High-tech 125cc engine with VVA system
The R125’s highly efficient engine is equipped with large intake and exhaust valves and a compact combustion chamber that provides impressive acceleration. And its high-tech Variable Valve Actuation (VVA) system optimises the valve position for strong low rpm torque with high rpm power. The wide diameter throttle body gives a smooth and controllable throttle feel – and the sports exhaust system produces a sporty and emotive sound.
Icon Blue and Tech Black colours
The R125 shares the same race-bred DNA as every member of the iconic R-Series family. Now available in a new premium duo-tone Icon Blue colour with matte blue detailing – as well as a dynamic Tech Black option – this is surely the most impressive looking R125 ever.
Delivering smooth and light handling characteristics as well as excellent high-speed comfort, the R125 is one of the best-handling bikes in its category. Its Deltabox frame uses optimum front and rear geometry as well as a short aluminium swingarm and 41 mm upside down forks to give you the ultimate 125cc supersport chassis specification.
Lightweight aluminium swingarm
Yamaha R-Series models are designed to give you the ultimate in style, performance and technology. And to underline this, the R125 features a lightweight aluminium swingarm. Manufactured using Yamaha’s advanced casting technology, its short dimensions, low weight and optimised rigidity deliver sporty handling performance.
A&S (Assist & Slipper) clutch
To help you take full advantage of the free-revving engine performance, the R125 is equipped with an A&S clutch that gives a light feel at the lever for easy operation and precise control. This design ensures smooth and efficient acceleration, and during deceleration the A&S clutch improves controllability.
R-Series LED twin-eye body design
Inspired by the iconic R1, the confident and aggressively styled face of the R125 features dual LED headlights that reinforce the shared family DNA. And with the M1 MotoGP® style front fairing, LED taillight and premium finish emphasising the race-bred specification, there’s no mistaking that pure R-Series DNA runs through the R125’s stunning bodywork.
