The CRF450R is built to win and shot through with MXGP championship owning DNA. Its development has gone hand in hand with racing success, and the new CRF450R draws on all the lessons fought in the heat of battle to make going fast – really fast – easier especially on a rough racetrack.
It’s the lightweight, quick-steering tool it’s always been but a new rigidity balance for the aluminium twin-spar frame ups high-speed stability in tough conditions, with completely new Showa™ suspension front and rear raising the game in terms of control and traction. And the awesome engine matches the chassis upgrade with more power, and even more precise throttle connection that delivers relentless, race-winning drive.
DISCLAIMER Images shown are a mixture of the current and previous year model.
So you can drive harder than ever, the engine is armed with narrower intake ports, a longer air funnel and smaller, 44mm diameter throttle body delivering higher-velocity air flow to create more torque and low-down power. New ECU settings and valve timing (straight from Tim Gajser’s #243 HRC machine) create a usable powerplant with Launch Control, HSTC and EMSB to put it completely at your command.
We never, ever stop pushing. That’s what it takes to fight at the front and the CRF450R is now easier to ride faster, for longer. Its lightweight aluminium frame features a new, factory-rider specification rigidity balance – from 2mm thicker front frame joints and upper shock mount – as well as new steel engine hangers producing a stable chassis that finds amazing front-end grip, yet steers razor-fast.
HRC riders – Gajser and Roczen – have led the suspension updates to produce faster lap times with less effort. Working with the new frame ‘tune’ the rear spring rate is higher at 56N/mm, with increased rebound/compression damping for incredible control over bumps and ruts. The 49mm USD forks also have new damping settings for optimum front/rear balance.
Minimal bodywork is easy to move around and remove. The CRF450R uses top-draw equipment; Renthal Fatbars offer comfort and four-way adjustment. The 6.3L fuel tank is made from titanium. Aluminium DID rims are light and strong, while a 30/27mm diameter two-piston front brake caliper ensures consistent stopping & power at racing temperatures.
Our first production motocross racer, the CR250M Elsinore, took to the track in 1973 and set us on our journey. The new CRF450R is built ready to race. .
A big year for development. The CR250M had earned its racing ‘R’ in the late ‘70s, and in 1981 Honda unleashed their factory-bike technology to the buying public with the first production, liquid-cooled machine.
Honda kicked off a new MX mission with its first generation of 450, the first four-stroke and a direct replacement for the CR250R. And with its 250-based chassis, it was slim and lightweight.
