Where do you go when you want a four-wheeler that's not just all work and no play? Look no further than the TRX450ER.

ENGINE/DRIVETRAIN

• Powerful four-stroke 450cc liquid-cooled four-valve Unicam engine is based on the award-winning CRF450R and CRF450X engines
• Compact, lightweight engine designed specifically for ATV usage is worthy of its CRF heritage
• 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 carburised 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
• The TRX450ER features an electric starter that 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
• Kickstart version incorporates ATV-type forward kickstarting for ease of starting and light weight
• Crankshaft is made of high-strength, low-carbon steel with carburised 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-carburised 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 spark plug 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 to the engine oil, and reduces the amount of circulating oil and the required size of the oil pump
• 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 air flow 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

CHASSIS/SUSPENSION

• New rider’s position features 8mm lower handlebar, seat and footpegs for improved center of gravity and rider feel
• 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 213 mm of travel, and features rear-facing reservoirs for increased durability
• Dual 174mm front disc brakes with twin-piston calipers and new high-pressure front brake lines provide excellent stopping power
• 190mm rear disc and beefy single-piston caliper provide improved stopping power and increased ground clearance
• Aluminum brake calipers and brackets front and rear reduce weight
• Removable aluminum rear grabrail and front bumper for reduced weight
• 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
• Pro-Link rear suspension with fully adjustable Showa piggyback shock provides 236 mm of travel

ADDITIONAL FEATURES

• 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 improved 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 improved rider control
• Aluminum shift and brake pedals
• CRF-type handlebar grips
• Honda Racing-inspired colors and graphics
• Optional HRC Racing Kit available
• Transferable six-month limited warranty
