Suzuki's all-new RM-Z450 four-stroke motocross machine is to make its world debut at this weekend's final round of the All-Japan MX Championship series.

The development programme on the prototype RM-Z450 machine will continue throughout the winter, and the bike will then make its international debut in the hands of multi-world champion Joel Smets in the World MXGP class next year.

The new RM-Z450 features an all-new, high-tech DOHC, four-valve, 449cc, liquid-cooled motor, housed in a new-concept aluminium frame, utilising various race and championship-winning technologies from the ultra-successful GSX-R development programme. New technologies from the multiple-world championship winning RM motocross development programme have also been incorporated.

The production version of the new RM-Z450 will become Suzuki's flagship model in its expanding four-stroke motocross range, and will be ready to hit Suzuki showrooms in August 2004.

Team Suzuki's All-Japan MX champion, Akira Narita, will debut the new RM-Z450 at this weekend's final round of the 2003 series. Narita secured his second title in a row at the previous round of the series and is aiming to give the new machine a winning debut.
