Feature of HONDA CRF250R (2010)
The CRF250R. All-new. And dominant as ever.Boasting an all-new, more powerful, more compact engine with Programmed Fuel Injection (PGM-FI) combined with an all-new Twin Spar Aluminum Frame featuring the Honda Progressive Steering Damper (HPSD), the 2010 CRF250R continues Honda’s long-standing position of class dominance. This latest CRF250R sets a higher benchmark for impressive power and class-leading handling all rolled into one competition-ready package.
To be the best you can be, you must never stop improving. That's why the Honda CRF250R has been re-thought, redesigned and re-engineered from the dirt up for 2010. Check out the new Unicam™ engine with a lightweight, battery-less PGM-FI fuel-injection system, the narrower aluminum frame with integrated Honda Progressive Steering Damper (HPSD), the all-new exclusive Showa front and rear suspension, and the more durable and higher-performing components almost everywhere you look. The 2010 CRF250R: Setting the bar just that much higher.
New for 2010
= All-new, more compact engine.
= Programmed Fuel Injection (PGM-FI).
= Progressive Steering Damper (HPSD)-equipped aluminum frame
= All-new front and rear suspension, featuring upper and lower fork tubes and a shock body developed exclusively for the CRF250R chassis.
= Redesigned higher-capacity airbox for enhanced breathing and increased power also improves filter access.
= All-new single-muffler exhaust system improves mass centralization.
= All-new bodywork.
Features/Benefits
Engine/Drivetrain
= All-new compact engine.
= Liquid-cooled four-valve Unicam® 249cc engine.
= Engine completely redesigned for improved power delivery from a significantly more compact package that lowers the center of gravity and enhances mass centralization for improved handling.
= New forged slipper-piston material permits a thinner crown. Low-friction surface treatment ensures high-rev potential.
= All-new Programmed Fuel Injection system (PGM-FI) utilizes a 50mm throttle body with 12-hole injector fed by lightweight 50-psi pump to ensure optimum fuel atomization and precisely targeted fuel charge. System also improves fuel consumption.
= PGM-FI system monitors throttle position, intake air and coolant temperatures and manifold pressure to accurately map fuel charge and ignition spark, significantly improving partial-throttle response and helping to ensure excellent rideability.
= AC generator enlarged to service the PGM-FI system. Two crankshaft position sensors quickly determine crank position to provide quick starts, hot or cold.
= New mechanical water pump seal improves durability
= Kashima coating applied to the clutch basket and clutch center improves clutch life and feel.
= All-new transmission ratios match engine power output.
Chassis/Suspension
= All-new HPSD-equipped Twin-Spar Aluminum Frame with forged-aluminum steering head. Spar height was reduced (70mm to 66mm) and width was narrowed (27mm to 26mm). Stronger downtubes improve front-end feel.
= Steering response and overall handling were improved by positioning the front wheel 15mm farther back and closer to the crankshaft.
= Frame, steering head and swingarm modifications permit a reduction in triple-clamp offset (22mm to 20mm).
= Removable rear subframe was redesigned to eliminate brackets. Shape altered to improve air filter access and narrow the bike profile.
= HPSD features a compact damper attached to the lower triple clamp and the steering head to allow more aggressive steering characteristics and assist straight-line handling. Damping action smoothly progresses as handlebar deflection increases, which produces very natural steering characteristics and feel.
= Pro-Link® Rear Suspension features exclusive Showa integrated reservoir with all-new damping and spring settings.
= Brake system integrates the rear master-cylinder and fluid reservoir, eliminating the separate reservoir and hose.
= Link-type front-brake master cylinder and a lightweight brake rotor provide strong braking.
Additional Features
= Engine stop switch features an integrated LED pre-ride check indicator. This confirms the PGM-FI system is operating normally.
= All-new higher-capacity airbox improves filter access.
= PGM-FI tuning connectors located behind radiator shroud for easier access
= Redesigned larger radiators, improve cooling performance
= New fuel-tank tether eliminates need to disconnect fuel line to work on top end.
= Rider ergonomics are optimized by adapting the handlebar, seat and footpeg height to place the rider's legs at the narrowest part of the frame for improved comfort and handling feel.
= Adjustable front-brake lever for improved control.
= Quick-adjust clutch perch for easy cable adjustment.
= Aluminum Renthal handlebar (971 bend) is rubber-mounted to help reduce rider fatigue and improve comfort.
New HRC settings kit, developed from long years of racing experience, provides an easy-to-use programming system with precise data for setting up the machine to meet all race situations. Ignition timing and fuel mapping settings can be uploaded by connecting the motorcycle to a computer and following simple step-by-step instructions. The system radically simplifies the setup process and makes tuning accessible to a wide spectrum of riders. Connection is simple with only one connector and no need to remove the fuel tank.
Press Release
Honda's New CRF250R Takes Lead From Big Brother
13 July 2009 - Honda's 2010 CRF250R sets a higher benchmark than ever for impressive power and class-leading handling all rolled into one competition-ready package.
Honda didn't have to look far for inspiration, adapting many of the same cutting-edge features found on the Pro Open class-leading CRF450R.
Boasting an all-new, more powerful, more compact engine with Programmed Fuel Injection (PGM-FI) combined with an all-new Twin Spar Aluminum Frame featuring the Honda Progressive Steering Damper (HPSD), the 2010 CRF250R continues Honda's long-standing position of class dominance.
Its lighter weight, more potent liquid-cooled four-valve Unicam engine sports new forged slipper-piston material that permits a thinner crown. Low-friction surface treatment ensures high-rev potential, whilst the PGM-FI system ensures optimum performance and improved fuel consumption.
Overall, the changes to the engine incorporate an automatic variation of fuel flow and ignition timing depending on conditions, whilst gear ratios have also been revised to suit the overhauled engine. The bike also incorporates larger radiators as well as more durable pistons and valves.
An all-new single-pipe exhaust system design moves the muffler closer to the bike's centre of mass, improving weight distribution and handling.
Its longer swingarm also improves stability as does larger diameter front forks and a lighter repositioned rear shock.
In addition to all-new bodywork borrowed from the CRF450R, Honda's smaller motocrosser offers improved steering response and overall handling via a repositioned front wheel.
The new CRF250R will be released toward the end of the year
Topping the list of exciting news is the 2010 CRF250R motocrosser. Boasting an all-new, more powerful, more compact engine with electronic fuel injection and an all-new twin spar aluminum frame with the Honda Progressive Steering Damper (HPSD), the 2010 CRF250R continues Honda's long-standing position of class dominance. This latest CRF250R sets a higher benchmark for impressive power and class-leading handling all rolled into one competition-ready package. Available in Red. In dealerships September 2009. MSRP: $7,199.00
