Pretty cool but not new technology. I worked on opposed piston Fairbanks Morse ship engines for years. Granted they were antiquated dinosaurs and did not have oppposed cylinders. They fun started when you had to replace a crankshaft, the upper was easy but not the lower. These engines were a tad large for motorcycles ;)
I drove a 1960ish Comer truck with a similar engine style called a TS3 using a crankshaft with conrod out to rocker arm to conrod back in to pistons in a common bore below the crankshaft, at the time they made good power in a smallish space and were light but were VERY NOISEY indeed. Because they made 2 pistons move half the normal stroke they reved high for a truck diesel.
Maybe this motor with double the old way they can stand there ground or become dominant
