HOW TO REPROGRAM YOUR KX450F FUEL INJECTION SYSTEM IN 17 EASY STEPS:

In adddition to the $500 calibration kit, you willneed a 12 volt battery and laptop PC. Human beings, especially motocross racers, are habitual tinkerers. We don?t know the meaning of the phrase ?leave well enough alone,? because in motocross you can always make improvements. Common understanding is that fuel injection will reduce the amount of motocross tinkering. It is true that fuel injection is self-regulating, but it also offers an increased potential for adjustment. How so? Its sensors allow adjus…

WE RIDE A KAWASAKI KX450F BUILT FOR THE AMA NATIONALS:

The MXA wrecking crew has a soft spot in our hearts for underdogs. To show our support for those who are not given a chance to show their might on a factory machine, we devised a plan. Instead of $500,000 salaries, $100,000 per race bonuses and airline tickets to every race, we decided to take an alternate route. A few months ago, we decided to build a bike that would allow us to race the AMA 450 Nationals on a shoestring. Our goal was to build a purpose-built motocross bike; one that would be competiti…

THE BEST USED BIKES! WHICH 450’s TO KEEP FOR ANOTHER SEASON? Which Used Bikes To Save And Which Ones To Jettison; We Name Names

CAN MY OLD 450 MAKE IT ANOTHER SEASON OR TWO? THE MONEY YOU SAVE CAN FINANCE YOUR RACING CAREER    Let’s take it for granted that your trusty, but rusty, old bike isn’t leaking fluid out of the shock, making clunking noises at low rpm, suffering from terminal rust behind the ignition cover, cracking down the head tube like old concrete or oozing tranny oil that looks more like chocolate milk than 30 weight. If your bike is sound and air worthy, your next questions should be:  …

10 BEST MODS FOR THE 2009 KAWASAKI KX450F:

WHAT IS THE BEST TRIPLE CLAMP OFFSET?    Most MXA test riders are universal in their endorsement of 22mm triple clamps on their KX-Fs. Why? Because Kawasaki’s geometry has a tendency to tuck and push. Pulling the stock 23.5mm offset back (24.5 on 2006-07 models) increases trail, which helps the front tire track more accurately through the center-out. You will need to slide the forks up in the clamps to get the most out of the 22mm offset clamps. CAN YOU FIX THE KX450F WITH A SHOCK LINKAGE? &nb…

First Ride: 2009 Kawasaki KX450F

By John Basher With all of the buzz circling around the 2009 Honda CRF450, it seems that many people forgot about the new Kawasaki KX450F. If you fall in that category, then shame on you! Kawasaki went whole hog on their 450 for 2009, utilizing electronic fuel injection, a new frame, different suspension settings, and even new styling. It is easy to understand that this is the biggest change that the KX450F has received since its inception in 2006. To introduce the bike, Kawasaki rolled out the red carp…

2008 RACE TEST KAWASAKI KX450F

  If there is a cause celebre for the 2008 motorcycle manufacturers, it is the total focus on making the new engines easier to use, more controllable and smoother. Kawasaki has joined the parade. They gave up the horsepower advantage they had in 2007 to go for a broad, mellow and less violent power delivery. While engine management issues got the most attention in Japan this year, there was a secondary issue?frame flex. And we aren?t talking about eliminating frame flex, but feeding it back into th…

MXA’S 2006 KAWASAKI KX450F TEST

One of the inherent problems with jumping on the bandwagon last is that almost everything that could be done has been done. The 450cc four-stroke technological hay wagon was almost around the bend before Kawasaki leapt on board. It’s been eight years since Yamaha single-handedly invented the modern four-stroke motocross bike in 1998. KTM got there five years ago, Honda four years ago, and Suzuki last year. Kawasaki is late to the party.   The downside of being last is that there are very few techni…
