2011 Honda CRF450R
The bike that Redefined the Open Class.
Long regarded as the bike of choice in the big-bore motocross division, the 2011 CRF450R incorporates improvements that will help this bike retain its premier standing. The prodigious powerband is now even stronger thanks to more low-end pull and midrange grunt along with enhanced throttle response via a new throttle body. Revised suspension linkage and settings yield improved control, increased ride plushness and enhanced rear-wheel traction. A new HPSD produces even better tracking traits than before, and a new muffler meets the 94-decibel sound level required by some racing organizations in 2011. All this and more make the 2011 CRF450R a shoo-in to maintain its dominant role among open-class MX bikes.
Motocross is a battle, and you‚better bring your a game whenever you show up either that, or be prepared to eat a bucketful of roost. But when you‚Äôre on a 2011 Honda CRF450R its everyone behind you wholl be savoring that dirt-flavored banquet. Why? Because weve given the CRF450R some serious upgrades.
First, the 450 gets a new throttle body, new fuel injector, and new ECU mapping so the engine makes more low end and midrange torque, and also offers even better throttle response. The power is easier to control, but without any loss of top end—better than ever for intermediate and expert riders alike. And our chassis designers were just as busy, updating the CRF450R subframe and taking the opportunity to fine-tune the subframes stiffness. A new rear shock link and lower shock mount for improved front/rear balance and better suspension action especially over square-edged bumps.
And finally, new 2011 AMA rules state that every MX bike will have to meet the new 94 decibel rule. Both our CRF450R and CRF250R do that easily, thanks to a new exhaust system that works in conjunction with the new FI settings. So while the other guys might just change a muffler, thats just where we started. And the first time the gate drops, its gonna show.
How bad do you want to win in 2011?
The 2011 CRF450R is upping the ante in the open class. First, its revised fuel injection system lets it deliver the kind of predictable power you need with an engine this strong, while the new throttle body and ECU mapping fatten up the midrange and bottom end, making the CRF450R easier to ride. New suspension settings along with the new bottom link give you a more plush ride and a more controlled feeling, while the revolutionary HPSD continues to give you the most responsive and best handling bike on the track—you’ll own the turns, and that’s where races are won.

Features
Rear Suspension - The rear suspension gets a new linkage to help give the CRF450R better handling and tracking, and a more balanced suspension performance. The fully adjustable Pro-Link® rear suspension sports an exclusive KYB® integrated reservoir, and a large 50mm rear shock damper for improved suspension action under the toughest riding conditions.
Batteryless Fuel Injection - The CRF450R was our first MX bike with fuel injection, and its always been the standard in the class. For 2011 weve made it even better, by giving it a new throttle body and new ECU programming for crisper throttle control and even easier starting.
Lightweight Aluminum Frame - The CRF450Rs race-inspired twin-spar aluminum frame revolutionized MX chassis tech when it first appeared in 1997 on the radical CR250R and has continued to do so every year since. Our latest frame boasts optimized torsional and lateral rigidity with minimized weight and maximum durability, ensuring razor-sharp handling performance. The updated subframe for 2011 takes the concept even further.
449cc Unicam® Engine
Works-Style Brakes - Hondas MX bikes have always had great brakes on the track, and the 2011 CRF450R continues that tradition. Discs front and rear with factory-spec master cylinders help haul you down fast, so you can outbrake the other guy into the turns.
Front Suspension - Kayaba front suspension features a sophisticated inverted Air-Oil Separated (AOS) system with an exclusive Honda 48mm-diameter fork, adjustability for rebound and compression damping, and 12.2" of travel. New-for-2011 settings match it up to the new rear suspension.
Honda Progressive Steering Damper - Weve taken the revolutionary HPSD and made it even better for 2011 by giving it a bigger 24mm piston. You get more damping when you need it, but the HPSD operation is still completely transparent when you dont.
94 dB Exhaust System - The CRF450Rs new silencer teams with the bikes revised fuel-injection throttle body and injector to help fatten up the low- and midrange

- The Class of the Open-Class MX Bikes: Honda CRF450R
Long regarded as the bike of choice in the big-bore motocross division, the 2011 CRF450R incorporates a host of improvements that will help this bike retain its standing as the yardstick by which all others in the class are compared. Various tweaks to the engine tuning broaden the already prodigious powerband-more low-end pull and midrange grunt-while also enhancing throttle response via a new throttle body.
In addition, revised suspension linkage and settings yield improved control, increased ride plushness and enhanced rear-wheel traction. A new Honda Progressive Steering Damper (HPSD) with a larger damper piston (24mm versus 20mm) produces even better tracking traits than before. In addition, the CRF450R now features a newly designed muffler that meets the sound levels of 94 decibels required by some racing organizations in 2011, making it competition-legal right off the showroom floor. All this and more make the 2011 CRF450R a shoo-in to maintain its dominant role among open-class MX bikes. MSRP $8,199. Available in Red beginning October 2010.
The Award-Winning Honda CRF250R Gets Better Yet in 2011
Despite winning numerous comparison tests and awards in 2010, the CRF250R enters the new season sporting a number of improvements that will help it continue its winning ways. A new Honda Progressive Steering Damper (HPSD) with a larger, 24mm damper piston aids tracking precision, and new suspension settings front and rear help give this stellar-handling machine even better chassis balance for 2011. Changes to engine tuning now give the CRF250R a stronger bottom-end and midrange hit, and this 2011 model features a new muffler that meets sound levels of 94 dB required by some racing organizations. MSRP $7,199. Available in Red beginning October 2010.
Family-Friendly CRF70F and CRF50F Return in 2011
In a completely different segment within the vast Honda spectrum, the family-friendly CRF70F and CRF50F return to the lineup in 2011. Featuring an automatic clutch, low seat height and a three-speed transmission, the CRF70F has long served as a practically perfect choice for beginning riders. Credit too the torquey 72cc air-cooled single-cylinder four-stroke engine that has grown to near-legendary status for reliability over the years. Likewise, for more than 40 years the CRF50F has introduced legions of riders the world over to the sport of motorcycling. It tips the scales at an unintimidating 110 pounds and the little CRF50F boasts a tough 49cc air-cooled single-cylinder four-stroke engine renown for its durability plus an ultra-low seat height, automatic clutch, three-speed transmission and an inverted fork. Both of these machines represent the fun that turns the dreams of beginning riders into trail-time reality. CRF50F MSRP $1,499; CRF70F $1,899. Both models available in Red beginning October 2010.
Options, Options and More Options: FourTrax Rancher Family
Year after year, more and more ATV riders come to sing the praises of the ready-and-willing FourTrax® Rancher®-and for good cause. This family of full-sized machines, assembled at Hondas plant in Timmonsville, SC, has proven many times over to be the most dependable partner you could ever hope for, whether the day calls for work or fun. At the heart of each Rancher beats a powerful liquid-cooled, fuel-injected 420cc engine with convenient electric starting and plenty of grunt for getting the toughest jobs done. From there, its a matter of choosing the features that best fit your riding needs, conditions and desires.
Many Rancher fans swear by the base model FourTrax Rancher with its automatic clutch and manual-shift five-speed transmission with reverse because its such a workhorse. Other owners are equally enamored of the FourTrax Rancher ES with its remarkable Electric Shift Program (ESP®) that shifts with consummate ease with the touch of a handlebar-mounted button. Others will allow that while these two-wheel-drive Ranchers are great, the addition of the four-wheel-drive option found in the manual-shift FourTrax Rancher 4x4 and the ESP-equipped FourTrax Rancher 4x4 ES with their easy-to use TraxLok® 4WD/2WD selector makes a good thing even better. And then there are those who love to opt for the top-tier models, and in this case that would be the automatic-transmission 4x4 FourTrax Rancher AT and FourTrax Rancher AT with Electric Power Steering. Both of these upscale models feature five-speed auto-shifting or push-button ESP shifting, plus four-wheel disc brakes and independent rear suspension.
Thats a lot of variations on one great theme, but no matter which model you select youll see why Hondas FourTrax Rancher has long remained a favorite. MSRP TBD. Two-wheel drive models available in Red and Olive; available early 2011. 4x4 models available in Red, Olive and Camo; available December 2010.
The TRX250X Offers Full-Sized Fun
In the sport ATV category, the TRX250X delivers full-sized ergonomics and its also full of great features including electric starting and Hondas innovative SportClutch™ that enables the rider to experience manual clutch actuation with the advantage of no stalling. That makes it easy to enjoy the plentiful power on tap and the five-speed transmission plus reverse for day-long adventuring. Its no wonder that the sporty and fun-to-ride TRX250X continues to stand out as a favorite among beginners as well as longtime riders, year after year. MSRP TBD. Available in Red and Black beginning September 2010.
