The 2018 CRF450RX is identical in almost every area to the 2018 CRF450R, but has some crucial changes to create an uncompromising enduro focus. Both front and rear suspension are less firm, with lighter compression damping and a lower spring rate for the shock. It uses an enduro-standard 18in rear wheel, and sidestand and 8.5L fuel tank are also added for practicality and extended range.
