I am pretty sure this doesn’t exist. It has in the spec 54.2 mm stroke. Well at 17,000 rpm the piston speed would be in excess of 6000fpm, WAY above an an acceptable reliable design. The rods wouldn’t be the issue, Honda built its oval piston motor back in the 80’s that spun well over 30,000 rpm the rods weren’t a problem. The piston speed is the real issue with the deign. Yea that motor in the above link, given the specs is a pipe dream.
