Kawasaki’s 2009 KLX™450R may have inherited the lightweight engine and chassis from the multiple championship winning KX™450F motocrosser, but it is much more than a high-strung racer with a headlight and 18-inch rear wheel. Designed for the rigors of the off-road world, the KLX450R delivers a wide spread of power with high-traction torque and superior throttle control, combined with the enhanced durability, comfort, and long range that’s required in unforgiving off-road environments.

A simple push of the starter button is all that’s required to light off the 449cc four-stroke engine. In addition to push-button electric starting, the KLX rider also has the option of using the kick-starter. However, a high-capacity starter motor and compact, high-output battery helps ensure quick and reliable starts under just about any condition a rider might face.

A long lasting, trouble-free engine is the heart of any successful off-road racing platform. These extra durability traits were engineered into the KLX450R’s engine via steel exhaust valves and a reservoir tank equipped radiator to provide efficient cooling during long rides.
The KLX450R’s cam lift and timing, and beefy flywheel are designed to produce good low and mid-range performance. Harnessed to this engine is a wide-ratio five-speed transmission with gears specifically for the demands of off-road competition. The overall result is a gutsy response, ideal for hill climbing, mud holes, or other poor-traction challenge.

Avoiding rider fatigue, whether during a race, or a long weekend of back country exploration, was another top-priority for Kawasaki’s engineers. To minimize bothersome rider-taxing effects, the KLX450R’s nimble chassis utilizes top-of-the-line suspension components. Up front its Kayaba AOS inverted fork provides superb damping and more precise steering with tuning specifically optimized for light, easy handling characteristics. Oil and air are kept in separate chambers for sustained and stable damping performance during long events and low-friction seals for smooth fork action. Matching the fork is an equally capable Uni-Trak® rear suspension system. Its shock features both high-speed and low-speed compression damping with the suspension arm mounts below the swingarm for a longer rear suspension stroke.

Further enhancing rider comfort is a wider seat with slip-resistant top surface and smooth sides for enhanced mobility. The KLX450R’s 18-inch rear wheel is well suited to absorbing sharp-edged impacts and allows the rider to choose from a wide selection of off-road tires. Among the other off-road features are a two-piece, left-side cover that allows easy access to the air cleaner; engine guards for both sides of the engine; and a works-style aluminum skid plate.

A lightweight digital instrument cluster includes speedometer, dual tripmeter, odometer, and clock. The plastic fuel tank, which meets all environmental regulations, has a 2.1 gallon capacity and a reserve-enabled petcock. Lightweight illumination equipment includes a compact 35-watt headlight with a plastic lens to show the way to the podium and an ultra-compact and energy efficient LED taillight to highlight the part of the KLX450R that competitors are most-likely to see.

Authentic Kawasaki Accessories are available through Kawasaki dealers.

Review

When building their new 450 enduro weapon, Kawasaki took the proven path of using an established motocross model and then modifying it, thus ending up with a user-friendly, enduro/trail bike. It can often be a thankless task for the engineers too; faster riders want 'more motocross' while the average bush-basher prefers more trail bike influences.

There have been substantial changes made to the base-plant KX450F to turn it into the KLX450R but we'll just stick with the important stuff.

ENGINE

The KX450F motocross model has an awesome engine, (we've got one at our place, so we know) and it provides a proven base for the KLX450. The first thing that the Kawasaki engineers did when transforming the roaring MX donk for off-road riders was to keep the short-arsed crew happy by adding an electric starter (hooray for the little bloke!)

Next on the Important Stuff list was the addition of a wide ratio, five speed transmission. Getting a little more technical now, the flywheel mass (crankshaft) has been doubled, as in heavier, and this takes some of the edginess out of the motocross engine. The camshaft design and cam timing have also been modified in the interests of smoother power delivery and more torque.

One millimetre larger steel, exhaust valves are fitted, to enhance low end power and offer better durability. Regular stuff like an automatic cam chain tensioner, an auto compression release for the kick-starter and a four valve, double overhead camshaft head keep the KLX up to date with modern four-stroke engine design.

Of course the motocross muffler had to go. It's borderline offensive, even on a racetrack, and has been replaced with a trail friendly, re-packable, ADR compliant model. The motocross radiators have been retained although a reservoir tank has been added to absorb those boiling moments.

CHASSIS

The frame and running gear have the basic layout and look of the moto model but once again the enduro-friendly wand has been waved over it. Here are examples:
Fuel tank capacity has been increased to eight Litres , (the KXF is 7.2) and has a reserve position
The suspension settings have been tuned to be more off-road specific
The fork is a top-of-the-line, Kayaba AOS, jobbie, while the rear end uses the bottom link, Uni-Trak system
An 18-inch rear wheel and an 'O' ring chain will keep the enduro diehards happy
Our test bike came with Michelin tyres, although showroom models will have Bridgestone ED03s
The cockpit features Renthal '971' bend alloy 'bars, decked out with Aussie-made alloy Barkbusters and a digital speedo that'll tell you how fast you went, how long it took and how far you travelled
The air filter is accessed via a two-piece sidecover and is a 'no tools' job for servicing, as it should be on a trail bike
And if you were wondering how much did the appetite for ADR compliance and an electric leg cost in the weight deptartment when compared to the KX450F, according to Kawasaki about 10kg, although that sounds a little conservative to us

RIDE TIME
Two things become apparent when you crank up this bike. First the choke lever is almost impossible to operate unless you have the fingers of a five year-old. Second, the exhaust note is incredibly quiet. The decibels, or lack of them, coming from this bike can be confusing. The first couple of laps around our test track had me questioning why this bike could feel so responsive when it sounded like a choked lawn mower.

The front end would lift effortlessly over whoops and tree roots and the corner exit response was smooth and tractable, yet still fast. You really need to ride this bike a bit to get your head around the motor. It doesn't romp and stomp and it's not angry, but it does go pretty darn well. It's not a 'chunky' motor and it doesn't stall easily. You really don't need to use the clutch too much either, it's very electric.

We rode this bike in a variety of terrain too. You name it: fast swoopy stuff, tight gnarly hills, sand washes, fire trails, and we kept trying to find an excuse to need more power but couldn't come up with one. Vince Strang and I spent a fair bit of time playing with this bike and at the end of the day we both had to give the engine a thumbs up for trail riding, even if it did sound like a four-stroke lawnmower.

But, and there's always a but, the other side of the coin is that the KX450 has no anger or aggression in stock trim but a lot of people who purchase a 450 enduro bike expect some aggro for their dollars. I'm sure that in the next couple of months an aftermarket race pipe will surface for the KLX and it'll be interesting to see what effect that has on performance.

The chassis and suspension come straight from the motocross model and Kawasaki have done a particularly good job on setting the suspension up for off-road riding. Plush and smooth are two words that get thrown around the keyboard a lot when it comes to describing motorcycles, but in this case that's an appropriate description. We had testers weighing from 60 to a 100 kilos ride this bike, (no, not all at once) and yes, it was a big ask to expect that they'd all like the stock suspension setup, but they all said the ride was "plush and forgiving". To us that sounds a helluva lot like an endorsement.

Stopping performance was top shelf stuff too. The front brake had a nice positive feel at the lever and the bike didn't headshake coming down from speed. Stability and straight line tracking through rough sections wasn't a problem either, but tipping the bike into corners was a different matter. It's not that the KLX450 corners badly, it's just that it likes to stand up, even around corners, and it takes extra effort on the rider's part to arc a turn fluidly.

Some tuning in with the race sag and fork height could help here. The electric leg worked well every time but I'd hate to have to rely on it. Like all electric start, competition off-road bikes the battery just doesn't have enough guts for constant use, but it did start easily with the kicker and after a few kays the battery was juiced again anyway.

Crankcase and lower frame protection is something we'd look into if we owned one of these bikes, and at this stage the only sump guard we know of is the 'Hyde', imported by A1 Accessories. It's surprising how easy lower alloy frame rails can be damaged, so for that reason alone we'd fit an aftermarket guard.

SHOULD YOU BUY ONE?
As far as the trail rider goes, this bike is a buy it and ride it proposition. It has all the necessities for trail riding. The gearing's fine, the brakes work, the cockpit is all enduro and the engine could pull you smoothly and quietly up the southern face of Mt Kosciusko.

Racers and rev-heads will demand more from this bike though; they'll want more hit from the motor, and as a couple of our testers mentioned, they really did expect more action from a competition 450. We reckon a race pipe, and a little tuning would fix the mojo problem, but don't feel embarrassed if you just buy this bike and ride it stock. It goes a hell of a lot better than it sounds. RRP: $11,990 plus ORC.

The KLX450R's powerplant comes directly from our mighty KX450F motocrosser. To transform the liquid-cooled 449 cc KX450F power unit into an off-road racing winner, the highly acclaimed engine was tuned for maximum low- and mid-range performance. The result is a wide spread of responsive, high-traction torque and superior throttle control for low-speed maneuvering. The numerous modifications consider the variety of conditions riders face in open-course racing and also contribute enhanced durability and reliability to ensure that both man and machine reach the finish line.

Improved low and mid-range power characteristics for gutsy response when climbing hills, riding in the mud or in other poor-traction, low-speed conditions.

Flywheel mass is double that of the KX450F to provide ultra-smooth engine power characteristics.

Efforts were made to achieve the widest possible torque band, so that traction efficiency would be maximized for a greater part of the rev range.

The KLX450R's linear power curve features plenty of over-rev, giving riders ample latitude in choosing their shift intervals.

The functional design of the clutch lever assembly results in a straighter run for the clutch cable, offering smooth, low-effort operation. The clutch's excellent feel is especially welcome in the often tight and low-speed off-road racing environment.

Engine guards protect both sides of the engine (KX450F is right side only).

Works style aluminum skid plate completes the engine protection.

For efficient cooling during long enduros the radiator is fitted with a reservoir tank.

Lightweight, high-performance titanium intake valves ensure accurate valve timing even at maximum engine speed. Oxide membrane treatment resists wear.

Steel exhaust valves replace the KX's titanium units for improved durability.

Exhaust valve diameter is decreased by 1 mm for improved exhaust efficiency.

Aluminum valve spring retainers reduce reciprocating weight for reliable valve control at high-rpm.

Double valve springs also help ensure stable valve operation and allow a short cylinder head height.

Revised cam lift and timing boost low- and mid-range torque.

The camshaft lobes and tappet surfaces feature a soft-nitriding surface treatment for long wear and high-rpm reliability.

Quick-shifting, wide-ratio 5-speed transmission features ratios selected specially for off-road racing.

The transmission's gears are designed for high durability.

Digital, multi-map, AC-Capacitor Discharge Ignition uses the TPS signal and a 3D-ignition map to provide ideal ignition timing for various engine conditions. During acceleration and deceleration, the system makes adjustments to the 3D-ignition map, resulting in improved acceleration performance and smooth engine braking.

Accelerator Compensator circuit monitors changes in rpm and adjusts the ignition timing to prevent wheel spin and improve traction.

Lost spark control smooths the over-rev power by precisely cutting spark as the engine nears redline. Unlike conmventional systems, the KLX450R's spark gradually tapers off beginning approximately 1000 rpm before the rev limiter is reached so that power does not abruptly cut-out when the rev limiter is activated.

The multi-map ignition system features separate ignition maps for in gear operation and in neutral. In gear, the ignition timing raises idle speed in order to minimize the 4-stroke engine braking effect that can upset handling when entering corners. A neutral sensor engages a different timing map that reduces idle speed to a normal level which works in conjunction with the hot start lever to provide quick starting.

Phase-sensitive stator coil helps prevent kick-back during starting.

An electric starter was added. Having both electric and kick starters mean the bike can be quickly restarted if the engine stalls during an event.

High-capacity starter motor is compact, yet high-output ensures quick and reliable starts under all conditions.

The battery is located beneath the seat and behind the airbox.

Extra long headpipe ensures lots of low-down grunt in tight trails. The dual-weight centrifugal decompression system fitted to exhaust cam eases starting.

Keihin FCR 40 mm flat-slide carburetor is equipped with a Throttle Position Sensor (TPS) and an accelerator pump for quick throttle response.

New carburettor settings complement the engine changes.

The KLX450R is equipped with a hot start lever on the handlebar for easy starting when the engine is hot.

When the hot start lever is pulled, a small plunger at the front of the carburetor opens a passage that draws additional clean, unmixed air into the intake tract. The extra air leans out the fuel mixture to make starting a hot engine easier.

The airbox arrestor features a two-screen design. Space between the screens reduces resistance for improved intake efficiency.

The side covers share their design with the KX450F, although the holes have been eliminated to prevent the ingress of water.

The left-side cover features a two-piece construction with a special "door" that allows easy access to the air cleaner.

Torquey response in the low to mid-ranges is thanks in part to the all-new exhaust system.

Extra long headpipe ensures lots of low-down grunt in tight trails.

Large body muffler allows free exhaust flow for peak efficiency while keeping exhaust noise to respectable levels in multi-use parks.

U.S Forestry approved spark arrester ensures responsible riding.

Chassis

The KLX450R's slim aluminum perimeter frame - straight from the KX450F - is a composite structure comprising forged, extruded, and cast components.

The construction method for each frame component is chosen with consideration for weight and strength. This yields a very strong structure but of the lightest weight possible.

The frame's rigidity balance contributes to a package that is both quick-turning and light handling.

Like the KX450F, the frame widens at the ankles to offer the rider better grip and is narrower near the bend below the seat to allow a slim riding position.

The riding position is ideal for off-road racing.

The seat is wider than the KX450F's for comfort during long motos. The seat uses a slip-resistant top surface for good grip when seated and smooth sides for excellent rider mobility.

Two-piece radiator shroud design allows a hole where the shroud covers the upper frame spars, ensuring a narrow riding position at the knees. Compared to the KX shrouds, the KLX shroud design is optimized for a seated position.

The seat, tank and shrouds were designed to integrate perfectly, creating a single smooth surface for maximum rider mobility.

In order to ensure superb control and the best possible road-holding performance over a variety of terrain, suspension quality could not be compromised. The KLX450R shares the same top-of-the-line suspension as the championship-winning KX450F.

The Kayaba AOS (Air-Oil-Separate) inverted fork from the KX450F offers superb damping and steering precision. Where the KX settings maximize sprint and jumping performance, for the KLX, settings were chosen for light, easy handling characteristics. Oil and air are kept in separate chambers for stable damping performance during long motos.

Kayaba AOS (Air-Oil Separate) sealed cartridge inverted fork separates oil and air by using an internal damping cartridge within the fork similar to a shock absorber bladder. The sealed cartridge prevents the mixing of air and oil and provides consistent damping and improved adjustability.

The AOS cartridge resides in the upper portion of the fork with the fork spring underneath. As the fork compresses, a free-floating piston takes up the additional volume within the cartridge as fluid is displaced by the piston rod. A large hydraulic bottoming stop is located at the bottom of the cartridge and engages as the fork nears the end of its travel.


Compression damping adjustment is located on top of the fork while rebound damping adjustment on the bottom.

Low friction seals contribute to smooth fork action.

Fork is adjustable with 22 click compression damping screw at the fork cap and 20 click rebound damping screw at the fork bottom.

Front fork has long travel.

Low-friction fork seals contribute to smooth action.

The rear shock features dual compression damping adjustability, allowing high-speed and low-speed damping to be tuned separately. Shock compression damping is 22 click adjustable for low-speed while high-speed damping is 2-turns or more adjustable. Rebound damping features 22 click positions.

Rear spring is fully adjustable on its threaded collar.

The New Uni-Trak rear suspension system mounts the suspension arm below the swingarm, allowing a longer rear suspension stroke. The longer stroke in turn allows more precise rear suspension tuning.

Rear suspension action is initially soft, but becomes much firmer near full compression to prevent bottoming.

The alloy swingarm uses a cast front section, tapered hydroformed spars and forged chain pullers. The tapered shape of the spars allows clearance between the rear brake calliper and silencer when the rear suspension is fully compressed.

An 18" rear wheel (KX450F: 19") offers a wide selection of tires to choose from. High-traction Bridgestone MX tires are fitted.

Petal style brake discs front and rear help to reduce unsprung weight.

The wave shapes of the petal discs help clean the brake pads for more efficient braking performance.

Lightweight digital instrumentation includes a speedometer, twin tripmeter, odometer and clock.

Works-style Renthal aluminum handlebar (standard-type) saves 0.3 kg in weight.

Compact lighting package includes a 35 W headlight with lightweight plastic lens.

LED tail lamp is ultra-compact and energy efficient.

Lightweight plastic fuel tank has an 8 litre capacity (KX450F: 7.2 Litres ).

Fuel petcock is fitted with a reserve.

A side stand is fitted as standard equipment

KAWASAKI KLX 450 TOP SPEED - QUANTO DEU KM/H ???

Kawasaki’s 2008 KLX™450R will soon be making a name for itself amongst the growing legion of off-road racing fans. This purpose-built version of the brand’s World Supercross Championship winning four-stroke KX™450F motocrosser delivers the same high performance features as the KX model, yet modifies it for the improved durability, comfort, and range needed by off-road racers.

Adapted to the rigors of grueling courses, this model’s lightweight engine has been tweaked for more low and mid-range performance delivering a wide spread of responsive, high-traction torque and superior throttle control for low-speed maneuvering. The KLX450R’s gutsy response to hill climbing, mud holes, or other poor-traction, low-speed conditions will put it at the top of every racer’s “want” list.


Kawasaki engineers have combined revisions in cam lift and timing in order to boost low and mid-range torque. Adding to the special characteristics of this engine are a heavier flywheel with double the mass of the KX450F’s unit and a wide-ratio five-speed transmission with gears that have been specifically selected for off-road competition.

Adding an electric starter in addition to its kick-starting capability gives the KLX rider more options in the event of a stall. A high-capacity starter motor and compact, high-output battery helps insure quick and reliable starts under virtually all conditions a racer might face. A simple push of the starter button is all that’s required in the event of a stall and can often be accomplished while still moving.
