EMBRACE WINNING, ON OUR BEST ENDURO EVER
EMBRACE WINNING, ON OUR BEST ENDURO EVER
Enduro racing is an ever-changing challenge--the terrain, the competition, the weather, the course. And you can't be static in a changing environment if you want to prevail. That's why we've given the class-leading Honda CRF450RX so many big changes this year. Basically, it gets all the same awesome upgrades as our CRF450R: new frame, cylinder head, hydraulic clutch, clutch internals, fuel injection, single-muffler exhaust, and more. Plus we've fine-tuned the suspension specifically for enduro riders, shaved approximately four pounds off last year's bike, and even hooked you up with factory handguards. All in all, it's the highest performing bike we've ever offered in the class. Embrace the changes--then embrace victory.
COMFORT
• SLIM BODYWORK: We've slimmed down the CRF450RX'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.
• FACTORY HANDGUARDS: You asked; we delivered. The 2021 CRF450RX comes with handguards installed right from the factory.
• 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!
CONVENIENCE
• AIRBOX AND FILTER: Along with the air filter, the airbox shape helps deliver more torque. You can access the airbox through the left number plate. And because the filter has no rubber gasket where it interfaces with the intake boot, cleaning and servicing the filter is faster and less messy than ever.
• ELECTRIC START: Kickstarting? Maybe if you're riding in the vintage class, but not here.
• SWITCH ASSEMBLY: Check out the controls on the 2021 CRF450RX. We've made them lighter, and more intuitive. Controls used to be your bike's shifter, clutch, and brakes.
ENGINEERING
• HYDRAULIC CLUTCH: This is huge news for the 2021 CRF450RX. 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.
• CLUTCH ASSEMBLY: 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. Say good-bye to clutch fade--we've upped the number of clutch plates from seven to eight, to improve durability and hookup.
• HONDA SELECTABLE TORQUE CONTROL (HSTC): Changing terrain requires changing power character. No worries: The CRF450RX features 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.
HANDLING
• LIGHTER, NARROWER FRAME: Great handling starts with a superior frame, and we've made some big changes to our 2021 CRF450RX's chassis. First, it's lighter--over a pound and a half lighter.
• 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.
• 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.
PERFORMANCE
• DUNLOP GEOMAX AT81 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.
• 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.
• 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.
