History

The CBR125R was introduced in 2004 by Honda to fill in a gap in the 125 cc market left by the discontinued NSR125. It is powered by a 124.7 cc (7.61 cu in) liquid-cooled 4-stroke 2-valve SOHC single-cylinder engine with a claimed power output of 10 kW (13.4 hp; 13.6 PS).^[1]

2004–2006

2006 Honda CBR125R

The models produced during these years resemble the CBR600F4i and used a carburettor in the fuel system. The Repsol color scheme was introduced in 2005 and remained for the following year only as the CBR125RS5/6.^[2]

2007–2010

2008 Honda CBR125R

In 2007, the CBR125R received some major changes. This model got different front fairings to resemble the look of the CBR600RR as well as colour changes to the swingarm and front telescopic fork which are now black. Engine changes included the implementation of PGM-FI fuel injection system, IACV (Idle Air Control Valve) which operates alongside the PGM-FI, and HECS3 oxygen sensor to comply with EURO3 standards.

2011–2016

2011 Honda CBR125R

In 2011, the CBR125R received the first major overhaul since its inception, bringing its looks in line with the 2011 CBR250R, which in turn borrows from VFR1200F sports tourer.^[2]
