Quieter. Faster. Better than ever.
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 model also features a new muffler that meets the 94-decibel sound level required by some racing organizations in 2011.

Are you a winner? Do you want to ride like one? Then you better get yourself on a 2011 CRF250R. We�ve given our quarter-liter wonder some serious upgrades for 2011 and it likes to win.

Because there�s a new 94dB exhaust rule this year, we gave the CRF250R a new muffler. But we also gave it a new ECU settings which, combined with the exhaust, gives you more usable power, especially in the midrange. It�s a win-win situation: A quieter bike and one that�s even easier to ride.

Like the CFR450R, we also gave the CRF250R a new Honda Progressive Steering Damper (HPSD) with a new, bigger 24mm piston. That gives you more damping when you need it, but still remains as transparent as ever when you don�t. Better handling, better balance, better tracking, especially at the limits of performance: the new 2011 CRF250R has it all.

The technology you need to win.
The CRF250R has won Transworld Motocross magazine�s �250 Four-Stroke MX Bike of the Year� not just once, but four straight years. Year after year, the CRF250R keeps leading the way, not only in terms of technology, but in terms of how rider-friendly this awesome bike is. Big changes in the exhaust system, new suspension settings, a bigger, better HPSD and more midrange power make the 2011 CRF250R the best 250 ever.

Light Makes Might.
Compact and batteryless, the CRF250R�s Programmed Fuel Injection (PGM-FI) system optimizes performance, and improves fuel efficiency.

Not just Quieter: Better.
The new muffler combines with a new subframe and numberplate. On a bike this refined, just slipping on a new silencer won�t get the job done.

The Power of One.
More compact and more power - it's all anyone could ask from their MX machine, and the CRF250R's Unicam� engine delivers. Big time.

Straighten Up and Fly Right.
We�ve upgraded the CRF250R�s Honda Progressive Steering Damper (HPSD) for 2011 with a bigger piston, ensuring even sharper cornering ability and straight-line handling.

2011 Honda CRF250R Features

New for 2011
�New engine tuning produces added response and midrange power production.
�Honda Progressive Steering Damper (HPSD) features larger piston diameter (20mm to 24mm) for improved tracking traits.
�Revised fork valving offers improved balance and bottoming resistance.
�New shock valving helps deliver optimum chassis balance and improved suspension action.
�Redesigned muffler lowers sound emissions to 94 dB.

Features
= 249cc Unicam� Engine
= Works-Style Front and Rear Brakes - Compact twin-piston front brake caliper, anodized-aluminum brake pistons and lightweight 240mm front disc increases stopping power while minimizing unsprung weight for improved turning and handling. HRC works-type rear brake system adds a 240mm brake rotor to its integrated rear master-cylinder and fluid reservoir, a set-up that eliminates the separate reservoir and hose.

= Batteryless Fuel Injection - Other fuel injection systems are heavy compared with the CRF250R's, which is light and compact � call it fuel injection done right.
= Twin Spar Aluminum Frame - The 2011 CRF250R boasts an HPSD-equipped twin-spar aluminum frame with a forged aluminum steering head. We even tweaked the subframe this year to work better with the new exhaust silencer.
= 94 dB Exhaust System - The CRF250R's new silencer teams with the bike's revised fuel-injection settings to help fatten up the low- and midrange.
= Honda Progressive Steering Damper - We've 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 don't.
