2015 Honda CRF 450, There’s big news for 2015: an all-new Engine Mode Select button lets you choose between three settings (Standard, Smooth, and Aggressive), just by pushing a handlebar-mounted button. It's an industry first for MX bikes, and it's going to make tuning your bike for changing track conditions a snap. With our available HRC Fuel Injection Setting Tool, it’s easily adjustable to specific track conditions and refines your settings in place of the smooth and aggressive settings on the engine mode selector.
