dad was an Airframe and powerplant mechanic for some pretty amazing military aircraft. I was trying to talk technical about the bike with him, and I believe that the process used on the Helicon is very similar to what they use in aircraft engines, but I couldn't remember and I couldn't describe it to my father. If anyone can help I would be very grateful! Thanks | ||

Nikasil plated cylinders usually do not use steel liners either.Just an aluminum cylinder plated with the wear resistant Nikasil.I have a set | ||

To answer the comment YES Nikasil cylinders or similar cylinders were / are available for light aircraft engines. These engines are typicaly boxer layout with replacable cylinders, air cooled, pushrod low shaft speed, much like our Buells the engine is tuned for Torque and built for longevity. unlike our bikes they are all dual pluged( 2 magnetos) and have controlable from the cockpit mixture, and the ability to heat the incoming air to prevent carburetor icing.  | ||

The old Rotary engine aircraft used a Nikasil plated cylinder wall, so that the seals would have better contact.  |
