The Yamaha FZ/MT07   (called FZ–07 in North America until 2017) is a MT series standard motorcycle or UJM with a 689 cc (42.0 cu in) liquid-cooled 4-stroke 8-valve DOHC parallel-twin engine with crossplane crankshaft, manufactured by Yamaha Motor Company from 2014 and US release in 2015.

The Yamaha FZ/MT07 parallel-twin engine has a 270° crankshaft, whose two cylinders in the engine fire at an irregular interval. This format helps to harmonize the inertia forces inside the engine, resulting in a more responsive and “torquey” sensation for the rider, a feeling not unlike that of a V-Twin
