The Honda CBR125R is a CBR series 125 cc (7.6 cu in) single-cylinder sport bike made by Honda. The CBR125R first appeared on the market in 2004. It is manufactured in Thailand by A.P. Honda alongside the similarly designed CBR150R, which is primarily aimed for the Far East market.

It has the smallest displacement engine of any CBR motorcycle.

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).

"A tidy little motorcycle with a reliable four stroke engine, safe handling and brakes"

The Honda CBR125R is an excellent ‘mid market’ 125. There are cheaper to buy / run bikes, like Honda’s own CG125 but they lack kudos. There’s a flotilla of fancy, mainly European motorcycles like Aprilia’s gorgeous RS125 but they’re silly money. But the Honda CBR125R's a tidy little motorcycle with a reliable four stroke engine, safe handling and brakes.

The Honda CBR125R is safe and easy – ideal for learners or lazy commuters. There’s no getting away from the Honda CBR125R’s tiny dimensions and very modest power output but you can push the Honda CBR125R hard and it doesn’t bite back. Brakes are ideal – progressive with enough power but not too much to catch out the unwary.

Liquid-cooled single cylinder four stroke engine works well in Honda CBR125R, producing 13bhp in a easy, useable manner. It should last well if the oil’s kept topped up (many won’t get that luxury). The Honda CBR125R gearbox is based on Honda’s off-road XR125 means the jump between first and second is rather large.

Model History

2004–2006

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

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

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.
