CRF450RX 2023
Honda’s ultimate cross-country machine evolves once more, thanks to HRC’s fight at the very front of a world-class pack; considerably more low-down torque and a smoother power delivery for the engine promote corner-exit drive, while revised frame rigidity and suspension allow greater stability on braking, quicker turning, elevated front tyre grip and improved ability on rutted ground. It’s a bike designed to make going faster, easier. New graphics feature a brand new redesign of the iconic HRC logos.
From £9,279.00
Introduction
For 17YM Honda introduced an all-new, competition-ready cross-country machine into its off-road line up – the CRF450RX. And it took as its rock-solid base the engine and chassis of the 17YM CRF450R – Honda’s first totally new 450cc motocrosser in eight years – with modifications including larger fuel tank,18-inch rear wheel, revised PGM-FI mapping and suspension changes.
The CRF450R was the perfect platform to expand on and gave the CRF450RX both the pure MX DNA to deal with any special stage and the confidence-inspiring competence to handle flat-out trails, challenging climbs and tight, tricky sections. And, just as importantly to an owner, it’s a high-quality machine built with the long-term Honda reliability that makes it easy to live with over years of use.
Development has mirrored the CRF450R, too. An HRC-developed cylinder head upped peak power and torque considerably in 19YM; HRC launch control was also added along with revised rigidity balance for the frame and swingarm, a new front brake caliper and adjustable-position Renthal Fatbar. For 20YM, just like its MX sibling, it received Honda Selectable Torque Control (HSTC).
21YM saw a major evolution for the CRF450RX. Starting from the exact same point as CRF450R – almost totally redesigned by HRC with advances taken directly from Tim Gajser’s 2019 MXGP championship-winning machine. 22YM bought ECU settings and suspension updates.
Now, for 23YM – underpinned by the factory rider feedback of the CRF450R – it follows the same direction of development; more low-down torque for the engine, matched to chassis changes that make going faster, easier for longer.
IModel Overview
Whether you’re a world-class racer, enthusiastic weekend campaigner or trail explorer, the easier it is to go fast, the faster you go. Since Tim Gajser’s 2019 MXGP championship win, the focus for the CRF450R has been around making everything – handling ability, power output and ergonomics – as rider-friendly as possible. And what’s good for the MX machine is equally important for the CRF450RX.
Newly revised rigidity for the frame allows an increase in rear damping force, for improved control, without unwanted stiffness. Likewise, front tyre grip is heightened and the 23YM machine (compared to the 22YM) is more stable and turns faster with better suspension reaction and bump absorption.
Driving the new chassis harder through and out of corners, the engine now produces much greater low-rpm torque with increased, smoother low-down power delivery; new intake ports, a longer air funnel, smaller diameter throttle body and revised, factory rider-spec. cam timing are responsible. The rear muffler has also been made more durable
