The Honda CRF450R was a racing motocross motorcycle powered by a 450cc four-stroke engine. It debuted in 2002 to replace the Honda CR250R and has been manufactured for over six generations.

The 2017 model year featured a new engine design, an air-assisted fork replaced by a Showa coil spring unit, and an optional electric start. The 2018 model year featured an electric start as standard equipment and a new engine mount that offered better chassis flex. The 2019 model year featured a new swingarm and a launch control setting.
The suspension system comprised a 49 mm inverted adjustable Showa telescopic fork on the front with 304 mm of travel and a Pro-Link swingarm with an adjustable Showa shock on the rear with 312 mm of travel.
Visually, the motorcycle packed standard fittings like a high-mounted dual exhaust system, a single seat, a high-mounted front fender, an aluminum frame, a dual-sided aluminum swingarm, and wire-spoke wheels with off-road tires.
