The Honda CBR125R was a sports bike made by Honda in 2004, powered by a single-cylinder engine with the smallest displacement in the CBR series. The bike was manufactured to fill the gap in the 125cc market left by the discontinued NSR125 motorcycle.
The bikes manufactured between 2004 and 2006 were powered by a single-cylinder engine fed by a carburetor and resembled the CBR600F4i. Also, in 2005 Honda introduced the Repsol color scheme that was available only for the CBR125RS5/6 models.
In 2007, the CBR125R came in an updated package with redesigned front fairings that resembled the CBR600RR but also featured a black-finished swingarm and front fork. In the engine department, the maker introduced a new PGM-FI fuel injection system, an Idle Air Controle Valve (IACV), and a HECS3 oxygen sensor for EURO3 emission standards.
In 2011, the Honda CBR125R featured its first major revision since its first day of life, with changes to the looks that were brought in line with the 2011 CBR250R, which also borrowed its appearance from the VRF1200F sports tourer.
In 2012, the Japanese motorcycle manufacturer launched the CBR125R Repsol, a motorcycle that featured all the updates accumulated over the years and came in a Repsol Color scheme that enhanced its appearance.
The 2012 CBR125R Repsol motorcycle was powered by a 124cc four-stroke single-cylinder liquid-cooled engine that delivered an output power of 14 hp with maximum strength at 10,000 rpm and 11 Nm (8 lb-ft) of torque available at 8,250 rpm.
