At the heart of the 2021 Yamaha MT-09 SP naked motorcycle, Yamaha pairs a 890 cc (54.3 cu in) liquid-cooled in-line three, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 78.0 x 62.1 mm (3.1 x 2.4 inches) with a 11.5:1 compression ratio.
On the scales, the MT-09 SP measures 190.1 kg (419 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 826 mm (32.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,430 mm (56.3 in) wheelbase engineered for balanced agility and highway composure. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 4.8 L/100 km provides an estimated theoretical range of roughly 292 km (181 miles) between fill-ups.
Within MotoLibrary's Yamaha archive, this model family spans 6 indexed model years from 2018 to 2025, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
