Second generation: (2014 - 2018)
In 2014, Yamaha gave a facelift to the model, with a slightly tweaked fairing set, an upside-down front fork and a full LCD dashboard.
The model launched without ABS, but it became an option for 2015, and comes as a standard equipment on all bikes since 2017. This may cause minor differences in weight, electric or other specifications.
In 2016, the LCD instrument received a minor revision, in which the segment arrangement for various gauges has been slightly modified, including a horizontal tacho instead of a vertical one.
