Kawasaki has unveiled its 2020 motocross range, revealing the KX250 has received a number of engine and suspension updates for the new year model, while the KX450 will remain largely unchanged after undergoing a complete overhaul this year.

The 2020 KX250 updated engine features a new finger-follower valve actuation, a valve train designed by Kawasaki’s World Superbike engineers and enables a higher rev limit, and more aggressive cams for harder-hitting power.

A new short-stroke configuration lends itself to high rpm-focused engine character, while the larger bore allows larger intake and exhaust valves, enabling greater airflow for increased high-rpm performance.

A new bridged-box bottom piston contributes to a higher compression ratio, while a revised airbox and intake duct, larger diameter throttle body, and updated exhaust system further contribute to increased engine performance.

On the front, an oversized semi-floating 270mm Braking petal disc and dual-piston caliper with new brake pad materials offer solid control. In the rear, a new larger-diameter 250mm Braking petal disc and new lighter-weight master cylinder give you the stopping power to get ahead.

A new larger diameter coil spring 48mm KYB front fork offers improved action at the initial part of the stroke. The large-diameter inner tubes enable the use of large 25mm damping pistons for smooth action and firm damping. Uni-Trak rear suspension with a new KYB shock featuring dual compression (high-speed and low-speed damping) adjustability helps soak up whatever the track throws your way.

Optimised frame rigidity with a new front engine mount contributes to smoother rear suspension performance for maximum bump absorption and increased traction. The centre of gravity and key frame dimensions are optimised for maximum forward drive from the rear wheel.

Kawasaki class-leading ERGO-FIT adjustability allows riders to find their optimal fit and comfort with four-way adjustable handlebar positions and two footpeg positions to choose from.

Undergoing a complete overhaul for MY19, the 2020 KX450 delivers strong, responsive power, thanks to the engine that features a finger-follower valve train. Crafted with the same design used by Kawasaki factory race teams, the 449cc engine produces broad torque and strong power across the entire rev range.

49mm Showa coil spring front fork combined with A-KIT technology deliver superb suspension and handling. Large-diameter inner tubes allow the use of large damping pistons for race-winning performance while a large-diameter front axle improves front-wheel traction. The Uni-Trak rear suspension system ensures optimal rear-wheel traction.

The most advanced KX450 motorcycle yet features stopping power to match its incredible acceleration capability. Up front, an oversized 270mm Braking petal disc with dual-piston caliper offers sharp response and a strong, consistent feel. In the rear, a large-diameter 250mm Braking petal disc complements the front for race-ready performance.

You can find your best performance with the Kawasaki ERGO-FIT advantage – four handlebar positions and two footpeg positions allow you to tailor the KX450 motorcycle to your body size, riding style and preference. Wide footpegs ensure excellent grip for optimum comfort and control.

Conserve energy and ride smarter with an electric start and hydraulic clutch. A lithium-ion battery ensures strong and reliable starting performance, eliminating the need for a backup kickstarter. The hydraulic clutch offers a direct feel and consistent actuation even as engine temperatures rise while also offering a light pull at the lever.

The MY2020 KX65 and KX85 also remain largely unchanged for the new year. Pricing and availability in Australia is still to be confirmed. For more information, visit www.kawasaki.com.au.
