The Yamaha YZF-R125 is a sport motorcycle designed by Yamaha and manufactured by MBK Industrie since 2008. In 2020 the model was in its third generation.

First generation: (2008 - 2013)[edit]

In 2008, the bike initially came available as a four stroke replacement for the TZR125. Entering the thin market of small displacement 4-stroke sport bikes, it quickly gained traction and became a popular choice for young riders.

Second generation: (2014 - 2018)[edit]

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.

Third generation: (2019 - on)[edit]

The 2019 model has a new rear swingarm, changes to the frame and bodywork, a new engine with Variable Valve Actuation (VVA).[clarification needed]
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.
