First introduced in 2004, the Honda CBR125R was a single-cylinder motorcycle made by the Japanese motorcycle manufacturer to fill the gap left by the discontinued NSR125. The bike was powered by a single-cylinder engine that featured a carburetor in the fuel system, while all the models manufactured from 2004 to 2006 resembled the CBR600F4i.
The 2005 Honda CBR125R came with the same power specifications and characteristics as the 2004 model, except for the Repsol color scheme that was introduced in 2005 and was available only on the CBR125RS5/6 models.
The bike came on a narrow and lightweight double cradle steel frame with a 31 mm telescopic fork on the front and a direct monoshock on the rear that provided optimum suspension, but also came with super-skinny tires that measured 80 mm width on the front and 100 mm on the rear.
As for braking performance, the bike packed a single 276 mm disc with a double-piston caliper on the front and a 220 mm disc squeezed by a single-piston caliper on the rear wheel that provided strong stopping power.
As for power, the 2005 Honda CBR125R was powered by a 124cc four-stroke single-cylinder liquid-cooled engine that delivered an output power of 14 hp with a peak at 10,000 rpm and 11 Nm (8 lb-ft) of torque available at 8,250 rpm.
With the help of a six-speed manual transmission and a dry weight of 127 kg (280 lbs), the bike was propelled to a top speed of 113 kph (70 mph).
