Overview
The Yamaha R25 is a sportbike in production from 2015 to 2026. The 2026 model uses a 249.6 cm³ liquid-cooled parallel-twin four-stroke engine producing 35 hp (26 kW) and 23.5 Nm of torque at 10,000 rpm; wet weight is 166 kg.
A 780 mm seat height gives the R25 a relatively low seat position, while its 166 kg wet weight is something to account for when maneuvering at low speed. The wet, assist-and-slipper clutch can help calm the rear wheel during hard downshifts, and the 14 L fuel tank sets the amount carried between stops. ABS is optional, and the chain final drive needs cleaning and adjustment.
