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 CRF450R will do the rest, launching you into the first turn with a big advantage. It turns your bike into a holeshot-seeking machine!
Kickstarting your bike is so 2016. By ditching the kickstarter entirely, our engineers can make the CRF450R lighter. Electric starters and lithium-ion batteries are so light now and so good that putting them on a bike like this is a win/win combination. And winning is what a CRF450R is all about.
We shaved an additional 795 g (1.75 lb) from this year’s CRF450R—a surprise considering how light this bike already is. Where did it come from? Mostly from eliminating the kickstart option, but weight is weight, and on a racebike less of it is almost always better.
The CRF450R’s large front-brake disc measures a whopping 260 mm. You get great brake feel and a pattern that cuts down on weight. Front and rear brake-disc guards are part of the package too.
Honda’s Unicam cylinder heads combine the best of single and double-overhead-cam designs. The configuration contributes to a compact engine that saves weight over a comparable dual-overhead-camshaft motor and also permits a narrow included valve angle. This flattens the combustion chamber to facilitate ignition flame propagation, allowing a high compression ratio. Since less space is taken up in the cylinder head, the camshaft sits lower in the head for a more compact engine and a lower center of gravity.
The CRF450R features a downdraft intake tract and FI body to help increase both power and fuel-metering precision. It’s part of the reason the CRF450R offers such explosive power and massive torque, especially out of the starting gate and in the critical first 30 meters (100 ft) of the race to the first turn.
"The CRF450R’s fuel-injection system sprays twice per intake cycle. That helps increase fuel atomization without adding the weight or complexity of a second injector. The better fuel atomization means more power in the midrange and on overrev—you’ll feel it the first time you race. "
Comfort & Handling
The new aluminum Renthal® Fatbar® features a new bend too. The old Honda “CR” bend was legendary for getting it right, and this new fat bar is even better. It’s the new standard of excellence—you’re gonna love it
The CRF450R features a flat seat/tank junction, including a titanium fuel tank. The superior ergonomics make it easier to move forward and back on the bike, increasing your control.
They may not help you go faster, but the new black DID® rims this year sure look good.
