Built around Yamaha's sport motorcycle platform, the 2023 Yamaha YZF-R15M pairs a 155 cc (9.5 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 58.0 x 58.7 mm (2.3 x 2.3 inches) with a 11.6:1 compression ratio.
On the scales, the YZF-R15M measures 140 kg (309 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 815 mm (32.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,345 mm (53 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
