Kawasaki launches new XC

Kawasaki launches new XC off-road models Kawasaki Motors has re-entered off-road and enduro with the launch of two new models, the 2021 KX450XC and KX250XC. Kawasaki is proud of its off-road racing history with, they remind us, more than 25 championships in WORCS, National Hare & Hound, GNCC, and Endurocross over the past 20 years. Remember team Green in SA? It would be awesome to see a few green machines on the start lines… Kawasaki have kicked back into off-road officially with the new KX250XC and KX450XC models for 2021. Based naturally on their motocross counterparts with common engine, frame, chassis and styling, the closed-course XC models differ with new and unique engine tuning, suspension settings and off-road specific components. 2021 KX XC model highlights: • New off-road engine mapping and tuning • New final drive gearing • Electric start • Softer Showa suspension settings • 21” front wheel and 18” rear wheel combination • Dunlop GEOMAX AT81 tyres • New Braking brake rotors with Nissin master cylinders, calipers and pad compounds • New Skid plate • New Kickstand XCs in detail – Engine • The four-stroke, single cylinder, DOHC, water-cooled engine packages have revised mapping and settings for off-road racing and features an electric start, activated by the push of a button and powered by a compact Li-ion battery. • Kawasaki say they brought top-level road racing technology to the KX XC valve trains, using designs from Kawasaki World Superbike engineers. It uses a finger-follower valve actuation, enabling larger-diameter valves and more aggressive cam profiles. The intake and exhaust valves are formed from lightwight titanium, while a bridged-box piston uses the same design as the Monster Energy Kawasaki race team’s factory motorcycles. The piston also features a dry film lubricant coating on the skirt to reduce friction and improve performance. • The new XCs use a close-ratio five speed transmission but with shorter gearing than the MX counterparts, with a final gear ratio of 51/13 (on both 450 and 250 models). The transmission is paired with a coned disk-spring hydraulic clutch which they claim sees minimal changes in play as the 48 DIRT & TRAIL MAGAZINE AUGUST 2020 DIRT & TRAIL MAGAZINE AUGUST 2020 4 9
