Connected as One

This is the most complete motocross package we’ve ever created. And it’s also the first production bike that allows you to connect wirelessly and dial in your own customised engine settings - and maximise your winning potential.

The lightweight electric start saves vital seconds when you’re under pressure – and the reverse head engine gets a high compression top end and optimised ECU for even stronger race winning power.
