Built around Yamaha's enduro - offroad motorcycle platform, the 2021 Yamaha TTR125LWE relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 54.0 x 54.0 mm (2.1 x 2.1 inches) with a 10.0:1 compression ratio.
On the scales, the TTR125LWE measures 90 kg (198 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
