The meteoric rise of the invincible CRF450R has taken it to the highest realms of Supercross, motocross, desert, endurance, flat-track and Supermoto where it relentlessly punishes the competition time and time again. Constantly stepping up its game, the 2009 model is ready to dominate the battlefield once again with a new fuel injection system, more speed, more control, more reliability, more power and more performance. The only thing there’s less of is weight, making it the lightest and most manoeuvrable machine in its class!

Faster lap times

Testing on a sandy, supercross-style circuit revealed a lap time that’s a scorching 2 seconds faster than that delivered by the 2008 model. As well as that all-important weight reduction (a full 1.8 kg!), the engine has been re-engineered for easier riding, quicker response, better cornering and smoother power delivery. Every single component has been revised for the ultimate mass centralisation. Dimensions are changed for better traction out of the corners matched by faster acceleration. Even starting time is faster by 0.1 seconds from 0-10m, and 0.2 seconds from 0-50m.

Better jumping performance

The new CRF450R is slimmer, lighter and smoother, with a lower centre of gravity making control in the air easier. Aerodynamics have been honed for bullet-like projection through the air. Improved mass centralisation and lighter weight minimise inertia feel for a sensation of accomplished control and expert handling. Torque feeling is improved everywhere and overall performance is fast, slick and exhilarating.
This latest evolution is set to fly the CRF flag high at the pinnacle of motocross achievement, the peak of joy-giving aerobatic performance. Weekend warriors and factory pros alike - get ready to test your limits and bring even the toughest competition to its knees.

Honda CRF450R Features for 2009

• New lightweight, batteryless fuel injection/ignition system delivers enhanced performance, a wider, higher power range and improved power delivery, as well as kick-start capability.
• New fuel injection indicator integrated with engine stop switch shows pre-race conditions of the fuel injection system for Motocross racers. The concept of an indicator for a pre-ride check is a first for motocross. (Honda first!)
• New fuel injection system features automatic settings that deliver the same engine character and driveability in differing altitudes.
• Improved fuel consumption enables tank capacity to be decreased (by 1.5L), thus facilitating more weight savings.
• New cam link type decompressor reduces weight by integrating decompressor and camshaft.
• New thin-walled crank case casting reduces wall thickness to 2.0mm and achieves a weight reduction of 200g. (Honda first!)
• New plastic fuel pump module attached to bottom face of plastic fuel tank responds directly to fuel pressure and is placed to concentrate mass on motorcycle’s centre of gravity. (Honda first!)
• Rev limit increased 180 rpm.
• Large-diameter throttle body (50mm) delivers more power and enhanced performance across the entire range.
• Oil capacity decreased by 0.1 litres to allow for a lighter and more compact engine configuration.
• New HRC settings kit, developed from HRC’s long years of experience in racing technology, provides an easy-to-use programming system with precise data for setting up the machine to meet all race situations.
• Ignition timing and fuel mapping settings can be uploaded by connecting the motorcycle to a computer and following simple step-by-step instructions. The system radically simplifies the setup process and will make tuning accessible to a broader range of riders.
• New steering damper re-valved for more linear damping with new design front fork.
• New 5th generation frame is manufactured by casting rather than forging of two components, resulting in a weight reduction of 410g and increased lateral and torsional stiffness (4% lateral; 6% torsional) for optional strength and excellent response to rider input.
• New frame shape is slimmer overall with rounded lower parts providing 1mm more ground clearance.
• Revolutionary Ergonomics Design includes a more open and ‘easy’ ride position. Flatter seat to tank area allows the rider to move from front to rear more easily. New profile is also smoother and narrower from radiator shroud to air box to side panel, giving a smoother ride.
• New exhaust header design from the left side of the cylinder head exhaust port achieves optimal pipe length for the new fuel-injected engine. It also enables placement of the titanium muffler 115mm forward compared to the previous model, and contributes to mass centralisation.
• New, KYB rear damper and bigger (48mm) KYB front fork give better stroke feel, action & control for a plush overall feel and improved bump impact.
• New longer swingarm and new, wider rear tyre contribute better acceleration and traction.
• New design grips feature longer tapered cushions and deep pre-cut wire grooves for tighter, slip-free wire grip.
• New brake disc shape contributes 65g weight reduction (front 37g; rear 28g).
• New seat with newly textured side surface contributes to better grip.
  Improved clutch action gives smoother up and down shifting, decreases rider fatigue and increases control.
• New dimensions with centre of gravity moved lower and longer swingarm give good front traction feeling and improve acceleration.
• New plastic body parts with slim, aggressive styling allow rider to move easily and feature new Honda Racing inspired colours and graphics.
