Your Trophy Awaits.
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.
Next, the CRF450R's revolutionary KYB Air Fork features new high-speed/low-speed compression and rebound damping, letting you dial in the CRF450R's suspension in much quicker. The new exhaust port header design and compact dual exhaust further enhance mass centralization. And the new head design provides more top end power and over-rev.
Plus, there’s stronger transmission gears, a new piston, more flywheel mass, a new rear shock that's easier to adjust and a new 260mm front brake lets you haul down all that speed with more stopping power. The list just keeps going on.
Engine Mode Select Button: Huge news for 2015, and an industry first for MX bikes. Not to be confused with a launch mode selector, this handlebar-mounted button lets you dial in engine power delivery character with a push of your thumb. Choose between Standard, Smooth, and Aggressive, depending on track conditions.
New Cylinder Head And Piston: The CRF450R’s new cylinder head features a right-side exhaust port exit that helps the engine deliver more top-end power and over rev, plus better low-end torque feel. A new piston heat treatment adds durability, too.
Revised KYB PSF Air Fork: The CRF450R's 48mm inverted KYB PSF (Pneumatic Spring Fork) air fork is even better for 2015, with new high/low-speed compression and rebound damping. It weighs less than a conventional spring fork, and adjusting the spring rate is as easy pumping air.
