The Honda NR750 had oval pistons. I thought I would share.

I can remember seeing views of the rotating assembly for this engine and it was amazing. Insanely expensive bike to buy and I reckon it would be hard to get parts for it. On the subject of odd pistons I can remember seeing pictures of a square piston engine. All sound like machining nightmares to me but I don't have CNC. Righto who is going to make one?
