KAWASAKI KX Models/Series Timeline, Specifications & Photos

In 2021, the Japanese motorcycle manufacturer added to its off-road lineup the Kawasaki 450XC, a new cross-country racer that retained all the championship-winning performance and factory-style features of the KX450 machine.

In addition, the added XC abbreviation was translated into specific engine tuning and suspension settings, 21-inch front and 18-inch rear wheels shoded with enduro-type tires, and conventional standard features such as a side stand and a skid plate.

The ultimate combination of a championship-winning package consisted of a 449cc liquid-cooled engine, a slim aluminum perimeter frame, a Showa A-KIT technology suspension, a hydraulic clutch, and an electric starter, which resulted in a cross-country racing machine with a tune for more experienced riders.

In the aluminum perimeter frame, the engine was used as a stressed member that contributed to the frame rigidity, but also, the frame was made of a combination of forged, extruded, and cast parts, designed with a balance of torsional and longitudinal rigidity for quick handling.

As for ergonomics, the 2021 Kawasaki 450XC featured wide footpegs, a bodywork designed for better rider movement with long, smooth surfaces, and the fuel tank offered a flat progression to the seat that gave the rider more freedom of movement.

As for braking performance, the bike packed a single petal disc with a hydraulic caliper on the front wheel and a 250 mm petal disc with a hydraulic caliper on the rear wheel that offered optimum braking power.

With a great history in off-road racing, Kawasaki adds to its off-road line-up the new 2021 KX 250 XC. The new motorcycle was specially tuned and designed to perform under hard off-road conditions, such as both wood and desert race courses.

The new model keeps the performance and style features of the KX 250, but that’s when the XC comes into the picture with special engine tuning, suspension settings, and more standard features, such as a side stand and an engine protection plate.

The part responsible for driving the Kawasaki KX 250 XC through mud and sand is a 249cc, four-stroke, four-valve, liquid-cooled DOHC, high-revving engine, working in tandem with a five-speed manual gearbox.

For better performance and handling of the KX 250 XC, the lightweight frame is made of aluminum and uses the engine for better rigidity.

For the rider to have a good start, the KX 250 XC has a Launch Control option allowing the tire to gain more grip in the first few seconds. The model has a 270 mm front brake disc and KX450 master cylinder with XC brake pads, and a 240 mm rear disc offering a strong level of brake control.

At the time of writing (2022), the 2021 Kawasaki KX 250 XC was selling for $6,900.

Its liquid-cooled, two-stroke 65cc engine and light weight chassis delivers strong controllable power and exceptional handling that is the ultimate recipe for winning races. The 33mm front forks and four-way adjustable rebound damping are capable of performing at the highest level in aggressive terrain, while the rear is fitted with Kawasaki’s Uni-Trak single-shock system with adjustable rebound damping and fully adjustable spring preload.

The 2017 KX 450F motorcycle is the most powerful, lightweight, and agile KX 450F ever. Developed from the highest levels of racing, this championship bike has advanced technology sourced straight from the world’s premier race team—another reason why the KX 450F is The Bike That Builds Champions. The characteristics of the 450cc engine are similar to those of the 2016 model. Last year's engine had a pop that was hard to escape, but Kawasaki seems to have remedied this for 2017.

The adjustable rear and front suspension allow you to choose the setting in the 20-way compression damping and travel among other settings. The news for 2017 is a lighter case as a result of a revised radiator including the fuel tank and the reinforced ribbed seat.

The 85 is powered by a 84cc, 2-Stroke, liquid-cooled, single cylinder engine. With a cylinder bore of 1.9 in and stroke of 1.8 in, its motor is oversquare, meaning that the cylinder bore (width) is greater than the stroke (length). This makes the engine more powerful than one of similar displacement with a smaller bore. The engine is supported by electronic fuel injection which ensures smooth and timely fuel delivery. Electronic ignition makes starting your bike a breeze and ensures a consistent throttle response.
