2001 KAWASAKI KX250

Refining a thoroughbred

When it comes to winning in the ultra-competitive 250cc class no manufacturer can afford to stand still. That’s why Kawasaki incorporates the latest of its continuously evolving, race-bred engineering into the 2001 KX250.  The KX250 has consistently been at or near the top of the magazine shoot-outs for the past several years and in 2000 its engine was unanimously rated “best in class.” For 2001 that engine gets even better with a boost in horsepower and improved shifting and clutch action, while the chassis has been fine-tuned to reduce weight and offer even better handling. 

Featuring one of the broadest powerbands in the class, Kawasaki focused on increasing the already-potent low-end power while improving response throughout the rev range and enhancing over-rev characteristics.  

The Electrofusion plated cylinder has revised porting. Narrower intake sub-ports increase intake velocity through the new carbon fiber reed valves to improve low-end and mid-range power. More peak power and over-rev capability has been obtained by flattening the top edge of the exhaust port to increase the effective port area. The stroke of the main Kawasaki Integrated Powervalve System (KIPS) valve has a shorter stroke so that it opens quicker to improve mid-range power. A new exhaust pipe and shorter muffler complement the cylinder porting to boost top-end performance. 

The power jet circuit in the 38mm Keihin carburetor now works with the Kawasaki Throttle Responsive Ignition Control (K-TRIC) system to alter the flow of fuel through the power jet according to engine speed and engine load as indicated by the throttle opening. Revised jetting more accurately meters fuel throughout the rev range for improved throttle response. 

For added engine durability the big end bearing cage of the connecting rod has a thicker silver plating and there is increased crowning on the crank pin. New, low-friction oil seals at the crank and sprocket shaft reduce mechanical losses and improve engine response. 

Shifting in the five-speed transmission is improved by utilizing narrower engagement dogs on the third and fourth gears and larger engagement slots on second and fifth gears. The third and fourth are also strengthened for increased durability. A larger diameter gear locating roller on the shift drum and increased spring load help give the rider a better shift feel.

The compact, high-tensile steel perimeter frame helps centralize mass and provide a longer, flatter seating position for precise handling. To reduce weight the mounts and bolts holding the fully-adjustable, bladder-type inverted cartridge fork were redesigned, and the aluminum steering stem is now tapered. A new front-brake master cylinder rests on the handlebars and operates the redesigned dual-piston brake caliper featuring larger pistons. New brake pads are fitted front and rear for quicker stops with less effort. 

Rear suspension is handled by Kawasaki’s highly acclaimed UNI-TRAK® linkage system that progressively increases damping and spring rates on the fully adjustable rear shock as the suspension is compressed. The shock has revised damping settings to match the new straight-rate spring, and the lower linkage bolts are now hollow to reduce weight. 

All Kawasaki KX motorcycles come with the support of Team Green™, Kawasaki’s amateur support program. Team Green attends more than 100 major events across the country, providing a network of regional support vehicles and highly-trained technicians who provide technical information and emergency parts assistance for anyone who rides a Kawasaki. Kawasaki also offers a comprehensive contingency program worth millions for amateur and pro riders who place well at designated events.

Team Kawasaki always races to win. With continually-evolving engineering straight from the racetrack and the unmatched support Team Green, the 2001 KX250 will once again be at the top of it's game.

2001 KAWASAKI KX125

New engine will help Kawasaki maintain winning heritage

After winning three straight American Motorcyclist Association (AMA) 125cc National Championships in the hands of Ricky Carmichael, the Kawasaki KX125 once again proved to be a winner when Shae Bentley rode it to the 2000 AMA 125cc Western Region Supercross title. And in an effort to maintain Kawasaki’s winning heritage in the highly competitive 125cc class the 2001 KX125 features major engine refinements and chassis changes.    

Engine performance rules the 125 class, and the 2001 KX125’s high-performance liquid cooled two-stroke powerplant has been reworked from top to bottom. A new cylinder head reshapes the combustion chamber to boost compression for harder-hitting power throughout the rev range. A new piston complements the reshaped head and now has closer tolerances to the Electrofusion-plated cylinder due to improved production methods. New cylinder porting is designed to improve low-end and over-rev performance characteristics while maintaining a smooth powerband.   

Fuel reaches the engine through a new Mikuni TMX 36mm carburetor that dramatically enhances low-end power and throttle response. The new carburetor puts the needle closer to the intake tract and a new float bowl shape allows the entire carburetor to be positioned closer to the crankshaft without interfering with the clutch actuating arm. The intake reed valve was moved 4mm closer to the engine and the new reed block uses a horizontal wing to stabilize intake flow at low revs. Reshaped crankcases increase primary compression, improve flow and contribute to the improved low-end power. Revised ignition timing ignites the fuel mixture.   

At the reshaped exhaust port the Kawasaki Integrated Powervalve System (KIPS) governor has heavier bearings, new bearing cups and stronger springs to prevent valve flutter. The KIPS valves, which vary exhaust port timing according to engine speed for a broader powerband, now open quicker for increased mid-range power. A shorter muffler reduces weight and enhances mid-range response, while larger diameter exhaust pipe O-rings improve sealing.   

A lighter flywheel complements the other engine changes for quicker engine response. Kawasaki also offers three other flywheels of various weight to fine-tune engine performance to track conditions and riding styles.   

Finishing off the engine improvements is a new shift drum holder that is similar to that used on the KX250 and improves shift feel.   

The compact, high-tensile steel perimeter frame helps centralize mass and provides a long, flat seating position for precise handling. To reduce weight the mounts and bolts holding the fully-adjustable, bladder-type inverted cartridge fork were redesigned, and the aluminum steering stem is now tapered. A new front-brake master cylinder rests on the handlebars and operates the redesigned dual-piston brake caliper featuring larger pistons.   

Rear suspension is handled by Kawasaki’s highly-acclaimed UNI-TRAK® linkage system that progressively increases damping and spring rates on the fully adjustable rear shock as the suspension is compressed.  The shock has revised damping settings to match the new straight-rate spring, and the lower linkage bolts are now hollow to reduce weight.   

All Kawasaki KX motorcycles come with the support of Team Green™, Kawasaki’s amateur support program. Team Green attends more than 100 major events across the country, providing a network of regional support vehicles and highly-trained technicians who provide technical information and emergency parts assistance for anyone who rides a Kawasaki. Kawasaki also offers a comprehensive contingency program worth millions for amateur and pro riders who place well at designated events.

With its thoroughly revised engine and updated suspension, the 2001 KX125 is ready to maintain Kawasaki’s winning heritage in the 125 class.

2001 KAWASAKI KX100

More power for mid-sized KX

For those who outgrow the Kawasaki KX85 but aren’t quite ready for a full-sized KX125, the Kawasaki KX100 steps up to fill the gap. Larger than the traditional 85cc minicycle, the KX100 gets its increased stature with the addition of larger wheels, minor chassis adjustments and increased displacement.   

In 2001 the KX100 gets increased power from a new carburetor and other engine modifications, plus better handling due to chassis changes.   

 The KX100 is powered by a liquid-cooled two-stroke engine very similar to the one found in the KX85, but displacement is increased from 85cc to 99cc with a larger bore. To increase power there’s a new 28mm carburetor that’s 2mm larger than the previous unit and has a crescent slide to position the needle closer to the intake ports. Ignition timing was changed to maximize the effects of the new carburetor. A larger air intake cutout on the airbox and larger diameter duct to the carburetor improves airflow while a new carbon fiber intake reed valve aids throttle response. A redesigned exhaust port and new exhaust pipe capped with a shorter, KX250-style muffler operate more efficiently for improved power.   

The KX100 has a high-tensile steel perimeter frame, just like larger-displacement KX bikes. A new gas tank puts the fuel load much lower in the frame to lower the center of gravity for improved handling. A new left-side shroud gives the KX100 an even closer resemblance to its larger KX siblings and helps cool the ignition and engine, while the single radiator is still fitted to the right side. Adjustable long-travel suspension at both ends smoothes the roughest motocross courses. The front brake master cylinder was changed to the same knocker-type as found on the KX125 and KX250 for better feel, while both brake discs are now mounted with shoulder bolts for easier maintenance.   

With increased power and improved handling, the 2001 Kawasaki KX100 offers the perfect platform for the transition from a minicycle to the KX125.

2001 KAWASAKI KX85

Increase in displacement

For years the Kawasaki KX80 has provided a competitive advantage for younger riders on their way up the motocross ladder. In 2001 this venerable mini moto machine becomes the KX85 with increased displacement and other engine changes that increase power more than 10 percent over the previous model. Plus new bodywork and styling bring the KX85 even closer in line with its full-sized KX125 and KX250 siblings. 

 Adding engine displacement to smaller engines is one of the best ways to boost output, so Kawasaki increased the bore of the Electrofusion-coated cylinder to bring total displacement to 84.9cc. The cylinder head was redesigned with a narrower squish band and added volume to slightly reduce compression and enhance top-end power. While the piston is now larger it is three grams lighter and offers increased lubrication for the wrist pin. 

 Power was also gained by fitting a new 28mm carburetor that’s 2mm larger than the previous unit and has a crescent-slide to position the needle closer to the intake ports. Ignition timing was changed to maximize the effects of the new carburetor. A larger air intake cutout on the airbox and larger diameter duct to the carburetor improves airflow while a new carbon fiber intake reed valve aids throttle response. A redesigned exhaust port, revised Kawasaki Integrated Powervalve System (KIPS) and new exhaust pipe capped with a shorter, KX250-style muffler operate more efficiently for improved power. 

Although horsepower has been significantly increased the KX85 retains its broad powerband to make it easier to control for riders of varying skill levels. 

The new engine is bolted into a high tensile steel perimeter frame, similar to the ones found on its big KX brothers. A new gas tank puts the fuel load much lower in the frame to lower the center of gravity for improved handling. A new left-side shroud gives the KX85 an even closer resemblance to its larger KX siblings and helps cool the ignition and engine, while the single radiator is still fitted to the right side. 

 Long-travel, adjustable suspension at both ends helps smooth out the roughest motocross courses. Damping settings are revised at both ends and there are stiffer springs in the 36mm inverted front fork to handle the quickened pace from the increased engine output. The front brake master cylinder was changed to the same knocker-type as found on the KX125 and KX250 for better feel, while both brake discs are now mounted with shoulder bolts for easier maintenance. 

For years the KX80 has powered the climb to stardom for many of today’s top professional riders. With the added performance of a larger engine, the 2001 KX85 stands ready to continue Kawasaki’s race-winning heritage and provide a solid foundation for those who aspire to motocross greatness.

2001 KAWASAKI KX65

For the serious mini racer     

Serious mini riders demand a lot from their machinery, and the Kawasaki KX65 delivers. This is a great mini-motocross machine for accomplished young riders to hone their skills before making the move to the larger displacement classes, and for 2001 Kawasaki enhanced the KX65’s winning potential with several chassis revisions to improve its performance on rough tracks. 

 At the heart of the KX65 is a liquid-cooled, high-performance two-stroke engine that has a 1.5mm larger bore than the KX60. A lightweight and strong piston resides in the Electrofusion-coated cylinder that is bolted directly to the crankcase like those on the larger KXs for increased durability. 

The cylinder is positioned to accommodate a centrally located exhaust port and “lowboy” design exhaust pipe. This allows the pipe to be tucked in further to prevent contact with the rider’s leg. 

To help make shifting the six-speed transmission quick, easy and smooth, the clutch actuating mechanism and the shift drum ride on needle bearings. The light clutch and shifting operation are ideal for youngsters moving up from smaller, clutchless machines.   

The engine rests in a redesigned semi-double cradle steel frame with thicker walled tubing on the main downtube and lower cradle, plus stronger motor mount brackets, for increased durability. A detachable left rear section eases suspension and airbox maintenance. Overall ride height is increased 15mm through changes to the suspension system.   

The rear suspension uses the bottom-link UNI-TRAK® system found on the larger KX models, which applies progressively stiffer damping and spring rates to the single rear shock as the suspension is compressed. A longer shock clevis and shortened pull rods in the UNI-TRAK linkage raise the rear end. The front fork has large stanchion tubes that are longer and placed further down in the triple clamps to raise the front end. Stiffer springs and damping settings are now utilized at both ends to improve handling on rough tracks.   

Lightweight aluminum rims reduce unsprung weight to help improve suspension action. Both wheels feature hydraulic disc brakes that not only provide great stopping power but require little maintenance and ease wheel removal.   

Rider maneuverability is enhanced by the tank, seat, and side covers that give the KX65 the slim, racy look of its larger siblings. The graphics match those of the other KX motocrossers to make the KX65 the best-looking mini on the track.

2001 KAWASAKI KX60

Starting Point for Future Motocross Champions 

For those who aspire to motocross greatness, the Kawasaki KX60 provides a perfect machine on which to start building essential motocross skills. This is the bike on which Team Chevy Trucks Kawasaki’s three-time AMA 125cc National Champion Ricky Carmichael began winning championships and it’s built with many of the features and all of the reliability of the larger KX models he rides today. 

With a seat height of 28 inches, the KX60 is tailored for smaller riders just entering the sport. The works-type seat extends far up the fuel tank so the rider can slide forward to reach the handlebars easily and get better front-wheel traction for aggressive cornering. 

The KX60 features a liquid-cooled 60cc two-stroke engine mated to a six-speed transmission through a manual clutch. Long-travel suspension smoothes the ride over today’s motocross courses.
