Features & Benefits
Engine
- Powerful Engine
- The YFZ450R is the most technologically advanced sport ATV on the market today. It combines a high-tech, quick-revving, titanium-valved, 449cc fuel-injected engine with a lightweight, professional-caliber cast aluminum/steel chassis. The power and chassis combination makes for a championship-winning machine time and time again.
- Advanced Cylinder Head
- The 449cc engine uses a five-valve cylinder head and titanium valve technology to deliver abundant power in the mid-range to top end with more “hit” feeling right off idle. The high compression ratio further improves overall engine performance.
- Fuel Injection
- The YFZ450R incorporates Yamaha Fuel Injection (YFI) for precise fuel delivery. With a 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.
- Assist and Slipper Clutch
- An assist-and-slipper clutch reduces clutch lever effort for less fatigue while at the same time increasing clutch plate pressure for positive engagement. This clutch system also reduces engine braking effect for faster cornering, particularly when downshifting.
- Compact Counterbalanced Engine
- The crankcase holds a crankshaft that’s ready to handle the increased demands of the racer as well as the counterbalancer to reduce vibration. The crankcase also houses the oil tank which helps to centralize mass for unmatched handling while making maintenance easier.
- Tuned Camshafts
- Camshafts have been revised to maximize the engine’s impressive power output from off the line all the way up to the top end.
Chassis/Suspension
- Race-Ready Ergonomics
- The body configuration allows more room for the racer to move around during the moto. To reduce fatigue, the seat is narrow in the front yet wide and padded in the rear.
- Durable, Rigid Wheels
- The wheels have been designed with the inner lip rolled in to increase rigidity, allowing for a reduction in weight while maintaining strength.
- Wide Track and Maxxis® Tires
- Wheels are set motocross-spec wide, near the allowable maximum of 50 inches, for great cornering speed. Maxxis® tires provide excellent handling and control. At 20 inches in the rear and 21 inches in the front, they provide better ground clearance than the competition.
- Adjustable Handlebar
- With a large diameter, the tapered handlebar reduces vibration and is mounted on 4-way clamps for exceptional adjustability. The two sets of holes in the handlebar crown and the eccentric clamps allow the rider to choose the standard setting: 10mm forward, 20mm forward or 10mm backward.
- Wide Foot Pegs
- The generous 2.6 inch-wide foot pegs are something riders will appreciate every time they want to get up on the pegs.
- Advanced Frame
- The lightweight frame is a combination of aluminum and steel. The frame member under the engine is steel and is used for its strength and low profile so that the engine can sit lower overall for excellent mass centralization and unmatched handling. The aluminum frame is bolted together, rather than welded, for maximum durability.
- Long A-Arm Suspension
- The front frame is as narrow as possible at the A-arm mounting points. This increases the A-arm length and reduces changes in camber as the suspension travels through its full range of motion.
- High-Performance Shocks
- The front KYB® shocks are longer for increased stroke, superb bump absorption and excellent anti-bottoming characteristics. The Kashima™ coating offers smooth operation while the 9.8 inches of wheel travel means the racer is ready for the most challenging tracks.
- Swingarm Rear Suspension
- The rear swingarm is crafted of strong, gravity-fed aluminum and is matched to a fully adjustable 46mm KYB® piggyback shock for excellent handling. For comfort even on tough terrain, the rear wheel offers 11.0 inches of travel.
Additional Features
- Light Throttle Action
- The throttle lever requires low effort for less fatigue during long motos.
- Compact LED Indicators
- The discreet panel on the fender in front of the rider gives vital indicators about low fuel, coolant temperature, check engine and neutral gear via an LED display.

The period of warranty shall be six months commencing on DELIVERY on any model which has been identified as being used for commercial applications, except for YF70R and YF45Z models (see Section D - 2. a).
The MANUFACTURER reserves the right to change the design of any model without obligation to modify any model previously manufactured.
Section B - Subsequent Owner
The warranty set forth in Section A may be transferred to any subsequent owner provided that the period of warranty has not expired and that the CUSTOMER has complied with all terms and conditions of this warranty. The subsequent owner has the responsibility for ensuring that a change of registration is sent to YAMAHA at the time of such transfer of ownership.
This transfer MUST be done by contacting the DEALER who will forward the following information to YAMAHA:

- the complete name and address of the subsequent owner;
- the indication that the subsequent owner has received and read the Owner's Manual and this warranty policy.
To obtain repairs under warranty, the CUSTOMER must:
- Ensure that the ATV is properly operated, maintained and stored as specified in the Owner's Manual;
- Give notice to a DEALER of any and all apparent defects immediately upon discovery, and make the entire ATV available at that time for inspection and repair at the DEALER'S place of business;
- Provide proof of warranty coverage to such DEALER (CUSTOMER'S copy of the New Vehicle Information Statement: N.V.I.S.);
- Authorize the DEALER to tear down the ATV for diagnostic evaluation should it be required. All warranty repairs must be done by a DEALER and final approval of any repairs rests with YAMAHA. All parts replaced become the property of YAMAHA.
- This warranty does not apply unless:
- The ATV has been fully assembled and set to the MANUFACTURER'S operating specifications by a DEALER prior to DELIVERY to the CUSTOMER;
- The CUSTOMER has followed the break-in, maintenance and storage instructions contained in the Owner's Manual and all other instructions shown in the Owner's Manual;

- appearance related damages of body parts. Examples of such damages include but are not limited to: scratches, dents, fading, flaking, peeling.

Section E - Emissions Control System Warranty
(For applicable models only)
YAMAHA warrants to the CUSTOMER of an ATV covered by this warranty that the ATV is designed, built and equipped so as to conform at the time of DELIVERY with all federal emissions standards applicable at the time of manufacture and that it is free from defects in materials and workmanship which would cause it not to meet these standards within a thirty-month period. Failures other than those resulting from defects in material or workmanship, which arise solely as a result of owner abuse and/or lack of proper maintenance, are not covered by this warranty.
Section F
This warranty is in addition to, and not a modification of, any warranty required by the laws of any province of Canada.
Subject to any applicable sales or consumer legislation, the above warranty is in lieu of any warranty or representation, expressed or implied, including any warranty of performance, merchantability or fitness for a particular purpose on the part of YAMAHA, and any other obligation or liability on behalf of YAMAHA, and the above warranty constitutes your sole remedy and the full liability of YAMAHA. In no event shall YAMAHA be liable for special, incidental or consequential damages howsoever caused, whether by negligence or otherwise resulting directly or indirectly from the use of the ATV, or the ATV having replacement parts or the unavailability of replacement parts.
YAMAHA does not assume, or authorize any person to create or assume for YAMAHA, any obligation or liability in connection with the ATV or any part thereof distributed by YAMAHA.
Original Equipment Tires
Tires supplied as original equipment on your ATV are warranted separately by the individual tire manufacturer or its representatives. Generally speaking, this warranty covers defects in workmanship or material.
Storing Your ATV
If your ATV is not to be used for 60 days or more, it must be properly stored to ensure against deterioration. You should consult your Owner's Manual for storage details, but WE RECOMMEND THAT YOU HAVE AN AUTHORIZED YAMAHA ATV DEALER PREPARE YOUR ATV FOR STORAGE. Their highly-trained staff have the experience and the qualifications to do the job right.
YAMAHA cannot accept responsibility for damage to your vehicle or personal injury resulting from negligence or lack of experience in the preparation of your ATV for storage.
