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 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.
Engine stop switch features an integrated LED pre-ride check indicator. This confirms the PGM-FI system is operating normally.
