2007 Yamaha YZ450F |
|
|
|
|
|
| |
|
From The Manufacturer: |
|
- For 2007, the bike that started the four-stroke
revolution benefits from significant chassis and engine refinements that
ensure the five-titanium-valved YZ450F remains at the head of the
open-class pack.
- Modifications to the light and strong aluminum
frame and suspension mean light, precise, confident handling at any speed.
- Five-speed gearbox provides maximum flexibility
and the right gear for a wide range of riding environments.
- Ready to race straight out of the crate - with a
ProTaper aluminum handlebar in adjustable clamps, titanium shock spring,
ti footpegs, gripper seat, etc.
|
- Replacing the upper cast triple clamp with a light
and strong forging, slightly reducing steering head rigidity, and the use
of lighter outer fork tubes; lighter wheel rims and light wave-type brake
rotors add up to super-accurate, super-responsive steering.
- Increasing the length of the rear shock by 1.5mm
provides sharp handling. Replacing steel damping adjusters with aluminum
ones removes even more weight from the four-way adjustable,
titanium-sprung rear suspension unit.
- A more rigid clutch pressure plate helps put power
to the ground and dissipates heat more efficiently, especially during
partial-clutch operation. Shorter lever stroke with 12-percent reduced
effort means instant response.
- New, titanium exhaust pipe fattens low- and
mid-range power while simultaneously adhering to 2007 AMA noise
regulations.
- This year's ProTaper aluminum handlebar bend
raises the grips 8mm for an expanded cockpit. Forged bar clamps reduce
weight for superior handling.
|
- 449cc five-valve DOHC liquid-cooled engine is
super-powerful yet tractable.
- 39mm Keihin FCR flat-slide carburetor with
throttle position sensor (TPS) and leak jet delivers precise fuel/air
mixture and instant throttle response.
- Revised CDI ignition keeps that amazingly broad
and deep powerband hard-hitting, yet controllable.
- Lightweight, titanium valves and load-reduced
springs minimize reciprocating mass for fast-revving, hard-hitting power
delivery across the rev range.
- Additional weight-saving engine features include:
small-design cam chain tensioner and oil pump, aluminum oil hose,
all-titanium exhaust header, flange, bracket and heat shield and light CDI
ignition unit.
- Primary kickstarting with automatic decompression
and convenient handlebar-mounted hot start lever ensures easy restarts.
- Kick pinion gear is separate from the primary
driven gear for smoother clutch engagement.
- Large-capacity radiator is reinforced for greater
strength.
|
- Aluminum frame uses a mix of alloy casting,
forgings and extrusions to produce a tuned-flex frame that makes the YZ
the finest handling motocross bike ever.
- Speed-Sensitive System 48mm Kayaba fork places
transfer control valves (TCV) above the fork springs, so that damping
force is controlled by piston speed; Eliminating mid-stroke damping force
changes provides a smooth, precise ride.
- Titanium-sprung four-way adjustable rear shock
with Kashina-coated internals reduces friction for fantastic compliance
and great handling.
- More weight savings come via two-piece (part
aluminum, part plastic) engine protector plates and thin-walled engine
guard construction.
- Removable aluminum rear subframe constructed of
square-section tubing for light weight and easy maintenance - lighter
fasteners for 2007 enhance weight distribution and handling.
- Lightweight front wheel hub for reduced unsprung
weight and increased durability.
- Premium Dunlop knobbies provide unbeatable,
competition-spec traction and great wear.
- Lightweight 21-inch front and 19-inch rear Excel
rims are exceptionally durable and reduce unsprung weight.
|
- “Gripper” style seat cover gives excellent feel
and control, and the seat is lighter for 2007.
- Wide, cleated, folding titanium footpegs are
light, strong, and provide excellent comfort, grip and ground clearance.
- Works-style clutch lever features oversize barrel
adjuster for easy, on-the-fly adjustability of lever/cable play.
- Cleated rear brake lever and folding shift lever
tip offer superb grip and excellent durability.
- Repackable exhaust silencer.
- Durable, comfortable handlebar grips.
- Stainless steel clutch cable for longer life.
