Engine power has been increased and refined to provide more grunt, particularly in the lower and middle rev ranges, and new suspension soaks up the bumps to help get the power to the ground on the roughest of motocross tracks. Numerous tweaks to the engine, chassis and running gear make the bike even more durable under race conditions.

 
Let�s take a look at the heart of the big Kawasaki first � the engine. A new piston and inlet cam have been introduced for 2013, and these, along with revised engine CPU settings and fuel injection mapping not only increase power and torque, but also distribute it more usefully across the rev range, with more emphasis on low to mid-range torque. The KX450F comes with three pre-programmed Digital Fuel Injection couplers that can be swapped in seconds to program the ECU for standard, hard or soft terrain. For those who need even more in the way of fine-tuning the three supplied map-sets can be re-programmed with a laptop via the optional Kawasaki KX FI Calibration Kit. The bike also comes with Kawasaki�s Launch Control similar to that fitted to the factory racers; the rider can activate it via a simple press of a handlebar button to allow full-throttle race starts in even the most treacherous of conditions. This it does by retarding ignition timing and eliminating wheelspin in the first two gears, thus improving traction and, as a result, acceleration. When the rider hooks third gear the system reverts to the pre-selected engine map for the conditions at the time. As with last year�s model and the latest KX250F, the 2013 KX450F uses a batteryless fuel injection system that harnesses power generated by the kickstarter to bring fuel and fire together for starting.
 
Although more power is always important, the biggest change to the KX450F for 2013 is in the handling, largely due to a switch to Kayaba�s revolutionary new pneumatic-spring forks. These replace the coil springs found in conventional front forks with pressurised air, saving weight and reducing friction as well as offering much easier adjustment over a far wider range of settings. The Uni-Trak rear suspension is also new for 2013, with linkage mounts below the swing arm for more precise fine-tuning. 
 
As with the KX250F, Kawasaki has widened the ankle area at the bottom of the lightweight aluminium perimeter frame to allow better grip and lowered the top of the fuel tank to make the new bike slimmer and easier to manoeuvre with the knees. The body panels are now smaller and the handgrips softer and longer, allowing the rider�s hands to be placed further inboard than on earlier models when necessary without sacrificing handlebar width. The handlebars are adjustable thanks to a top yoke that offers two sets of mounting slots and reversible posts that give the rider a choice of four positions to choose from � 25mm or 15 forward, standard, and 10mm towards the rear. Adjustable brackets also allow the footpegs to be adjusted upwards or downwards by 5mm, lowering or raising the centre of gravity as well as the rider�s point of view when standing. 
 
The brakes of the 2013 Kawasaki haven�t been neglected in the quest for race and championship wins. The front stopper uses a new master cylinder and 30mm longer hose to exert pressure more efficiently on the new high-friction pads and petal disc. The rear disc now mimics the front in having a petal design that saves weight and is largely self-cleaning in muddy conditions. 
 
The Kawasaki KX450F has always been an attractive racebike, but the 2013 model has undergone a number of changes that make it stand out even further from the crowd. The front mudguard and number plate are new and sharper looking, while the rear mudguard, as in the factory racers, is now white instead of green. The rims, also like those of the factory bikes, are now anodised in black while the forks and rear shock adjusters, oil cap and two plugs in the alternator have undergone the same process in blue. An embossed design on the clutch cover is intended to gradually become more prominent as the silver paint wears off due to contact with the rider�s boot.
 

Most people who buy motocross bikes are very competent riders who are competitive by nature, and this applies particularly to a fire-breathing earth-crunching Grand Prix based 450cc machine like the Kawasaki KX450F. The Kawasaki is designed to get these people onto the podium no matter what level of racing they compete in, from club racers to national championship contenders.
