Yamaha YFZ450R 2018 Sports Quad Bike – Price and Specifications
Engine
The new Yamaha YFZ450R 2018 Sports Quad Bike features the fuel-injected 449cc engine providing the best power characteristics. Its power delivery is smooth and strong with lots of midrange to top-end power. The engine features the new five-valve cylinder head and titanium valve technology, which is specially designed to deliver massive power in mid-range to top end. The high compression ratio further enhances the overall performance of engine. The all-new Yamaha Fuel Injection is best used for precise fuel delivery. Thanks to the bore of 42mm Mikuni throttle and 12-hole injector, this system offers an exceptional atomization of the fuel for maximum power. This new system also contains ISC (Idle Speed Control) for easy and reliable start-up and warming. An all-new assist and slipper clutch reduces the clutch lever effort for less fatigue while it also increases the clutch plate pressure for positive engagement. This clutch system also reduces the engine braking effect for faster cornering during downshifting. The new crankcase holds the crankshaft to handle increased demands of the racer as well as the counterbalancer to reduce vibration. This crankcase also contains the oil tank for mass centralization for better handling and easy maintenance like in 2017 Yamaha YFZ450R. The new camshafts have been entirely revised to maximize the engine’s impressive power output from off the line all the way up to the top end.
Chassis/Suspension
The new Yamaha YFZ450R 2018 Sports Quad Bike features the latest ergonomics. Its body configuration allows the rider to have movement space during riding off-road. The seat is kept narrow in the front while wide and padded in the rear to reduce the fatigue. The wheels are redesigned with the inner lip rolled in. It will increase its rigidity and will reduce overall weight while maintaining strength. The wheels are set motocross-spec wide featuring the 50 inches allowing for greater cornering speed. The latest Maxxis tires help to provide an excellent handling and control. The rear wheel is about 20 inches and the front is about 21 inches offering the better ground clearance. The large diameter tapered handlebar reduces the vibration and is fitted on new 4-way clamps for exceptional adjustability. The new two sets of holes in its handlebar crown and the eccentric clamps allow the rider to choose the standard setting i.e. 10mm back and 10mm to 20mm forward. The footpegs are about 2.6 inches wide offering a great sense of comfort during the ride. The frame of Yamaha YFZ450R 2018 Sports Quad Bike is the perfect combination of aluminum and steel for lighter weight. The frame member under its engine is steel, which is used for its combination of strength and low profile. It will allow the engine to sit lower in the frame for perfect mass centralization. The aluminum frame is being bolted together to achieve the maximum durability. The front frame has the A-arm mounting points. It increases the A-arm length and reduces the changes in camber as the suspension travels through its full range of motion. The front KYB shocks are longer for an increased stroke with the superb bump absorption and an excellent anti-bottoming characteristics. These shocks have Kashima coating for smooth operation. The wheel travel of 9.8 inches allows the rider to enjoy the smooth ride on all surfaces. This Yamaha ATV has much greater features than 2018 Yamaha YFZ50. The all-new rear swingarm is being crafted for strong gravity-fed aluminum and it is being matched to the fully adjustable 46mm KYB piggyback shock for better handling. The rear wheel travel is about 11 inches for more comfort on tough terrain.
