Sure, the TRX450ER makes huge horsepower. But it also handles with a confidence-inspiring predictability that lets you have fun with that power. Its 449 cc four-valve Unicam engine comes from the awesome CRF450X enduro bike, but it has been carefully adapted for ATV use with a special piston and camshaft and a heavy-duty clutch. To make sure you can put all that power to good use, the TRX450ER boasts a lightweight chassis with a racy cast-aluminum swingarm, double-wishbone front suspension with fully adjustable Showa shocks, and powerful, predictable disc brakes front and rear.
Powerful four-stroke 450cc liquid-cooled four-valve Unicam engine is based on the awesome CRF450X off-road engine.
Unicam valve train provides the light weight of a compact single-cam drive and the optimum combustion chamber shape for maximum power at all engine rpm.
Unicam valve train features a carburized single camshaft that directly actuates two 36mm titanium intake valves. The camshaft exhaust lobe actuates two 30mm steel exhaust valves via a forked, low-friction roller rocker-arm.
Electric starter drives the clutch side of the crankshaft to provide superior lubrication of starter gears, and produce a narrow engine with a short, strong crankshaft.
Lightweight, compact, internal auto decompressor provides superb cold-starting and hot-starting operation.
Crankshaft is made of high-strength, low-carbon steel with carburized main journals for maximum durability at sustained high-rpm operation.
Cylinder head cover is made of magnesium to reduce engine weight.
Forged three-ring, 12.0:1 compression, slipper piston is lighter than a conventional design, revving quickly while maintaining excellent cylinder sealing and high-rpm power.
Double-carburized connecting rod utilizes a big-end needle bearing for maximum high-rpm performance and durability.
Nikasil cylinder lining is lightweight and provides cooler and quieter operation for extended engine life.
Press-fitted steel sparkplug pipe fits between forked exhaust rocker arms, further contributing to compact cylinder head design.
40mm Keihin FCR-type carburetor features four rollers on the flat slide, resulting in very light throttle effort, smooth operation, crisp throttle response and excellent rideability.
Carburetor features a throttle position sensor (TPS) that helps maintain linear response throughout the rpm range.
Twin-sump lubrication system separates the oil supply for the crankshaft, piston and valve train from the clutch and transmission. This ensures a cool supply of oil to the clutch, eliminates clutch and transmission material contamination of the engine oil, and reduces the amount of circulating oil and the required size of the oil pump.
Vertically split crankcases feature a built-in oil pump, reducing weight compared to a conventional design.
Left side countershaft bearing and axle carrier feature double-row bearings for added durability.
Exhaust system uses a lightweight stainless steel header and muffler.
Radiator is lighter weight and has revised fin pitch for improved airflow in all riding conditions.
Compact, flat radiator fan is lightweight and provides efficient cooling.
Gear-driven balancer reduces vibration and drives the water pump. Eight clutch plates provide the surface area necessary to handle the engine's massive torque.
Durable five-speed transmission.
Round-tube steel frame with removable aluminum subframe is lightweight and durable.
One-piece cast aluminum swingarm for light weight, maximum strength and durability.
Independent double-wishbone front suspension with fully adjustable Showa shocks provides 213mm (8.4 inches) of travel, and features rear-facing reservoirs for increased durability.
Pro-Link rear suspension with fully adjustable Showa piggyback shock provides 237mm (9.3 inches) of travel.
Dual 174mm front disc brakes with twin-piston calipers and high-pressure front brake lines provide excellent stopping power.
190mm rear disc and beefy single-piston caliper.
Removable aluminum rear grabrail and front bumper to help keep weight low.
Lightweight aluminum wheels reduce unsprung weight for outstanding handling.
Dunlop radial tires provide superb traction and cornering ability.
Durable and lightweight O-ring-sealed drive chain.
Throttle lever and carburetor feature full-closed detection system.
Engine design meets California Air Resources Board (CARB) off-road emissions standards.
Convenient oil-level window allows for at-a-glance oil check.
Long, narrow seat is designed for superior comfort and performance in all operating conditions. Saddle is also easy to remove for convenient access to the air filter.
Adjustable dual headlights with 30-watt bulbs and large reflectors for excellent visibility and distinctive appearance.
Pivot-access brake calipers for easy pad replacement.
Engine cases protected by high-impact plastic skidplate.
LED tail/brake light for light weight and aggressive appearance.
CRF-style clutch and front brake lever.
Wide footpegs for superior rider control.
Aluminum shift and brake pedals.
CRF-type handlebar grips.
Honda Racing-inspired colours and graphics.
Optional HRC Racing Kit available.
