2020 Yamaha YZF-R125 Totalmotorcycle.com Features and Benefits

Outstanding braking performance

Equipped with a large diameter 292mm front disc and a 230mm rear disc, the YZF-R125’s braking systems produce outstanding performance. Featuring state-of-the-art calipers and lightweight discs that deliver powerful and progressive stopping power, this sophisticated braking setup gives you precise and accurate control.


Excellent combustion efficiency

To achieve high levels of intake efficiency the YZF-R125 engine is equipped with large intake and exhaust valves as well as a compact combustion chamber. Combined with the high-tech VVA – as well as the large throttle body and sports exhaust system – this configuration produces impressive acceleration.


Sporty and comfortable riding position

Besides its race-bred YZR-M1 style cockpit, the YZF-R125 is also equipped with a 2-piece rider and passenger seat featuring thick foam for a smooth ride. With an optimised handlebar position and aluminum rear set footrests, the YZF-R125’s ergonomics give a balanced riding experience that’s both sporty and comfortable.


Wide 140-section rear tyre

To confirm its strong R-series DNA the YZF-R125 runs with a wide 140/70-17 rear tyre that gives excellent stability and confident cornering. Offering a good balance of grip and durability, this supersport style tyre is designed to enable you to optimise the potential of the engine’s wide spread of power, and its wide-section accentuates the bike’s aggressive R-series stance.


A&S (Assist & Slipper) clutch

To help you take full advantage of the free-revving engine performance, the YZF-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 helps to prevent rear wheel lock ups.


R-series LED twin-eye body design

Inspired by the iconic YZF-R1, the confident and aggressively styled face features dual LED headlights that reinforce the shared family DNA. Its M1 MotoGP style front fairing underlines the race-bred specification, and with a 12 LED taillight and premium finish, there’s no mistaking the pure R-series DNA in the YZF-R125’s stunning bodywork.


Deltabox frame

Delivering smooth and light handling characteristics as well as excellent high speed comfort, the YZF-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 aluminum swingarm and 41mm upside down forks to give you the ultimate 125 supersport chassis specification.


Lightweight aluminum swingarm

Yamaha R-series models are designed to give you the ultimate in style, performance and technology, and to underline its position as the premium 125 supersport, the YZF-R125 features a lightweight aluminum swingarm. Manufactured using Yamaha’s advanced casting technology, its short dimensions, low weight and optimised rigidity deliver sporty handling performance.


11-litre fuel tank

The YZF-R125’s aggressive race-bred bodywork is complemented by a sleek fuel tank that emphasises the bike’s pure supersport pedigree. Consisting of a steel inner tank protected by lightweight close-fitting external covers with a high quality finish, the 11-litre tank can be easily removed for routine maintenance.
