First Look at Honda’s Fuel-Injected CRF250R!!

2010 HONDA CRF250R!
Fuel-injected•Single exhaust•All-new engine•All-new Frame!!

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.


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.


• 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.


• 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.
