2025 Honda CRF450RX

Honda’s CRF450RX draws together motocross performance and off-road capability.

With only slight differences to its CRF450R cousin, including a larger fuel tank, 18-inch rear wheel, and kickstand, the RX brings a competitive edge to off-road racing.Honda

Overview

In only a handful of slight variations does the CRF450RX sets itself apart from Honda’s purebred motocrosser, the CRF450R, while retaining its sharp, aggressive performance. Created for competitive off-road racing in championships such as GNCC, WORCS, and NGPC, the slightly softer suspension settings and a less abrupt power delivery of the RX give it greater versatility on the trail. It features the same lightweight performance and advanced suspension components as Honda’s flagship MX dirt bike, but its 18-inch rear wheel and hand guards make it better suited to off-road conditions while the 2.1-gallon fuel tank and a kickstand make life easier on the trail.

The CRF450RX is still perfectly capable at the motocross track, making it an ideal choice for the motocross rider who also occasionally rides or races off-road. With the same chassis, engine, and suspension updates as its motocross relative, the CRF450R, the RX receives a heavy revision for 2025. The added off-road versatility of Honda’s elite 450cc package makes the CRF450RX an increasingly popular choice among riders looking for a do-it-all dirt bike for track and trail.
