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.
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.

CRF450R
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 Honda Progressive Steering Damper (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.
New for 2011
- Revised engine tuning and new 46mm throttle body increase low-end and midrange power and give improved throttle response.
- Front fork features a lighter cartridge cylinder and all-new valving for improved control and increased ride plushness.
- Revised shock valving yields improved control and increased rear wheel traction.
- New suspension linkage produces improved chassis balance and increased rear wheel traction in rough-track conditions.
- Honda Progressive Steering Damper (HPSD) features larger piston diameter (20mm to 24mm) for improved tracking traits.
- Redesigned muffler lowers sound emissions to 94 dB.
