Unicam Engine
The Unicam® cylinder head offers a compact, lightweight design with a narrow valve angle, which improves combustion chamber efficiency, increases compression ratio, and lowers the centre of gravity. |
Smoother Airflow
Torque output has been maximized with a unique airbox shape and filter design. The filter is easily accessible and features a gasket-less design for quicker and easier cleaning and servicing. |
Revised Exhaust
In combination with its less-restrictive air-intake system, the CRF450R’s revised exhaust with straighter airflow means smoother engine operation in the mid- to high-rpm range and more-controllable acceleration. |
Hydraulic Clutch
Big power requires a strong clutch, and this bike delivers with a smooth-operating hydraulic clutch. Ditching the cable improves consistency, control, and feel at the lever. The clutch capacity is generous, along with an extra plate and spring to maximize power transfer and durability. |
Honda Selectable Torque Control (HSTC)
Honda Selectable Torque Control (HSTC) works to minimize rear wheel spin (thus wasted forward drive) and maximize traction. It doesn’t use a wheel-speed sensor, and, importantly, maintains feel at the throttle while managing power — ignition timing and the PGM-FI system are adjusted when the rate of change of rpm goes over a set amount. With three settings plus off to choose from, you can have your bike dialed no matter how much traction there is. |
HRC Launch Control
We’re talking about a special ECU program here: push the button to select the mode, hold the throttle open, release the clutch, and the bike will do the rest, launching you into the first turn with a big advantage. |
Engine Mode Select Button
This simple 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. |
ECU Settings
Our engineers never stop searching for ways to make it easier to go faster. The ECU settings combine with the other chassis and powertrain improvements to make the CRF450R an all-around better performer. |
