The Honda CRF250R was an off-road motorcycle manufactured in 2004, following the introduction of the first motorcycle in the line, the Honda CRF450R. It was the four-stroke version of Honda's quarter-liter motocross machine.
In 2007, the Japanese motorcycle maker released the Honda CRF250R, an off-road motorcycle in the same shape and form as the previous one, with several modifications for better performance.
The 2007 machine lost some weight and had several revisions, such as retooled cam profiles, a revised brake lever linkage for better-stopping power, and an upgraded clutch system for better shifting.
For power, the 2007 Honda CRF250R had a 249cc four-stroke liquid-cooled single-cylinder engine underneath the fuel tank, managed by a 40 mm flat-side Keihin carburetor. The powerhouse was coupled to a five-speed manual transmission linked to the rear via a final chain drive.
The bike's riding characteristics were offered by a 47 mm inverted Showa cartridge-type adjustable fork on the front with 315 mm wheel travel and a Pro-Link swingarm tied to an adjustable Showa shock absorber on the rear with 315 mm of travel.
As for the braking power, the motorcycle packed a single 240 mm disc on the front clamped by a two-piston caliper and a 240 mm brake rotor on the rear tied to a hydraulic caliper, providing excellent braking performance.
