2021 Honda CRF450RWE for Sale

Comfort

• SLIM BODYWORK: We’ve slimmed down the CRF450RWE’s bodywork, and reduced the total number of pieces. It makes it a lot easier to move around on the bike, and that maximizes your riding freedom. While we were at it, we reduced the total number of fasteners needed to remove the body panels—maintenance off the bike just got easier too.
• FRESH NEW STYLING: The CRF450RWE features an exclusive graphics package by Throttle Jockey, made just for this bike. Plus, our “in mold” graphics help keep your bike looking good. You’re most definitely going to stand out wherever you ride!
• RENTHAL "FATBAR": The aluminum Renthal Fatbar features a bend that’s even better than the legendary Honda “CR” bar. It’s the standard of excellence—you’re gonna love it!, the CRF450RWE gets special Renthal grips.
• PREMIUM DID DIRTSTAR RIMS: Absolutely the best you can get here, these premium DID DirtStar LT-X rims are only available on the RWE, and are definitely a serious upgrade.
• SEAT: Sometimes you need to think out of the box—that’s what we did with the CRF450RWE’s seat. We moved the attaching bolts from the rear to the front, and the tongue from the front to the rear. Plus, on the RWE, you get an exclusive Throttle Jockey seat cover.
• FLAT SEAT/TANK JUNCTION: The CRF450RWE 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.
• CABLE ROUTING: You may not notice it at first, but re-routing the CRF450RWE’s throttle cables and hydraulic clutch line let our engineers shave almost half a pound off the bike. Light is always right!

Convenience

• AIRBOX AND FILTER: The airbox shape helps deliver more torque, and now you can access the airbox through the left number plate. The CRF450RWE gets a special, exclusive, Twin-Air filter element that needs no rubber gasket where it interfaces with the intake boot, cleaning and servicing the filter is faster and less messy than ever.
• ELECTRIC STARTER: Kickstarting? Maybe if you’re riding in the vintage class, but not here. By ditching the kickstarter entirely, our engineers can make the CRF450RWE 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 CRF450RWE is all about.
• SWITCH ASSEMBLY: Check out the controls on the 2021 CRF450RWE. We’ve made them lighter, and more intuitive. Controls used to be your bike’s shifter, clutch, and brakes. Now you have things like launch assist, selectable power modes, and more. We believe they should be easy to use, and we’ve just made them easier.

Engineering

• HYDRAULIC CLUTCH: This is huge news for the 2021 CRF450RWE. Out with the old cable-actuated clutch, and in with the first hydraulically actuated clutch we’ve offered outside of our works bikes. Made by Nissin, it’s the same design as in our Grand Prix MX machines, and performs better than third-party conversions. You get a clutch-lever pull that’s ten percent 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.
• EXCLUSIVE HINSON CLUTCH BASKET: While the hydraulic clutch is getting all the attention, we’ve made even more improvement with the parts that do the work: the clutch assembly itself. First of all, the CRF450RWE gets a premium clutch basket made by Hinson. Say good-bye to clutch fade—we’ve upped the number of clutch plates from seven to eight, to improve durability and hookup. That means 85 percent less slip at peak horsepower, and 27 percent more total torque transmission through the clutch pack. Even the spring is stronger, but thanks to the hydraulic actuation, clutch-lever pull is lighter than ever. A tasty Hinson clutch cover tops it all off.
• 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 CRF450RWE will do the rest, launching you into the first turn with a big advantage. It turns your bike into a holeshot-seeking machine!
• HONDA SELECTABLE TORQUE CONTROL (HSTC): Notice that button on the handlebar by the clutch perch? The CRF450RWE 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.
• 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.
• COMPACT FUEL PUMP: No detail is too small for our engineers—especially if they can make it smaller and lighter. That’s what they did to the 2021 CRF450RWE’s fuel pump. Why carry around any extra weight when you don’t have too? While they were at it, they reduced the number of attaching fasteners from six to four.
• RADIATOR SHROUDS: Using computer-aided Computational Fluid Dynamics, we’ve fine-tuned the CRF450RWE’s radiator shrouds to increase cooling. They’re now a one-piece design, but more important, better cooling equals better power, longer into a race, especially when you’re really on the gas and working the engine hard.
• REAR BRAKE PADS: Brakes are for more than just stopping: they help you set up the bike in turns and jumps. Which is why we pay so much attention to detail like brake pads. They’re designed to last longer and give you more stopping power—a real win/win to help you win.
• 260MM FRONT BRAKE: The CRF450RWE’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.
• TITANIUM FUEL TANK: Grams and performance count, and the CRF450RWE uses a titanium fuel tank. Light and strong, it maintains the same capacity as our previous plastic unit, while freeing up more space and helping to centralize fuel mass.

Handling

• LIGHTER, NARROWER FRAME: Great handling starts with a superior frame, and we’ve made some big changes to our 2021 CRF450RWE’s chassis. First, it’s lighter—over a pound and a half lighter. By making the frame’s main spars narrower, we saved weight, but more important we made the chassis more responsive by reducing lateral rigidity 20 percent. The result is a bike that gets into, around, and out of corners faster.
• NARROWER SWINGARM: Designed in conjunction with the frame, by using narrower main members (just like the frame uses narrower main spars), we’ve matched the swingarm’s lateral rigidity to the rest of the chassis. What you get is a balanced, fully integrated approach to frame stiffness, letting you get around corners faster and with better feel.
• LIGHTER SUBFRAME: We totally redesigned the rear subframe to make it nearly three-quarters of a pound lighter, and along the way simplified its construction too.
• BATTERY BOX: Three key features changed here: The battery box is lower, for an improved center of gravity. Second, it’s also easier to service. And third, it’s now water-tight, so there's nothing to worry about when racing in wet conditions.
• FRONT SUSPENSION: 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.
• TRIPLE CLAMPS: The CRF450RWE is a perfectly matched package. With the frame and swingarm featuring a retuned lateral stiffness, and the fork legs featuring a new, stiffer axle fixture, we joined the two with new upper and lower triple clamps. Working in concert, they help improve and balance total rigidity, responsiveness and turning performance.
• REAR SUSPENSION: The 2021 CRF450RWE’s frame design gave us the opportunity to fit a rear shock. With the Works Edition, you get special A-kit suspension. We’ve optimized the shock’s shape to match the frame, and gave it settings to work with the chassis. The shocks valving resets faster for better response. In addition, we’ve fit a steel spring that’s way lighter, cutting weight without cutting performance.
• SHOWA SPRING FORK: The 49mm Showa fork features a conventional spring design that helps increase the CRF450RWE’s front-suspension precision, handling and feel. On the RWE, the inner rod has a special Kashima coating, and the outer tubes feature a titanium nitrate coating. The spring rate provides better bottoming resistance and improved handling.
• SINGLE-MUFFLER EXHAUST SYSTEM: The CRF450R gets a new exhaust this year, but the RWE’s is even more special. It’s a titanium construction, made specially for us by Yoshimura. Super light and super trick, the exhaust tucks away for better ergonomics too.

Performance

• EXCLUSIVE WORKS EDITION: Homologated for racing and available in limited numbers, the CRF450RWE Works Edition includes all the improvements of this year’s CRF450R plus a special hand-ported cylinder head; Hinson clutch basket and clutch cover; Twin Air filter, Throttle Jockey graphics and seat cover; upgraded DID DirtStar LT-X rims; an exclusive Yoshimura exhaust system including a titanium header; titanium nitride-coated lower fork legs and shock shaft; revalved suspension; an RK gold chain; special ECU settings; and black triple clamps.
• 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.
• REVISED DECOMPRESSION SYSTEM: You can’t see this unless you take the engine apart, but you’ll notice it on the track. 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.
• EXCLUSIVE CYLINDER HEAD: The 2021 CRF450RWE gets a whole cylinder head this year. Its biggest feature: an oval-shaped centralized exhaust port. Plus, the RWE gets some exclusive porting touches and engraving. The cylinder head cover is red, so it really stands out.
• TITANIUM INTAKE VALVES: Lightweight titanium intake valves cut down on reciprocating mass and permit the use of smaller valve springs, reducing overall engine height.
• FUEL INJECTOR BODY POSITION: We’ve changed the angle where the fuel-injector fits into the CRF450RWE’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. It’s little details like this that put the CRF450RWE up front.
• DOWNDRAFT FUEL INJECTION: The CRF450RWE features a downdraft intake tract and FI body to help increase both power and fuel-metering precision. It’s part of the reason the CRF450RWE offers such explosive power and massive torque, especially out of the starting gate and in the critical first 100 feet of the race to the first turn.
• DOUBLE-SPRAY INJECTOR SETTINGS: The CRF450RWE’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.
• DUNLOP MX33 TIRES: These are the skins of choice for serious MX racers right now, so naturally, we fit the best to the 2021 CRF450RWE. The Dunlops hook up in a wide variety of conditions, and help you put the CRF450RWE’s improved cornering performance to the ground.
• CYLINDER HEAD LAYOUT: The CRF450RWE uses our latest finger-follower rocker design. The Unicam cylinder head remains one of the most efficient in the MX world, giving you the design and performance of a double-overhead-cam layout but the compactness of a single-overhead-cam design.
• 13.5:1 COMPRESSION RATIO: Honda engineering at its best: The CRF450RWE’s cylinder head features a highly refined combustion-chamber shape and generous squish area, allowing an impressive 13.5:1 compression ratio for superior efficiency and power.
• SKID PLATE: A factory skid plate is light and offers the engine and lower-frame protection that a racer demands.
