2020 Honda® CRF450RX

Enduro riders are unique—they need the performance every winner wants, but in a unique package. We hear you—and that’s why we build the Honda CRF450RX, with all the power, handling and refinement of our dominant CRF450R MX’er, but fine-tuned for enduro use. With features like a bigger fuel tank, a sidestand, an 18-inch rear wheel, and special suspension settings. Plus all the updates we’ve given our CRF450R, like Honda Selectable Torque Control, a new battery box that relocates the battery by 28mm for a lower center of gravity, new rear brake pads that last longer and improve stopping power, and even new graphics.

Features may include:

• Honda SELECTABLE TORQUE CONTROL (HSTC)

Notice that new button on the handlebar by the clutch perch? New for 2020, the CRF450RX gets our Honda Selectable Torque Control (HSTC). You can choose from one of three settings to perfectly dial your bike in depending on how much traction is available.

• 260mm FRONT BRAKE

The CRF450RX’s large front-brake disc measures a whopping 260mm. 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.

• ELECTRIC START

Kickstarting? Maybe if you’re riding in the vintage class, but not here. By ditching the kickstarter entirely, our engineers can make the CRF450RX 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 CRF450RX is all about.

• 449cc UNICAM® ENGINE

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.

• DOWNDRAFT FUEL INJECTION

The CRF450RX features a downdraft intake tract and FI body to help increase both power and fuel-metering precision. It’s part of the reason the CRF450RX offers such explosive power and massive torque, especially out of the starting line and in the critical first 100 feet of the race to the first turn.

• DUNLOP GEOMAX TIRES

The CRF450RX’s Dunlop Geomax tires are specially designed for enduro use. The AT81 tires are spec’d at 90/90-21 for the front and 120/90-18 for the rear. You read that right: the CRF450RX rolls on an 18-inch rear wheel.

• RELOCATED BATTERY/BATTERY BOX

For 2020, we designed a new battery box for the CRF450RX that moves the battery 28mm lower. That helps lower the overall center of gravity, which is always a benefit for responsive handling.

• RENTHAL "FATBAR"

The aluminum Renthal Fatbar features a bend that’s even better than the legendary Honda “CR” bar. It’s the new standard of excellence—you’re gonna love it!

• FLAT SEAT/TANK JUNCTION

The CRF450RX 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.
