HONDA CRF450R

HONDA CRF450R

LIGHTER. FASTER AND RAZOR SHARP.

How many corners are there on your favourite motocross or Supercross track? Each one of those leads directly from the starting gate to the winner’s circle—at least when you’re riding a redesigned 2021 Honda CRF450R. New chassis. Major engine overhaul. New suspension. New bodywork. Both with the intention of helping you to fly through the corners with the best accuracy and strength. The engine's power supply continues down to the corner and then works up until the full roost is achieved. Forget about the buckling of the new hydraulic system, modification, or manual fatigue. The CRF450R is lightweight than ever because the lead is more explosive. Arriving late 2020.

POWERFUL 449CC UNICAM ENGINE

A brand new cylinder head is now available for the 2021 CRF450R. Its main feature is a central exhaust port with an oval shape. Along with the new single-muffler exhaust, it improves energy from 5000 rpm and exhaust efficiency.

ELECTRIC STARTER

Kickstarting? Maybe if in the antique class you are riding, but not here. Our engineers will make the CRF450R lighter by pulling the kick starter full. Electric starters and lithium-ion batteries are so small now that it's a win-win mix to mount them on a bike like that.

HRC LAUNCH CONTROL

Here we talk about a special ECU program: press the button, to pick the mode, to keep the throttle open, to release the clutch, and the CRF450R will do the rest. Your bike is turned into a holeshot!

HONDA SELECTABLE TORQUE CONTROL

Notice that button on the handlebar by the clutch perch? The CRF450R 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.

DOWNDRAFT FUEL INJECTION

CRF450R features a downdraft intake tract and FI body to help increase 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 30metres of the race to the first turn.

NEW HYDRAULIC CLUTCH

We provided outside our working bikes with the old wired clutch and the first hydraulically driven clutch. The architecture is the same as in the Grand Prix MX machines produced with Nissin and does better than conversions from third parties.

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. Also, check out the controls on the new 2021 CRF450R.

BRAKES

The big front-brake disc of the CRF450R measures an impressive 260mm. You get a good feeling for braking and a weight-reducing sequence. Brake disc guards both on the front and back are also included with the kit.

FRONT SUSPENSION

For 2021, for greater handling and comfort, we raised the front suspension stroke by 5 million mm. Furthermore, at the bottom of every fork leg, we have upgraded the axles holding fittings that increase rigidity and improve control accuracy and suspension stability.

SHOWA SPRING FORK

The Showa 49mm fork has a traditional spring mechanism to improve the strength, handling and sound of the CRF 450R front suspension. The pace promises greater resistance to bottoming and greater exploitation.

NEW LIGHTER SWINGARM

The swing arm is thinner, and in combination with the current frame, we have merged the lateral rigidity of the swing arms with other frames with smaller main components (just as the frame has thinner spars).

11 / 15

NEW BATTERY BOX

Three key features changed here: The battery box is lower, for an improved centre of gravity. Second, it’s also easier to service. Third, it’s now water-tight, so there's nothing to worry about when racing in wet conditions.

12 / 15

NEW SINGLE-MUFFLER EXHAUST

Naturally we have given the CRF450R 2021 a new one-pipe header, along with the single-muffler exhaust. We have modified the path entirely and moved it 74 mm closer to the center of the vehicle. It is lighter and adds to the transfer of weight. The new air filter and airbox design lead to a more torque effect.

13 / 15

NEW TRIPLE CLAMPS

We connected the two of them with new upper and lower triple clamps with the frame and swingarms with a different lateral steadiness and the fork legs with a different, steeper axle base. Acting together, they lead to increased rigidity, flexibility, and consistency.

14 / 15

REAR SUSPENSION

The new frame configuration of the 2021 CRF450R gives us the chance to install a new rear shock. In order to balance the frame, we streamlined its structure and gave it the current chassis configuration to work. The valve shocks resets quicker for stronger reaction.
