The F3’s extremely compact 12-valve three-cylinder motor with 120-degree crank and composite gear/chain camshaft drive does not have the radial valves of the F4 engine — there simply wasn’t the space available. The motor is more compact than the comparable Triumph 675 design and has its cylinders inclined more steeply forward.
