Manufactured to a best-in-class specification and featuring pure race-bred engine and chassis technology, the R125 is Yamaha's ultimate lightweight Supersport. With new graphics as well as a next generation Icon Blue, Tech Black and 70th Anniversary colour schemes that strengthens its R-Series family DNA, this lightweight 125cc Supersport has a serious big-bike attitude.
R-Connection
Featuring race-developed Supersport geometry, the Deltabox chassis is equipped with state-of-the-art 41mm KYB upside-down front forks and link-type rear suspension for super-agile handling. The footrest/seat/handlebar layout gives a sporty riding position for optimum control – and smartphone-connected 5-inch TFT instruments keep you informed – and in touch. And equipped with a powerful central LED headlight and dual LED position lights and M-shaped nose, its aggressive new face oozes pure R-Series DNA.
For strong performance at all speeds the 125cc 4-stroke engine is equipped with Yamaha’s power-boosting Variable Valve Actuation (VVA) technology and exhaust updates – and the traction control system and assist & slipper clutch enhance controllability when you’re accelerating and decelerating. With a premium finish available in a choice of next generation Icon Blue and Tech Black with new graphics or the stunning 70th Anniversary red and white, R125 has everything you need to connect to R/World.
Features
R1-inspired 5-inch TFT instruments
The R1-inspired 5-inch colour TFT instruments provide you with clear information and underline the R125's premium status and best-in-class specification. Select your ‘Street’ or ‘Track’ screen theme depending on the riding situation – and match the programmable shift light and rpm meter range easily in 200 rpm increments to your riding style and individual preferences.
Smartphone connectivity
It's easy to stay connected when you're riding the R125 by linking your smartphone to its TFT instruments using Bluetooth® and the MyRide app. Once connected, you'll have access to turn-by-turn navigation and destination weather conditions, plus incoming call and text message previews and music song and artist information on the 5-inch TFT screen.
R1-type handlebar crown and switches
Everything about the R125 is designed to give you the ultimate Supersport riding experience. Inspired by Yamaha’s MotoGP® bike, the racy cockpit features a high-quality R1-type handlebar crown – and the clip-on handlebars are equipped with an R1 replica right switch cluster.
R7-inspired LED headlights and position lights
The powerful and compact central LED headlight located in the centre of the M1 MotoGP® style nose underlines the R125's big bike attitude. Together with the R7-style LED position lights this aggressive face oozes pure R-Series DNA.
Dynamic next generation Yamaha Racing design
Inspired by Yamaha’s winning race machines, the R125’s next generation aerodynamic bodywork gives this lightweight Supersport a commanding big bike look and feel. Its aggressive R-Series face features an M-shaped nose inspired by the M1 MotoGP® bike to underline its racing heritage – and the next-generation Icon Blue, 70th Anniversary and continued Tech Black colours with dynamic graphics highlight the bike’s premium finish.
Traction control system
The R125’s traction control system gives you a high degree of controllability during hard acceleration by reducing driving force to the rear wheel, if any tendency to slip is detected. The premium and high specification also includes an Assist & Slipper clutch for controlled deceleration. And the R125 is also pre-wired for the fitment of an optional quick shift system for seamless upshifts.
70th Anniversary Yamaha Racing colours
Marking 70 years of Yamaha performance, the R125 wears its heritage proudly in a stunning white-and-red anniversary livery. Inspired by icons of the ‘90s, it’s a head-turning mix of nostalgia, attitude and absolute iconic Yamaha design – proof that legends never really go out of style.
