Now Honda has two versions of their popular dual sport – the CRF250L and CRF250L Rally. Both pack a nice punch with dual overhead cams on a fuel injected 249cc power plant, and the styling is 100% on the mark.
Now Yoshimura introduces the RS-4 Race Series full system for the new dual sport machine. By giving the new CRF250L more power and torque, the RS-4 provides more punch at bottom end with out sacrificing the mid and top power. The new system also removes a good amount of weight from the stock unit. Those that love the Yoshimura RS-4 sound will love the way it makes the new CRF250L Rally sing!
