Under the hood, the 2025 R25 is powered by a 249.55 cc, liquid-cooled, DOHC, inline twin-cylinder engine that complies with Euro 5+ emission standards. It delivers a maximum power output of 26.4 kW at 12,000 rpm and a peak torque of 22.6 Nm at 10,000 rpm. The engine is paired with a 6-speed manual transmission and features an Assist & Slipper Clutch, providing smoother gear shifts and reducing rear-wheel hop during aggressive downshifting. The motorcycle's design draws inspiration from Yamaha's flagship models, the YZF-R9 and R1GYTR, evident in its aggressive front fascia equipped with an M-shaped air intake duct and LED projector headlights. The fairing has been redesigned for improved aerodynamics, and ergonomic enhancements include a narrower seat and side covers, contributing to better rider comfort and control.

The seat height is set at 780 mm, and the motorcycle has a kerb weight of 166 kg. It rides on 17-inch wheels fitted with 110/70 front and 140/70 rear tubeless tires, and features a 14-liter fuel tank.
