TRX450ER |
Available in manual - and electric-start
versions, the mighty TRX450R has won races in
virtually every ATV racing arena as well as four
victories in the grueling Baja 1000.
New for 2009
- New White with Orange frame 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.
- Light-weight radiator with fin pitch designed
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 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.

subframe is lightweight and durable.

shock provides 9.3 inches of travel.

calipers and high-pressure front brake lines
provide excellent stopping power.

caliper provide improved stopping power and
increased ground clearance.

rear reduce weight.
