Second generation: (2014–2018)
editIn 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 motorbike safety regulations, ABS on motorcycles was required on all new motorbikes in the EU from 2017. This may cause minor differences in weight, electric or other specifications.

There is a small 2021 update, that adds a vapor canister to the fuel system, presumably to help the bike comply with the more strict Euro 5 emission standard.
