History and Evolution

The Yamaha YBR 125 has carved a niche for itself in the lightweight motorcycle class since its introduction in 2005. Replacing the Yamaha SR125, the YBR 125 came in different variants including naked, faired, and ‘custom’, powered by a 124 cc single-cylinder, air-cooled, four-stroke engine. Initially, carburetors fed the engine, but from 2008 onwards, fuel injection was adopted improving efficiency and emissions​​.

Throughout its lifetime, the model saw a few significant changes. Around 2010, a dual sport variant named Yamaha YBR 125 G was launched, featuring off-road enhancements such as engine and hand guards, a raised front fender, anti-collision fender for the headlight, and new block pattern tyres for better grip on unpaved surfaces​​.

The YBR 125’s design codes were carried through to its successor, the Yamaha YS125, introduced in 2017. Although primarily a facelift to meet Euro4 emission standards, Yamaha made several tweaks to the YBR 125 blueprint. Among the changes were a revised cylinder stroke, slightly increased power and fuel economy, and a raised seating position by 15mm, all while retaining the YBR 125’s visual identity​​.

The model history of the YBR 125 also saw some minor changes in its naming and coding for different markets from 2005 to 2008​. The YBR 125’s journey from 2005 to its culmination in 2016, followed by the transition to YS125, depicts Yamaha’s commitment to evolving with market demands and regulatory standards, while preserving the core attributes that made the YBR 125 a reliable choice among 125cc motorbikes.

The engine’s power delivery is smooth and predictable, making it a great bike to build confidence on.
