Yamaha YZF-R125

The Yamaha YZF-R125 is a sport motorcycle designed by Yamaha and manufactured by MBK Industrie since 2008. In 2023 the model is in its fourth generation.

First generation: (2008–2013)
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.

Specifications
Specifications for EU version.

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 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.

Specifications
These specifications come from the owner's manual of a 2017 model with ABS.

Third generation: (2019–2022)
The 2019 model has a new rear swingarm, changes to the frame and bodywork, a new engine with Variable Valve Actuation (VVA).

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.

Specifications
As per the owner's manual of the 2021 model.

Fourth generation: (2023–on)
The bike yet again received a slight overhaul for the 2023 model year. The changes include some minor tweaks to the suspension like a different caster angle at the front (it is now 26°), and a shorter swingarm travel at the rear (it is now 110 mm down from 114 mm). The front half of the bike has reworked fairings and a new 5” full color TFT dash with smartphone connectivity.
