10% is massive in a piece of metal rotating so quickly.
Tiny pistons is how some motorcycles got incredible power out of small displacement(and ridiculous gearboxes). 20,000 RPM engines, 150mph/240kmh out of 250cc(4-stroke as well). And this was in the 60's.

- Smoosh 6y ago> metal rotating so quickly *reciprocating It's also why racing engines (when not limited by regulations, or when only limited on total capacity) tended to have 8, 10, 12 or more cylinders. Despite the increase in the physical size of the engine, each cylinder would be smaller (for the same displacement) allowing higher revs and more power.
