The CRF450R’s liquid-cooled, 4-stroke, single-cylinder Unicam 449cc engine now provides a full 11% more top-end power than the outgoing model. The power and torque are stronger everywhere, but especially through the midrange torque area and at the top end, with a major increase in rpm, peak power and over-rev. The engine now uses a scavenge pump to distribute the oil by force (rather than spray) for both transmission and clutch, reducing friction, improving lubrication efficiency and greatly reducing pumping losses.
The completely redesigned chassis gives the rider absolute control of the CRF450R’s new power-up engine. The goals for this seventh generation of CRF aluminium beam frame were clear: to improve turning performance, front-end stability and traction, plus rear-wheel drive with elevated levels of rider feedback and predictability.
Titanium Fuel Tank
The new CRF450R now incorporates a 6.3L titanium fuel tank, which weighs 513g less than the plastic design before it. The loss of half a kilo high on the machine contributes significantly to the lower centre of gravity.
New rider controls
The rider controls and displays are now rationalised together and sited on the left handlebar: engine stop button, EFI warning, plus EMSB (Engine Mode Select Button) and LED indicator. Honda’s EMSB is the key that puts instant engine character adaptability at the rider’s command. With the machine stopped and engine at idle, a simple press and hold of the button for just under a second selects the next map in sequence.
