2008 Honda TRX450R:
Available in manual- and electric-start versions, the mighty TRX450R has won races in virtually every ATV racing arena as well as three victories in the grueling wilds of the Baja 1000.
New for 2008
New Black/Blue color joins White and Red on the TRX450ER.
Engine/Drivetrain
High-Performance Unicam® cylinder head design (see Technology Section)
Compact, lightweight engine designed specifically for ATV usage is worthy of its CRF® heritage.
Electric-start version features an electric starter that drives the clutch side of the crankshaft to provide superior lubrication of starter gears and to 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 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.
Maximum engine rpm is 9850.
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 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.
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.
Exhaust system and free-flowing muffler increase performance while maintaining low noise levels.
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 with low ratios designed to match engine power characteristics.
Transmission ratios designed for racing applications and trail use.
Chassis/Suspension
Rider's position features low 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, double A-arm front suspension with fully adjustable Showa shocks provide 8.4 inches of travel, and features rear-facing reservoirs for increased durability.
Pro-Link® Rear Suspension (see Technology Section) with fully adjustable Showa piggyback shock provides 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 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.

Ultra-rigid cast aluminum swingarm reduces weight and ensures optimal suspension action.
Titanium heat shield is super light and strong.
Long travel out back means an excellent ride and handling.
Eccentric chain adjuster mechanism simplifies that job, and a twin-piston rear brake caliper provides strong, controllable rear braking.
Numerous aluminum components—including the swingarm, upper A-arms, oil tank, grab bars and wheels—help keep overall dry weight down to a paltry 350 pounds.
Controlled Fill cast aluminum subframe is light and super-strong.
Lightweight front and rear master cylinders, combined with twin 161mm front discs with twin-piston calipers and single 200mm rear disc, deliver incredible stopping power with progressive control and feel.

CANAM DS 450

Just A Simple Promise: The Ride Says It All
Creating a sport ATV with the lowest weight, lowest unsprung weight, most mass centralization and the highest power challenged the Can-Am engineering teams in 2001. It was a no compromise approach that forced them to push the envelope, totally reinventing everything, from the frame and the engine, to the front and rear suspension systems. Six years later, the four challenges are mastered… Meet the all-new, race inspired Can-Am DS 450™!
