R stands for Race. And every motorcycle in the legendary R-Series family can trace its roots straight back to Yamaha’s winning MotoGP® and World Superbike machines. The radical new bodywork on the new R125 is inherited from the R1 and R7, giving this lightweight 125cc Supersport some serious big bike attitude. 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.
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 the new 5-inch TFT instruments with smartphone connectivity via Bluetooth® keep you informed, and in touch.
For strong performance at all speeds the 125cc EURO5 4-stroke engine is equipped with Yamaha’s power-boosting Variable Valve Actuation (VVA) technology – 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 Icon Blue and Tech Black, R125 has everything you need to connect into R/World.
