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. To comply with EU regulations, ABS is a standard equipment on all bikes since 2017. This may cause minor differences in weight, electric or other specifications.
