2009 Honda CRF450R - Photos & Specifications

Opinions the world over seem to be totally unanimous in their impressions of Honda’s new CRF450R. Absolutely brilliant and quite simply the best crosser in it’s class!

The new innovative exhaust system has helped to improve weight distribution, effectively centralising it. This, combined with the redesigned frame, low rotational mass, weight, as well as the low centre of gravity results in a bike that is so much more responsive. For those who think it will be easy to manoeuvre on the ground, just wait until you try it in the air! According to those who have ridden it, it requires much less in the way of body movement to turn it in the air.

The smooth fuel injected engine is super crisp and responsive at low revs and at high revs almost goes into hyper-drive. The power is delivered just when you want it and it almost feels as if your right hand is talking directly to the back wheel. When you shout at it, it just gets up and goes just like it should do. Leaving others trailing in your wake!

The new system has an indicator integrated into the engines stop switch that shows the rider the pre-race conditions for the FI system. Perfect for racers and this concept is a first in motocross bikes. A new settings kit, developed by HRC using technology gained their many years of racing, gives the rider the ability to program the system. Using precise data, the bike can be set up to so that it performs at it’s best under all race conditions.

The bike has a slimmer overall feel to it and almost feels as if it is getting to the point where it is getting too slim, but this more than helps with the feeling that it is ridiculously easy to manoeuvre around. The newly designed rear frame gives easy underseat access to the air filter, while large air ducts, situated in the side covers, allow for a significant airflow in the mid to upper rev ranges. The new 48mm forks have had the outer tubes treated with Kashmira coating so that friction is reduced and offer 16-step rebound, as well as 18-step compression damping adjustments. The new rear damper, with its 320mm wheel travel, is fully adjustable and offers 20 step rebound damping.

Front braking is provided by lightweight, dual piston callipers on 240mm discs, while at the rear a HRC works-type system provides strong braking capabilities.

KEY FEATURES

New lightweight, battery-less fuel injection/ignition system delivers enhanced performance, a wider, higher power range and improved power delivery, as well as kick-start capability
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
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 motorcycles centre of gravity
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 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
New exhaust header design from the left side of the cylinder head exhaust port achieves optimal pipe length for the new fuel-injected engine
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

ENGINE
Powerful advanced 4-stroke 4-valve Unicam engine churns out 41.5kW of power at 8,500rpm and 50.3Nm of torque at 7,000rpm. Power is produced across a broader rpm-band for smoother, easier operation
Liquid-cooled 449cm Unicam engine pumps out nearly 92.4kW per litre while retaining its legendary simplicity and dependability
Innovative Unicam valve train provides both the lightweight of a compact single-cam drive and an optimum combustion chamber shape for maximum power at all engine speeds
Unicam valve train features a single carburised camshaft directly actuating two 36mm titanium intake valves
Lightweight titanium intake valves permit use of smaller valve springs and reduce overall engine height. Intake valve design has been revised for better mass centralization
Forged slipper piston is lighter than conventional designs, for quick-revving response while maintaining excellent cylinder sealing and high-rpm power
Lightweight Ni-SiC cylinder lining ensures cooler and quieter operation for extended engine life
Auto decompression and hot restart system make starting easy in all conditions
Twin-sump lubrication system separates oil supply to crankshaft, piston and valve train from clutch and transmission
New exhaust layout achieves lower weight and maximum mass centralisation
Gear-driven balancer reduces vibration while also driving the water pump
Eight-plate clutch provides ample surface area to handle the engines massive torque, while carefully matched clutch springs provide a light feel at the lever
Entire engine assembly weighs only 27.1kg, 1.8kg less than that powering the 2008 model

CHASSIS
Compact and slim chassis cross-section combines with new ergonomics for a smoother, easier ride. The area between seat and fuel tank is flat, and the fuel tank cap size reduced, making it easier for the rider to move along the seat
Front and rear wheels feature HRC Works-type aluminium spoke nipples for reduced unsprung weight
Front wheel features new stiffer axle collar, providing excellent rigidity
Rear axle wall thickness is reduced (from 2.5 to 2.2 mm) to save 38g of weight, while axle collar is strengthened for better rigidity
Large 50mm-diameter rear damper cushion provides consistent performance under demanding riding conditions
Compact dual-piston front brake calliper designed for lightweight
HRC Works-type rear brake system integrates the rear master cylinder and fluid reservoir, eliminating conventional external reservoir and hose
Link-type front brake master cylinder provides strong braking control in combination with a lightweight brake rotor

I'd be the same.. If I sat bolt upright on it I would have about 5 inches clearance between the bottom of my feet and the floor

I would love a crosser though, to go out and muck about in the dirt on..

Has anyone rode one? I wonder how much different or better it feels than an 08?

Re: 2009 Honda CRF450R - Photos & Specifications

I ride an 07 and a friend of mine has the 09, there is a difference for sure between the 2. The 09 seems to be a little easier to ride. The down side is after the 09 left the dealership it blew up about a half our later. Honda gave him a hard time about fixing it. So Honda decided to fix it and about another 15 minutes after that it blew up again . Honda then fixed it again and he has not had a problem since then. So I think i will keep my 07 for a couple more years to give Honda some time to work the kinks out. That whole situation just made me a little nervous about getting an 09. And yes I almost need a ladder to get onto my 07 but once your riding it you do not even remember how big it is.
