2009 Yamaha YFZ450R ATV

Yamaha YFZ450R


First Ride Review - From the United Arab Emirates:

While in the United Arab Emirates (more info - trip report), I had the opportunity to ride a new 2009 Yamaha YFZ450R in the dunes for a few days.  What a treat!

I own a Kawasaki KFX450R with long travel and some other goodies, so I am pretty familiar with 450 ATVs. My first impression after hopping on the 450R was that it felt right at home. It took just a short time to get comfortable and I was off.

Once in the dunes, I was pleasantly surprised with how nimble the 450R felt. Even with long travel suspension, it still felt very light and able to be tossed around. The extra width was really noticeable over a stock 450 and made the quad handle really well while cornering.

The stock YFZ450R has plenty of power for the dunes, even with the knobby tires.  The engine loves to rev up high and really pulls well.  Throw some of the GYTR hop-ups and a set of paddle tires on the YFZ450R and it will be quite the contender.

I was very happy with this ATV and would consider buying one if I was in the market.

2009 model year machine, built to be the world’s best all-around high performance racing and recreational sport ATV, comes loaded with state-of-the-art suspension, fuel injection, a no-weld aluminum frame and an all-new power packed engine set in a motocross-wide chassis.

The new YFZ450R meshes this history of dominance with the latest in Yamaha technology and innovation. In its stock form, the YFZ450R is the best all around performance ATV combining racing technology and features with all-terrain sport performance. Starting with its motocross track-width, the YFZ450R is immediately ready for the MX track. The no-weld cast aluminum frame is lightweight and has a tension-steel bottom portion that helps keep the engine as low as possible centralizing mass for excellent handling. The cast aluminum frame is bolted together, rather than welded, for maximum durability.

The YFZ450R comes with newly designed front and rear suspension. The front frame is narrow at the A-arm mounting points reducing changes in the camber as the A-arms travel through their full range of motion. The front 44mm KYB shocks have Kashima coating for smooth operation and impact absorption with 9.8 inches of wheel travel. The gravity-fed aluminum rear swingarm is matched to a fully adjustable 46mm KYB piggyback shock affording the rear wheels 11 inches of travel.

The YFZ450R has a powerful 5-valve DOHC liquid cooled single cylinder 449cc engine that uses the cylinder head and cylinder from the championship-winning YZ450F. The titanium five-valve cylinder head comes with camshafts designed just for this machine that hammers out superior low- to mid-range torque and pushes through to a high-revving, hole-shot grabbing top end.

The technologically advanced 450R is also equipped with electronic fuel injection featuring a 42mm Mikuni® throttle body, 12-hole Denso injector system and a Mitsubishi 32 bit ECU, which provides exceptional atomization of the fuel for maximum power, unrivaled throttle response and automatic altitude and temperature adjustment. The system also includes idle speed control for easy, reliable start-up. A stainless steel head pipe with a titanium heat shield and a new oval muffler provide maximum performance while keeping the YFZ450R well within current noise guidelines.

Yamaha Factory Racing experience led to a host of enhanced features on the YFZ450R. One benefit is race prep and service made simple. Body panels come off easily, and there is no need to remove the battery or other components to take off the fenders. The oil tank is integrated with the crankcase so it’s easier to service the engine.

The YFZ450R also boasts ProTaper® handlebars and all-new four-position adjustability. There are two sets of holes in the handlebar crown and eccentric clamps that allow the rider to choose between the standard setting, 10mm or 20mm forward, or 10mm back. A newly shaped thumb throttle lever delivers smooth throttle control requiring less effort and causing less fatigue. A new seat design is thin yet roomy in the front and wider and more padded in the back for a more comfortable all-around ride. The YFZ450R also comes with very large 65mm wide foot pegs with kick-ups that provide maximum traction and added comfort when moving around on the machine.

Newly designed Dunlop® tires have a superb combination of compound, tire profile, tread pattern and sidewall-to-tread center stiffness to provide outstanding comfort, bump absorption and precise cornering performance. At 20 inches in the rear and 21 inches in the front, the tires also provide maximum ground clearance for track, trail or dune riding. The YFZ450R has excellent stopping power from dual front hydraulic disc brakes and a lightweight wave-type rear rotor including dual piston calipers in the back as well as the front.

Rounding out the ATV’s top features is an instrument panel located on the fender in front of the rider including vital indicators signaling low fuel, coolant temperature, check engine, and neutral gear in a straightforward LED display. The 2009 YFZ450R comes in a standard color Team Yamaha Blue/White or in a second color Red/White.

MRSP of $7,999.
