New for the 2006 Yamaha YZ450F

Postby 4Strokes » Mon Dec 04, 2017 1:21 pm

What's New for the 2006 Yamaha YZ450F
New, close-ratio five-speed transmission provides more performance in a wider range of riding environments.

All-new aluminum frame is an extensively tested combination of castings, extrusions, forgings and aluminum tubing -- all carefully put together to produce a chassis that takes legendary YZ handling to the next level.

Speed-Sensitive System 48mm Kayaba fork move the TCV (transfer control valves) above the fork springs, so that damping force is now controlled by piston speed; that prevents mid-stroke damping force changes, for a smoother, more precise ride.

Titanium-sprung four-way adjustable rear shock rod diameter is 2mm bigger. New, Kashima coating reduces friction for fantastic compliance and great handling.

Carburetion and exhaust changes let the 449cc four-stroke breathe free for even greater power production.

Changing the cylinder head angle and moving the dry sump oil tank inside the front of the crankcase improves overall balance and handling and eliminates external oil lines.

Redesigned piston, crankshaft and connecting rod for increased performance and durability. An oil jet now directs oil at the piston bottom for increased cooling.

Trick new bits include a light, strong ProTaper aluminum handlebar in adjustable clamps and a trick new exhaust system.

A special 50th anniversary model.

50th Anniversary Celebration at Unadilla

50th Anniversary Celebration at Unadilla
Yamaha Factory MX Team to Celebrate 50th Anniversary at Unadilla
In celebration of its 50th anniversary, the Yamaha Factory Motocross Team's stable of YZ450Fs will feature the yellow and black retro colors that graced many past Yamaha champion machines. Conjuring up images of Ricky Johnson, Mike Bell, Ron Lechien, Rick Burgett, Broc Glover, Gary Jones, Pierre Karsmakers and Marty Moates, the tribute to the 50th anniversary makes its exclusive appearance at the Unadilla National July 17, 2005.

Who could forget one of the most recognized photographs of all time when Bob "The Hurricane" Hannah was launched, with feet and legs completely off his bike, out of infamous Gravity Cavity on his Yamaha? Motocross enthusiasts will enjoy a race down memory lane as Team Yamaha will once again circulate the infamous Unadilla circuit on yellow and black YZs.

"Yamaha recently introduced the Limited Edition Yellow and Black 2006 YZ450F and the response was overwhelming" explains Yamaha's Terry Beal. "The Factory boys couldn't wait until 2006 to race the yellow/black so Unadilla, with its racing heritage, became the perfect backdrop for the Factory Team this year."
