HONDA CRF450X (2005-2006) Specs, Performance & Photos

The Honda CRF was a series of off-road, trail, and dual-sports motorcycles manufactured and marketed by Honda since 2000. The CRF line of motorcycles came to succeed the Honda CR series.

In 2005, the Japanese motorcycle maker introduced the Honda CRF450X, an off-road motorcycle powered by a 450cc liquid-cooled engine. The bike shared a few features with the CRF450R motocrosser and had an MSRP of $7,000.

The motorcycle had great success in the Baja 1000, an annual Mexican off-road motorsport competition, with 11 victories and five more in the Baja 500. It was manufactured over three generations, and since October 2018, 27.000 units have been sold.

The first generation included motorcycles manufactured from 2005 until 2007. It packed a wide-ratio transmission, an electric starter, and an 18-inch rear wheel.

Compared to the previous models, the second generation, comprised of models manufactured from 2008 until 2017, came with a steering damper, a revised accelerator pump, and a smaller fuel tank.

The third generation was made between 2019 and the present (2024) and featured a new design with several modifications, such as a fuel injection system and a CRF450R-based engine and chassis with more crank mass and a revised piston.

The 2005 Honda CRF450X had installed a 449cc four-stroke single-cylinder liquid-cooled engine at its core, fed by a 40 mm flat-side Keihin carburetor and assisted by a five-speed gearbox linked to the rear end via a final T-ring-sealed chain drive. The bike boasted 45 hp at 7,500 rpm and 43 Nm (32 lb-ft) torque at 7,000 rpm.
