All-new motocross model officially confirmed by Honda.
The 2017 Honda CRF450R – it looks different, feels different and delivers a whole new rider experience. In plain and simple terms it’s faster, much faster.
The CRF450R has defined the art of balance, with an engine that produces hard-hitting usable power in a race-ready package since 2002. It’s always been a machine that offers total control, together with the durability and longevity that Honda is long famed for.
The 2017 model is re-imagined, it’s the first ‘from the ground-up’ redesign of the CRF450R for eight years and packs a powered-up HRC designed engine with an 11 percent overall power boost and stronger torque right through the rev range.
It gets an all-new seventh generation aluminium frame with new chassis geometry, lower centre of gravity and a titanium fuel tank making it lighter and more compact.
The new CRF450R is fitted with factory driven 49mm Showa USD coil spring front forks, developed from a version supplied to MX race teams. They are everything one would expect from effectively race-spec suspension, the out of the crate fork action is supple, smooth and fully in control.
For the very first time, an electric-start kit is available on the CRF450R. Kit specification and local availability will be announced later.
The body is more compact with aerodynamically-efficient plastics with feature film insert graphics for optimum scratch resistance and a bolder effect.
Direct input from Honda’s MX GP and AMA teams highlighted the need to develop a race partner with the unoquivical need to be first out of the gate, first into turn one and to punch out a blistering lap time.
Honda have taken this literally with the design inspiration completely underpinned by creating a machine that is the ‘Absolute Holeshot.’
The central focus has been placed on ‘producing a new model with execptional engine performance, engine power, low centre of gravity and to offer outstanding rear wheel traction’ all in the one package.
It’s a lot to take in, a complete redesign and geometric rework that’s resulted in a stronger, lighter, sharper, faster machine.
Engine/Drivetrain key features:
– Downdraft intake layout increases power by reducing resistance, improving air-charging efficiency.
– New combustion chamber with higher compression ratio, decreased valve angle for greater efficiency.
– Use of finger rocker arm allows increased valve lift while retaining compact Unicam layout.
– Coils on valve springs have oval cross-sections to allow low engine height.
– New port layout with straighter flow for increased efficiency.
– New piston with improved combustion efficiency.
– Diamond-like carbon (DLC) on piston pin, rocker arm reduces friction, increases durability.
– New compact dual muffler with more-gradual pipe bends for smoother exhaust flow.
– Shallower clutch assembly with fewer, thicker plates for narrower engine width.
– Kick start standard, with electric start available as an accessory.
Chassis/Suspension key features:
– New layout allows improved traction through concentration of mass, lower center of gravity.
– Lighter sixth-generation aluminum twin-spar frame with revised geometry; allows improved cornering performance through reduction of torsional stiffness (lateral stiffness is unchanged).
– Lighter swingarm assembly with increased vertical and lateral stiffness.
– New rear-suspension location lowers center of gravity.
– Narrower cross section (down 30mm at radiator shrouds).
– Aluminum rear subframe with extruded gussets for lighter weight.
– Showa fork is now 49mm (up 1mm), with coil springs replacing air system.
– New lighter titanium fuel tank.
– The kill switch/ignition map adjustment switch has been combined into one unit for reduced weight.
– Dunlop Geomax MX3S tyres.
– Plastic bodywork with a smoother layout and have film-insert graphics for improved appearance and durability.
– The new front fender shape allows a more efficient air path to radiator.
