Built around Yamaha's sport motorcycle platform, the 2021 Yamaha YZF-R7 features a 689 cc (42 cu in) liquid-cooled twin, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 80.0 x 68.6 mm (3.1 x 2.7 inches) with a 11.5:1 compression ratio.
On the scales, the YZF-R7 measures 187.8 kg (414 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 850 mm (33.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,375 mm (54.1 in) wheelbase engineered for quick, flickable steering geometry. The 17-liter (4.5 US gal) fuel tank paired with a rated consumption of 4.06 L/100 km provides an estimated theoretical range of roughly 419 km (260 miles) between fill-ups.
Within MotoLibrary's Yamaha archive, this model family spans 9 indexed model years from 1999 to 2025, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
