KX450-SR

The 2021 Kawasaki KX450–SR is the pinnacle of Kawasaki’s four-stroke motocross GP technology, with class- and race-leading power delivery controlled by state-of-the-art suspension, lightweight high-tech chassis and sizzling innovations. 
 
The KX450–SR, the result of ongoing development by technicians from the Japanese factory’s Akashi race department and the KRT base in Europe, will be campaigned in the FIM World MXGP Motocross Championship by France’s Romain Febvre and Italy’s Ivo Monticelli under the KRT banner; it is a natural cohesion of OE components and unobtainable exotic items such as Factory Showa suspension.
 
The 'SR' also reflects many of the same outstanding features found on the standard KX450 machine available from any Kawasaki off-road dealer with the leanest, most ergonomically-precise chassis ever on a KX450, a perfected E-starter with automated centrifugal decompression system and the exclusive finger-follower valve actuation, a valve train designed by Kawasaki’s MotoGP & World Superbike engineers which enables larger-diameter valves and more aggressive cams to derive the optimum from a new engine which boasts an increase in peak power of approximately 2.5 kW (3.4 PS) whilst maintaining Kawasaki's renowned low-rpm performance through a flatter torque curve to make it even easier to get on the gas at all times.

KX250F-SR

The KX250 four-stroke was launched in 2004 and has been continually developed ever since. A winning machine in MX2 and Supercross at international level and equally successful in national and club racing, the KX250 is a formidable racing machine.
 
At the final step in the MX competition ladder before the pinnacle of MXGP the KX250 displays agility, power and predictability plus season-long durability and easy maintenance and is “first choice” for many individual riders and racing teams across the world.
 
Continual development to maintain the most impressive race-long performance on the market with enviable durability has always been the aim of Kawasaki engineers and the 2021 KX250 features a new engine with amended bore and stroke to increase power output and offer even smoother power delivery while finger-follower valve actuation, as already featured on the KX450, enables a higher rev limit and more aggressive cams.
 
Complemented by a lightweight slim line aluminium perimeter frame with a new fork, stronger brakes, a new coned-disc-spring hydraulic clutch and E-starter this performance advantage translates to quicker lap times, making it the fastest most-competitive KX250 ever.
 
Proof of the outstanding competitiveness of the 2021 Kawasaki KX250 was already displayed during the closing stages of the 2020 FIM World WMX Women’s Motocross Championship when New Zealand’s Courtney Duncan raced the production model to victory at the final two rounds of the series to clinch a second consecutive world title since going Green.
