Modifications for 2004:

Next step, a good start for the youngster wanting to start in motocross. The Kawasaki KX60 is the smallest true motocross bike Kawasaki build and just the right size for a future champion to learn to ride on.

KAWASAKI KX60 Features and Benefits

• A strong rider friendly power plant, liquid-cooled just like the professionals use.

• An engine producing good power and torque at all rpm.

• 6-Speed Transmission

• High Tensile Steel Frame

• Uni-Trak Rear Suspension

• Nitrogen-Charged Shock

• Works-Type Seat, makes it easy to shift your weight forward for more front wheel bite in the turns.

The Kawasaki KX65 is the smallest KX and is built for experienced young racers as well as youngsters who want to improve their riding skills before advancing to a larger-displacement model. A liquid-cooled, high-performance two-stroke engine powers the KX65 and features a strong, lightweight piston residing in an Electro fusion-coated cylinder.

The KX65 has a quick and smooth-shifting six-speed transmission with a manual clutch-actuating mechanism.  The KX65 engine rests in a semi-double-cradle steel frame with reinforced tubing on the upper-main and rear-down tubes. And like its larger-displacement siblings, the KX65’s swing arm uses the bottom-link UNI-TRAK® system, which applies progressively stiffer damping and spring rates to the single rear shock as the suspension is compressed. The shock and fork boast four-way adjustable rebound damping for optimal handling.  Lightweight aluminium 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 simplify wheel removal.  The slim tank, seat and side covers contribute to the KX65 motorcycle’s sleek, racy appearance and enhance rider manoeuvrability. It also sports the unmistakable Kawasaki Lime Green plastic and graphics as the larger KX motorcycles.

Many of the world's top riders got their start riding Kawasaki KX80 Junior Motocross machines. The KX80's were incredibly successful winning Junior championships all over the world. The KX85 replaced the KX80 (in 2001) and is more powerful and even more competitive than the 80. So if your aim is to be a future champion Kawasaki's KX85 is the bike for you. There are two models, KX85 and KX85-II, the difference are the wheels the KX85 have 17in front and 14 in. rear wheel, the KX85-II (also called Big wheel) have 19 in. front and 16 in. rear wheel. When you outgrow the normal Junior motocross bikes but you are not yet ready for a 125, Kawasaki has the solution. Go for the KX85-II, bigger diameter wheels mean a higher seat and more ground clearance and an easier bike to handle when the standard size bikes have become too small.

The KX85 provides plenty of power, thanks to its liquid-cooled, two-stroke, single-cylinder 84cc engine. It’s equipped with high-tech features, such as an Electro fusion-coated cylinder with a narrow squish band and large volume to enhance top-end power. Fuel delivery for the engine is provided by a 28mm carburettor that features a crescent-slide to position the needle closer to the intake ports. A Kawasaki Integrated Power-valve System (KIPS®) and exhaust pipe capped with a KX250-style muffler complement the KX85.s tractable power band, which is easy to control for riders of varying skill levels. A smooth-shifting six-speed transmission. The KX85 utilizes a high-tensile steel perimeter frame, and a specially designed gas tank sits inside the frame, lowering the fuel load and center of gravity for improved handling, yet another design borrowed from the bigger KX motorcycles. Long-travel suspension features a 36mm inverted cartridge front fork that has the capability of 18-way compression damping adjustment. Out back, the spring preload, compression and rebound damping are all adjustable on the UNI-TRAK rear suspension system.

The Kawasaki KX100 is built for the young motocross racer transitioning from a minicycle to the full-sized bikes. Based on the smaller KX85 chassis (big wheel version), the rider is quickly familiar with the larger KX100, which benefits from an increase in engine displacement, larger wheels and tires, and suspension with longer travel.

Main differences over the KX85-II is a bigger engine at 99ccm displacement. The motor breathes through a 28mm carburettor with a crescent slide to position the needle closer to the intake ports.  A large air intake cutout on the airbox and large-diameter duct to the carburettor improve airflow. Meanwhile, a carbon-fibre intake reed valve aids throttle response and a smooth-shifting six-speed transmission gets the KX100 around the track. In the braking department, both front and rear discs are mounted with shoulder bolts for easier maintenance.  In short a stronger KX85-II

For the young ones: Four-stroke

Maybe the best way to  introduce a child to the fun of off-road riding,  get the kid on a  KLX 110, the 4-stroke mini that's specially designed for young, first-time riders. Loaded with easy-to-ride features and featuring attractive KX styling, the  Although this little Stroker features racy styling and bodywork similar to the KX mini-crossers, the KLX 110 is not a race bike, it is a play bike, and might best be described as a mini-enduro.

The KLX110 is powered by an 111cc air-cooled, two-valve, four-stroke engine. This motor is the epitome of user-friendly and is even equipped with a screw-type throttle limiter mounted on the handlebar housing. This easily accessible feature means parents can control the power output with a simple turn of a screw.  The engine’s tractable power is delivered to the rear knobby via an easy-shifting, semi-automatic three-speed transmission, complete with centrifugal clutch. Newer riders gain confidence quickly by focusing on steering and balance instead of clutch coordination.   The compact fuel tank, saddle, sporty shrouds, side covers, and number plate were all plucked from Kawasaki’s smallest competition motocross machine, the popular KX65.

And while it’s primarily designed for trail riding, the KLX110 has become a favourite with adult riders who are modifying the KLX110 for competition at mini-motocross events held in backyards and arenas nationwide.

The Kawasaki KLX125 off-road motorcycle and it’s big-wheeled sibling, the KLX125L, are specially built for youth riders ready to move up from smaller bikes. They’re also perfect for novice adult riders who like the confidence-inspiring low seat height.  These easy-to-start off-road motorcycles, with their user-friendly four-stroke engines, share the same chassis and components but differ in wheel sizes and brakes. While the KLX125 sits on a 17-inch front wheel and 14-inch rear wheel, the taller KLX125L rests upon 19-inch front and 16-inch rear wheels. Plus, the KLX125 is fitted with drum brakes at both ends, while the KLX125L features a front disc brake and rear drum brake.

Powered by a torque and responsive air-cooled 125cc four-stroke single, both the KLX125 and KLX125L pump out plenty of rider-friendly power for off-road fun. The engine has been specially tuned for ample low and mid-range power and a smooth shifting five-speed transmission means there’s a gear for every riding situation. A cable-operated manual clutch, along with a digital CD ignition for quick starts, makes this quiet-running motorcycle reliable and easy to operate.

A high-tensile steel frame with a rigid carbon-steel swingarm add to the machines. durability and lightweight handling characteristics, while bumps are soaked up by a long-travel front fork and linkage-equipped single-shock rear suspension system.  The combination of a short wheelbase and a very comfortable riding position make both the KLX125 and KLX125L fun to ride on a variety of terrain. Inspired by Kawasaki’s KX models, the fuel tank, slim seat and number plates give the bike an exciting look, while the classic lime green plastic gives it a true Kawasaki identity.
