Honda CRF450R for Sale at Gold Coast Honda in Gold Coast, QLD | Specifications and Review Information
How many corners are there on your favourite motocross or Supercross track? As 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. All with the goal of letting you rail through the corners with the most precision and power you've ever experienced. The engine's power delivery starts off deep down for corner drive, and just keeps building until it's at maximum roost. Forget about clutch fade, adjustment, or hand fatigue with the new hydraulic system. Lighter than ever, the CRF450R explode out of corners when it's time to increase your lead.
NEW SINGLE MUFFLER EXHAUST
Changing the muffler's construction to a pressed-alloy design let us reshape it too, it's lighter and offers better rider ergonomics. Along with the single-muffler exhaust, naturally we gave the 2021 CRF450R a new single-pipe header. We've completely changed the routing too, bringing it 74mm closer to the centre of the bike. It's lighter, and helps improve weight distribution. The new air filter and new airbox shape helps deliver more torque. You can access the airbox through the left number plate. And because the new filter has no rubber gasket where it interfaces with the intake boot, cleaning and servicing the filter is faster and less messy than ever.
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.
We've increased the front suspension's stroke by 5mm for 2021, for better handling and rider comfort. Also, we redesigned the axle holding fixtures at the bottom of each fork leg - that increases rigidity, and enhances steering precision and suspension performance.
Kickstarting? Maybe if you're riding in the vintage class, but not here. By ditching the kick-starter 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.
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 CRF450R will do the rest, launching you into the first turn with a big advantage. It turns your bike into a holeshot-seeking machine!
NEW HYDRAULIC CLUTCH
This is huge news for the 2021 CRF450R. You get a clutch-lever pull that's lighter at its peak, even though it's paired with a new, stronger 8-plate clutch. Plus, you'll never have to worry about making a clutch-cable adjustment, even during the longest events. We've also made improvements to the clutch assembly itself. Say good-bye to clutch fade - we've upped the number of clutch plates from seven to eight, to improve durability and hook up. That means 85 percent less slip at peak horsepower and 27 percent more total torque transmission through the clutch pack.
DOWNDRAFT FUEL INJECTION
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 30metres of the race to the first turn. We've changed the angle where the fuel-injector fits into the CRF450R's intake tract. By steepening the angle from 30 to 60 degrees, the injector now sprays fuel all the way back to the throttle butterfly. The engine gets a cooler, denser fuel charge for more power and better torque.
NEW POWERFUL 449CC UNICAM ENGINE
Honda's Unicam cylinder heads combine the best of single - and double-overhead-cam designs. Our engineers redesigned the auto decompression hardware, and also moved it from the right side of the cam to the left. The result is less stalling at extreme low RPM (think deep into a turn without downshifting) as well as better rideability. The 2021 CRF450R also gets a whole new cylinder head. It boosts power from 5000 rpm up and increases exhaust efficiency.
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.
