Here's the latest info from Honda on the new 2011 CRF250R and CRF450R. This year looks like a bit of a refinement year, rather than wholesale revolution, but making the big CRFs better is always a chore. you guys,wanna see some pics of the new 2011 hondas? if yes,click on the link below. http://www.vitalmx.com/photos/features/2011-Honda-CRF250R-and-CRF450R,35639/2011-Honda-CRF450R,37259/GuyB,64 2011 Honda 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. Model: CRF450R Engine Type: 449cc liquid-cooled single-cylinder four-stroke Bore and Stroke: 96mm x 62.1mm Compression ratio: 12.0:1 Valve Train: Unicam, four-valve; 36mm intake, titanium; 30mm exhaust, steel Induction: PGM-FI, 50mm throttle body Ignition: Full transistor with electronic advance Transmission: Close-ratio five-speed Final Drive: #520 chain; 13T/48T Suspension Front: 48mm inverted KYB Air-Oil-Separate (AOS) with rebound and compression damping adjustability; 12.2 inches travel Rear: Pro-Link KYB single shock with spring preload, rebound damping adjustability, and compression damping adjustment separated into low-speed and high-speed; 12.5 inches travel Brakes Front: Single 240mm disc with twin-piston caliper Rear: Single 240mm disc Tires Front: 80/100-21 Rear: 120/80-19 Wheelbase: 58.7 inches Rake (Caster angle): 26° 54' Trail: 114.5mm (4.5 inches) Seat Height: 37.6 inches Ground Clearance: 13.1 inches Fuel Capacity: 1.5 gallons Color: Red 2011 Honda CRF250R  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. * Redesigned muffler lowers sound emissions to 94 dB. Model: CRF250R Engine Type: 249cc liquid-cooled single-cylinder four-stroke Bore and Stroke: 76.8mm x 53.8mm Compression ratio: 13.2:1 Valve Train: Unicam, four-valve; 30.5mm intake, titanium; 25mm exhaust, steel Induction: PGM-FI, 50mm throttle body Ignition: Full transistor with electronic advance Transmission: Close-ratio five-speed Final Drive: #520 chain; 13T/49T Suspension Front: 48mm inverted Showa 16-position rebound and 16-position compression damping adjustability; 12.2 inches travel Rear: Pro-Link Showa single shock with spring preload, 17-position rebound damping adjustability, and compression damping adjustment separated into low-speed (13 positions) and high-speed (3.5 turns); 12.5 inches travel Brakes Front: Single 240mm disc with twin-piston caliper Rear: Single 240mm disc Tires Front: Dunlop 742FA 80/100-21 Rear: Dunlop D756 100/90-19 Wheelbase: 58.6 inches Rake (Caster Angle): 27° 12' Trail: 117mm (4.6 inches) Seat Height: 37.6 inches Ground Clearance: 12.8 inches Fuel Capacity: 1.5 gallons Color: Red |
