Yamaha Announces New MT-09 Full Model Change with Increased Displacement, Lighter Weight and New Styling

Yamaha Motor Co., Ltd. has announced the release of the fully remodeled "MT-09 ABS," a road sport model equipped with a liquid-cooled, 4-stroke, DOHC, 3-cylinder, 4-valve, 890cm3 engine developed based on the "Crossplane Concept "* for the European market. The MT-09 ABS is scheduled to be released in Japan in the spring of 2021 or later.

The MT-09 ABS was developed based on the concept of "The Rodeo Master," which inherits and evolves the "Torque & Agile" character of the previous model and brings "Feeling" to the rider. While the engine and body have been significantly improved by renewing both, weight reduction technologies have been incorporated throughout, resulting in a weight reduction of approximately 4 kg compared to the previous model.

The new features include 1) a new torqueful 890cm3 engine, 2) a new frame made of lightweight CF die-cast aluminum, 3) lightweight aluminum wheels with the unique SPINFORGED WHEEL technology used for the first time, 4) a sound design that expresses a sense of torque and acceleration, 5) various controls to support driving operations using the new IMU, and 6) a new body design that stimulates the senses.

The Crossplane Concept is a design concept that efficiently extracts only the combustion torque produced by the combustion chamber alone, with little inertial torque.

New features for the 2021 model year

1) Torqueful 890cm3 Engine

It is equipped with a newly developed 890cm3, liquid-cooled, 4-stroke, DOHC, 3-cylinder, 4-valve, downdraft intake, FI engine. It has a narrow, compact combustion chamber for quick combustion and high torque.

Many of the major parts such as the pistons, connecting rods, crankshaft, camshaft, and crankcase have been newly designed to reduce weight.

The fuel supply system has also been redesigned. The injectors have been relocated from the cylinder head to the throttle valve side. The injectors are now mounted on the throttle valve side, instead of directly on the cylinder head, and the injection is directed toward the back of the valve umbrella to achieve superior combustion efficiency. These improvements in combustion and weight reduction have resulted in a 9%* improvement in fuel economy over the previous model.

2) New frame made of lightweight CF aluminum die-cast

Using the latest CF aluminum die-casting technology, a lightweight aluminum frame with a minimum wall thickness of 1.7mm has been adopted (the minimum wall thickness was previously 3.5mm). The rear frame is also made of CF aluminum die-cast and weighs 1.5kg less than the previous model made of steel.

In addition, the rear arm has a box structure with welded aluminum panels, and the total weight of the frame, rear frame, and rear arm is approximately 2.3 kg lighter than before, refining the agile driving style. In order to achieve both straight-line stability and maneuverability, the balance of longitudinal, lateral, and torsional rigidity has been adjusted in this frame, and in particular, the lateral rigidity has been increased by approximately 50% compared to the previous model, contributing to straight-line stability.

3) Lightweight aluminum wheels with unique SPINFORGED WHEEL technology, which is being used for the first time

Yamaha's unique "SPINFORGED WHEEL" technology, which achieves a balance of strength and toughness comparable to that of a forged wheel despite being a cast wheel, is used for the first time in a lightweight wheel. It is approximately 700g lighter front and rear than the previous model, and furthermore, the rear moment of inertia has been reduced by 11%, contributing to agile athletic performance.

4) Sound design that expresses a sense of torque and acceleration

"Focusing on the fact that the quality of the exhaust and intake sounds is an important factor that contributes to the "ride quality", Yamaha have designed and tuned the exhaust and air intake in a unique way to create a sense of torque and acceleration. The 1.5-stage expansion chamber silencer and symmetrical tailpipes give the rider a sense of torque as the exhaust note synchronizes with the rear driving force when starting off, and a switchable sound as the note increases and is heard the moment the throttle is opened. As the rpm rises, the main sound source to the rider switches from the exhaust to the intake.

▲Silencer with 1.5-stage expansion and left-right tailpipe

▲The three intake ducts in the air cleaner box produce a pleasant sound

Three intake ducts with different cross-sectional areas and lengths are used for intake sound, and the intake sound from each duct is made to resonate in each frequency band, and the sound pressure is tuned to emphasize the sound in the mid to high rev range, producing a pleasant acceleration feeling.

5) Various controls to support driving operations using the new IMU

The newly developed "IMU" (Inertial Measurement Unit) has been installed. While maintaining the basic performance of the "IMU," which has been proven in the "YZF-R1" since the 2015 model year, it has achieved a 50% reduction in size and a 40% reduction in weight by reviewing the sensor configuration.

The ECU, which receives the information from the IMU and feeds it back to the vehicle, incorporates three control systems: TCS, which reflects the depth of banking; SCS, which supports turning; and LIF, which prevents the front wheels from lifting off the ground. The individual control systems work in conjunction with each other to support the driving operation and bring out the potential of the machine efficiently. The intervention level of each system can be adjusted and set to ON or OFF.

6) New body design that stimulates the senses

The new styling expresses its potential, which has evolved significantly as the third generation succeeds the first generation in 2014 and the second generation in 2017.

The styling of the air intakes and the front wing, which directs the wind into the air intakes, is based on a theme that evokes sound, such as the "flow" of air and the "waves" of sound. The headlamps, silencers, and other parts are condensed in the center of the engine to express a strong sense of torque. In addition, the smooth topline and short overhang silhouette combine to create an image that has been inherited from the first generation of the motorcycle, "an image that can be controlled at the rider's will. In addition, the zero-cover styling, which minimizes the use of covers, expresses the nimble handling of the lightweight body.

The bi-functional LED headlamps (Hi-Lo integrated) are compact, well-designed, and provide excellent illumination. The contrast between the illuminated area and the outside of the area is gentle, soft, and evenly distributed. The position lamps are also LED type with a light guide, which gives the impression of a new MT face.
