2020 Yamaha YFZ450R SE Sports Quad Bike – Features and Price
Key Features
The 2020 Yamaha YFZ450R SE Sports Quad Bike is the most advanced and technological sport ATV in today’s market. It comes with the 449-cc engine with high-tech fuel injection, fast rotation, titanium valve, and a lightweight aluminum / cast steel chassis of professional caliber. This quad bike is the best combination of power and frame that makes the machine the champion all the time.
The YFZ450R SE is ready for motocross. The weldless structure is designed in lightweight aluminum, with a tensioned steel lower frame that allows the engine to sit lower for excellent mass centering. Suspension components and configurations reduce weight while providing light and precise handling and rider comfort. The aggressive style gives the YFZ450R SE a bold custom look, with extras like a GYTR front grab bar to match its unique graphic package.
The body was designed to offer excellent ergonomics and comfort to the driver, with more space to hang in the corners. The shape of the seat is padded in the right places to improve lap times. Body panels quickly come out without tools for maintenance. There is no need to remove its battery or other components to remove the fenders.
The 449-cc engine uses titanium five-valve cylinder head technology designed to provide abundant power in the middle to upper range, with a more “hit” feel right after idling. An auxiliary and sliding clutch reduces the effort of the clutch lever for less fatigue and, at the same time, increases the pressure of the clutch plate for positive engagement. This clutch system also reduces the engine’s braking effect, which allows for faster turns, especially when reducing gear.
The 2020 Yamaha YFZ450R SE Sports Quad Bike incorporates Yamaha fuel injection for accurate fuel delivery. With a massive 42 mm Mikuni throttle body and 12-port injector, this system provides exceptional fuel atomization for maximum power. The new system also includes ISC (Idle Speed Control) for secure and reliable startup and heating.
Engine
The 449cc engine with fuel injection has excellent power characteristics. The power supply is smooth and stable off the line, with a lot of medium to top power. The 449-cc engine uses a five-valve cylinder head and titanium valve technology engineered to give abundant energy in the middle range to the upper end, with more “blow” feeling right after idling. The high compression ratio further improves the engine’s overall performance.

With a massive 42 mm Mikuni throttle body and 12-port injector, this system provides exceptional fuel atomization for maximum power. The system also contains ISC (Idle Speed Control) for secure and reliable startup and heating. The camshafts have been revised to help maximize the engine’s impressive power output, from off-line to the upper end.
An auxiliary and slip clutch decreases the effort of the clutch lever for less fatigue and at the same time, enhances the clutch plate pressure for positive engagement. This new clutch system also reduces the engine’s braking effect, which allows for faster turns, especially when reducing gear. The crankcase has a crankshaft that is ready to handle the growing demands of the aisle, as well as a counterbalance to reduce vibration.
Chassis / Suspension
The body configuration allows more space for the driver to move during the race. The seat is thin at the front, but broad and padded at the rear to reduce fatigue. The wheels are designed with the inner edge rolled up. It increases stiffness, allowing for a reduction in weight while maintaining strength. The frame is the best combination of durable aluminum and steel for lightweight. It will enable the engine to be generally lower for excellent mass centering and unmatched handling.
The wheels have a motocross specification width, close to the maximum allowable of 50 inches, for high cornering speed. All-new Maxxis tires help provide excellent handling and control. With 20 inches at the rear and 21 inches at the front, they provide better ground clearance than the competition. The piles are a generous 6 cm wide, something that riders will appreciate whenever they want to climb the piles.
The large-diameter tapered handlebar reduces vibration and is mounted on 4-way clamps for an exceptional fit. There are two sets of holes in the handlebar crown and eccentric calipers allow the rider to choose the standard configuration, 10 mm or 20 mm in front or 10 mm in the rear. The front section of the frame is as narrow as possible at the mounting points of the arm A. This increases the length of the arm A and reduces changes in curvature as the suspension travels over its full range of motion.
KYB front shock absorbers are longer for more extended travel with excellent impact absorption and unique anti-back characteristics and have Kashima coating for smooth operation. 9.8 inches of wheel displacement means that this driver is up to even the most challenging tracks. The rear swingarm is made of sturdy gravity-fed aluminum and is compatible with a fully adjustable 46 mm KYB shock absorber for excellent handling. The rear-wheel travel is 11.0 inches for greater comfort, even in steep terrain.
Additional Features
The aggressive style gives the 2020 Yamaha YFZ450R SE Sports Quad Bike a bold custom look, with extras like the new GYTR front grab bar to match its unique graphic package. The throttle lever requires little effort for less fatigue during long trips. The discreet panel on the fender in front of the pilot provides vital indicators on low fuel, coolant temperature, engine check, and neutral via an LED display.
