Yamaha Announces the All-New, Highly Anticipated YFZ450R
Yamaha Engineering and Race-Ready Features Create New Top Level of Performance
MSRP for the YFZ 450R is $7999
LAS VEGAS, Nev. – September 8, 2008 – Yamaha Motor Corp., U.S.A., announced the highly anticipated and all-new YFZ450R at its national dealer meeting in Las Vegas today. The new 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.
HISTORY OF DOMINANCE
Yamaha has a well deserved reputation of building the industry’s best sport ATVs. The original YFZ450 was announced in 2003 as the first race-ready 450-class ATV with leading technology and more pure sport performance than any machine ever built at that time. Since then Yamaha has dominated the field across the board with the best selling big bore sport ATV in the Raptor 700R* down to the best selling 250-class machine with the Raptor 250. But the YFZ is still the pinnacle of ATV performance, and even with a constantly growing number of competitors entering the 450 market, the YFZ has always been the top seller in its class*.
MX WIDTH WITH CAST ALUMINUM FRAME
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.
SUPERIOR SUSPENSION
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.
POWERFUL 449CC ENGINE WITH FUEL INJECTION
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.
ADJUSTABLE HANDLEBARS AND SIMPLE SERVICE ACCESS
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 TIRES, DISC BRAKES AND RIDER COMFORT
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. It will be in dealerships in November with an MRSP of $7,999.

In ATV motocross, great power output doesn’t mean much without superior handling. YFZ450R delivers! Nearly three inches wider overall than the YFZ450, the stance of this new 450R is motocross-ready. The frame is designed of lightweight aluminum, with a tension-steel bottom frame that lets the engine sit lower for excellent mass centralization. Suspension components have more travel carefully chosen for best performance, and the front shock bodies feature Kashima coating for even smoother operation.
Fatigue can sometimes be a racer’s worst competition. That’s why the YFZ450R’s designers made this ATV so comfortable. It’s much roomier, with plenty of room to hang off in the corners, and the seat is padded just right to be more comfortable regardless of riding position. Handlebars are 4-position adjustable, too, so every rider can choose the best position, and the throttle has been designed for all day comfort. What’s more, the engine balancer has been revised to even further reduce vibration.
This 449cc engine uses the cylinder head and cylinder from the championship-winning YZ450 for awesome power output. That means titanium five-valve cylinder head technology, with a camshaft designed just for this machine to deliver abundant low to midrange torque for performance where you can really use it to take the lead – while still maintaining a super strong top end to let you pull away from the pack.
The YFZ450R adopts fuel injection for precise fuel delivery. With big 42mm Mikuni® throttle body and 12-hole injector, this system provides exceptional atomization of the fuel for maximum power. The system also includes ISC (Idle Speed Control) for easy, reliable start-up and warming.
This ATV is designed to make race prep easy. Body panels come off easily for service; there’s no need to remove the battery or other components to get the fenders off. The aluminum frame is bolted together, rather than welded, for maximum durability. And the oil tank is integrated with the crankcase so it’s easier to service the engine.
Engine:
The fuel-injected 449cc engine uses the cylinder head and cylinder from the YZ450 for superb power characteristics. Power deliver is smooth and strong off the line with lots of low and mid range where you need it. As rpm climbs you’ll find the same top end punch that has made the YFZ450 such a fierce competitor and class leader.
The new crankcase holds the newly designed crankshaft that’s ready to handle the increased torque output, as well as the counterbalancer that has an increased ratio for superior vibration control. The crankcase also houses the oil tank, which helps to centralize mass for unmatched handling and makes maintenance easier.
Camshafts are all new for this model, and are designed to maximize the torque available in the low and mid ranges.
Fuel injection uses a 12-hole injector that provides exceptional atomization of the fuel for maximum combustion efficiency and power delivery. The system also uses a big, 42mm Mikuni® throttle body and includes ISC (Idle Speed Control) for easy, reliable start-up and warming.
Chassis/Suspension:
The chassis is very spacious, allowing room for an aggressive racer to move around during the moto, and the ATV’s body panels that the rider contacts during operation are of a special, softer plastic material for greater comfort. And the seat is narrow in the front, yet wide and padded in the rear to provide a more comfortable ride, even when hanging off on the side of the seat in a turn.
Wheels are set motocross-spec wide, near the maximum allowable 50 inches, for great cornering ability.
The newly designed Dunlop® front tires have a superb combination of the right compound, tire profile, tread pattern, and sidewall-to-tread-center-stiffness ratio to provide outstanding comfort, bump absorption, and precise cornering performance. The rear Dunlop® tires also help the rider achieve a high level of performance with superb feedback in turns and great grip on the turn exit. At 20 inches in the rear and 21 inches in the front, the tires also provide much better ground clearance than the competition. That makes the YFZ450R fun to ride off-road, too.
ProTaper® handlebars are mounted on 4-way clamps for exceptional adjustability. There are two sets of holes in the handlebar crown, and eccentric clamps so the rider can choose the standard setting, 10mm or 20mm forward, or 10mm back.
Foot pegs are a huge 65mm wide, something riders will appreciate every time they want to get up on the pegs, with good kick-up on the ends for solid footing.
The all-new frame is aluminum for lightweight, except for the frame member under the engine. Here tensioned steel is used for its combination of strength and thinness. This allowed the designers to sit the engine lower overall for excellent mass centralization for unmatched handling.
The front frame is noticeably narrow at the A-arm mounting points. This dramatically reduces changes in camber as the long A-arms travel through their full range of motion. The front 44mm KYB shocks have Kashima coating for smooth operation with superb bump absorption and excellent anti-bottoming characteristics. The 10.4 inches of wheel travel means this racer is up to even the most challenging tracks.
The rear swingarm is crafted of strong, gravity-fed aluminum, and it’s matched to a fully adjustable 46mm KYB piggyback shock absorber for excellent handling. Rear wheel travel is 11.02 inches for comfort even on tough terrain.
For excellent stopping ability, YFZ450R features dual front hydraulic disc brakes and a trick looking, lightweight wave-type rear rotor.
