2025 Yamaha Bws 125 Technical Analysis & Specification Breakdown

At the heart of the 2025 Yamaha Bws 125 motorcycle, Yamaha utilizes a 125 cc engine layout. Internal engine geometry specifies a 11.2 : 1 compression ratio.

On the scales, the Bws 125 measures 128 kg (282 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1 mm (0 in) wheelbase engineered for quick, flickable steering geometry.
