2009 Honda CRF450R

In the all-new and lighter 2009 CRF450R, a brand-new engine salt away electronic fuel injection, developed concurrently with an entirely greater rolling chassis, power together to effect 450-class-leading power along with 250-style handling. It's an unprecedented blend of power, suspension again handling that enlightened bring a genuine rotation to the premier motocross comeliness.



Features & Benefits

New for 2009
· replete innumerable lighter engine

· Programmed Fuel Injection (PGM-FI)

· All-new fifth generation aluminum body features a longer abandon arm, and a secondary CG since sophisticated acceleration further better panorama wheel traction

· Kayaba exhibit besides constitute suspension

· all greater bodywork



Engine/Drivetrain
· All-new engine spins faster-11,450 rpm-and harder, churning outermost 56.3 bhp at 8500 rpm and 37.5 lb./ft. of torque at 7000 rpm.

· Liquid-cooled four-valve Unicam® 449cc engine produces more than 125.3 hp per liter and now utilizes a four-lobe camshaft and individual rocker arms being each exhaust valve to reduce regimentation and stimulate to higher rpm ceiling.

· Engine completely redesigned to lower the overall height and position it closer to front wheel, resulting in a lower overall Cg and better check lineup for sophisticated handling.

· Engine height reduced by shortening length of connecting rest 3.5mm (105.6 to 102.1mm) to allow shorter cylinder.

· Relocated crankshaft main journal cradles (inside of flywheels) allows reduction of connecting rod big-end diameter (34 to 33mm), reducing control while maintaining overall strength. Crankshaft cutaway eliminates piston skirt inwardness at BDC, also reducing weight.

· Reshaped cylinder head hot spot foyer is shorter in conclusion has a larger volume squish corner for better flame propagation.

· Lightweight titanium intake valves
and redesigned valve springs weaken overall engine eminence and permit higher rpm. aggrandized intake valve stem diameters reduced (5.5 to 5.0mm).

· Lower camshaft mount built into the cylinder commander to reduce charge and appliance height.

· Cam sprocket because press-fitted to camshaft, reducing qualification by 20 grams compared to previous bolted design.

· Cylinder attaches to engines cases with through-bolts instead of studs, allowing moment constitution cylinder removal.

· further forged slipper-piston fabric permits thinner crown, contributing to shorter conduit height. Low-friction surface treatment assures high-rev potential.

· Lightweight Ni-SiC cylinder packing provides cooler and quieter operation for extended appliance life.

· Redesigned auto decompression again hot restart manner is simplified and lighter secrete cam-integrated plunger further shaft-integrated decompression weight for plain starting in hot or cold conditions.

· All-new Programmed Fuel Injection system (PGM-FI) utilizes a 50mm throttle body dream up with 12-hole injection nozzle fed by lightweight 50-psi pump to ensure optimum fuel atomization and absolutely targeted fuel charge. figure also achieves an improvement in fuel consumption.

· PGM-FI system monitors throttle position, intake disposition and coolant temperatures, mind-set pressure and gear view to accurately map fuel charge and ignition spark, significantly improving partial-throttle response and chip assure excellent rideability.

· AC generator elongated to benefit PGM-FI outline. Two crankshaft position sensors quickly determine handgrip say so to make safe quick starts, unstable or cold.

· Twin-sump lubrication system separates the oil transfer for the crankshaft, piston and valve dominate from the clutch again transmission. This ensures a cool supply of oil to the clutch, eliminates clutch again transmission material contamination of the engine oil and reduces the numeral of circulating oil allowing the oil pump size to be reduced.

· Redesigned exhaust system incorporates a left-side pipe captain exhaust port, increasing header length further allows neckerchief to body positioned closer to center of mass, contributing to significantly improved oversight aligning and handling.

· Gear-driven balancer reduces quiver and drives the bedew pump.

· New mechanical moisten pump seal improves durability.

· Coolant action rerouted facade appliance cases via bolt-on flange/jacket, allowing abbreviation of crankcase and cylinder width, and overall weight.

· Oil pump strainer now built recreation the engine case to reduce parts also weight.

· Eight clutch plates handle the engine's massive torque while the number of clutch springs is reduced from 6 to 4. This reduces centrifugal weight, allowing the engine rev quicker.

· Kashima coating applied to the clutch basket, clutch center and tribulation plate correct clutch happening further clutch feel.

· extended transmission modifications narrow transmission diameter and reduce power forfeit sacrificing durability.



Chassis/Suspension
· Fifth-generation Twin-Spar Aluminum Frame harbour forged-aluminum steering head is now 14 ounces lighter than previous design. Spar alp was in want (70 to 66mm) and width was narrowed (27 to 26mm). Stronger downtubes improve front-end feel.

· Steering going and overall usefulness were improved by moving pilotage head pipe ferry 10mm (and closer to swingarm pivot).. Positioning the front circle 15mm farther back again closer to crankshaft.

· Swingarm is 18mm longer for improved traction.
Frame, manoeuvring head and swingarm modifications buy into a abridgement in triple weld offset (22 to 20mm).

· Swingarm cross-member wall thickness was flat (3.75 to 3.0mm) to stack weight.

· assumed swingarm pivot plates increase rigidity now improved handling.

· Lower machine build rails are widened and beveled to protect greater cornering clearance.

· Removable rear subframe was redesigned to eliminate brackets and cross-members. Shape altered to more appropriate mindset filter access and narrow the bike profile.

· Honda Progressive Steering Damper (HPSD) revalved for more linear damping. HPSD attributes a compact damper affectionate to the lower triple clamp and the guidance head to allow further aggressive steering characteristics and assist straight-line account. Damping action smoothly progresses as handlebar deflection increases, which produces inordinately natural guidance characteristics and feel.

· Front and rear wheels plane HRC works-type lightweight aluminum spoke nipples.

· manifestation wheel featuring in addition stiffer axle collar provides excellent rigidity.

· Rear pivot diameter of 25mm and large-diameter bearings assure additional rigidity. Axle parapet thickness reduced (2.5 to 2.2mm) to save weight (38 grams) while axle collar is strengthened for sophisticated rigidity.

· Revised, more select Inverted Air-Oil-Separated (AOS) fork features exclusive Honda 48mm diameter fork made by Kayaba hold back all-new damping further spring settings.

· Pro-Link Rear Suspension make-up exclusive Kayaba integrated reservoir blot out all-new damping and loom settings.

· Large 50mm rear shock damper piston thickness for consistent performance under demanding riding conditions.

· HRC works-style rear brake cut integrates the rear master-cylinder and fluid reservoir, eliminating the separate reservoir also hose.

· Link-type show brake master drainpipe and a lightweight brake rotor provide strong braking.

· Re-shaped big idea style 240mm front brake rotor is 1.3 ounces lighter. Front disc guard is smaller, lighter further vented.

· 240mm effect brake rotor features works style pattern also is 1 ounce lighter. New plastic tape guard saves 4 grams of weight.


Additional Features
· Honda First: Engine stop switch features an integrated LED pre-ride buy indicator with EFI characteristic capability to ensure CRF450R is operating at maximum capacity.

· another grey color magnesium head cover, clutch cover besides left side cover.

· Clutch cover profile reshaped for improved foot placement.

· Left side oil check dip-stick replaces sight glass.

· Redesigned higher-capacity airbox improves filter access.

· New sidecover body is narrower also improves flow to airbox.

· Redesigned radiator shrouds are narrowed to aid rider movement.
