2021 New MT-09 Unveiled: Fully Remodeled With Larger Displacement, Lighter Weight, And Renewed Styling!

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

The MT-09 ABS inherits and evolves the "Torque & Agile" character of the MT-09 ABS, and is designed to bring "feeling" to the rider. The "Rodeo Master" concept was developed. The new engine and chassis were both upgraded with new weight reduction technologies, and the new model is approximately 4kg lighter than the previous model.

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

The cross-plane concept is a design concept that effectively draws out only the combustion torque produced in the combustion chamber, with little inertial torque.

What's new for the 2021 model year?

1)The torque-rich 890cm3 engine.
The new 890 cm3, liquid-cooled, 4-stroke, DOHC, 3-cylinder, 4-valve, downdraft intake, FI engine is installed. The combustion chamber is narrow and compact, and high torque is extracted through quick combustion.

The pistons, connecting rods, crankshaft, camshaft, crankcase and many other major parts have been newly designed and made lighter.

The fuel delivery system has also been completely redesigned, with the injectors now mounted on the throttle valve, rather than directly on the cylinder head. The fuel supply system has also been completely redesigned, with the injectors mounted on the throttle valve instead of directly on the cylinder head. The injection is now directed to the back of the valve head for superior combustion efficiency. With these improvements in combustion and weight reduction, fuel economy has been improved by 9%* over the previous model.

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

The latest CF aluminum die-cast technology has been used to achieve a minimum wall thickness of 1.7mm (compared to the previous model, which had a minimum wall thickness of 3.5mm).
The rear frame is also made of CF die-cast aluminum, which is 1.5 kg lighter than the previous steel model.

Moreover, the rear arm is a box structure with welded aluminum panels, reducing the total weight of the frame, rear frame and rear arm by approximately 2.3kg compared to the previous model, for a refined agile riding experience. The frame has been adjusted for balance between longitudinal, lateral and torsional rigidity to achieve both straight-line stability and maneuverability, and the lateral rigidity has been increased by approximately 50%, contributing to straight-line stability.

3) Lightweight aluminum wheels made with unique SPINFORGED WHEEL technology for the first time

Yamaha's proprietary SPINFORGED WHEEL technology is used for the first time in a lightweight wheel that achieves a "balance of strength and toughness comparable to forged wheels, even though they are cast wheels" through the development of Yamaha's own aluminum materials and the establishment of a production method. These wheels are approximately 700 grams lighter at the front and rear than the previous model, plus the rear moment of inertia has been reduced by 11%, contributing to agile maneuverability.

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

The quality of the exhaust sound and intake sound is an important element that contributes to the "ride quality". The original design and tuning of the exhaust and intake air produce a sense of torque and acceleration. The 1.5-stage expansion chamber silencers and symmetrical tailpipes give the rider a sense of torque at start-up, with the exhaust sound synchronized with the drive force of the rear, and an audible switchy sound that grows as soon as the throttle is opened. As the rpm rises, the main sound source to the rider is adjusted to switch from the exhaust sound to the intake sound.

Three intake ducts of different cross-sectional area and length are used to enhance the sound in the mid- to high-rev range by tuning the sound pressure and making the intake sound resonate in each frequency range, creating a pleasant acceleration feel.

5) New IMU controls to support riding

The new IMU (Inertial Measurement Unit) has been installed. While maintaining the basic performance of the IMU, which has been proven in the 2015 and later models of the YZF-R1, the sensor configuration has been revised to achieve a 50% reduction in size and a 40% reduction in weight.

The ECU, which receives information from the IMU and feeds it back to the vehicle, incorporates three control systems: TCS, which reflects bank depth; SCS, which supports turning; and LIF, which suppresses the tendency of the front wheels to lift. The individual controls work in conjunction with each other to assist the rider in operating the machine and efficiently exploit its potential. Each system has an adjustable intervention level and an on/off setting.

6) New body design to stimulate the senses

As the third-generation successor to the first generation (2014) and the second generation (2017), new styling is adopted to express the potential of this greatly evolved model. The styling of the air intakes and the front wings that direct the wind into them is based on the theme of air flow and sound waves. The headlamps, silencers and other parts have been condensed into the center of the engine to express a powerful sense of torque. The smooth top line is combined with a short overhang silhouette to give the bike the "freedom to maneuver as the rider pleases" image that has been inherited from the first generation, and the zero-cover structure has been designed to minimize the number of covers. The styling is attractive and expresses the nimble handling of the lightweight body.

The bi-function LED headlamps (integrated Hi-Lo) are compact and well-designed, and provide excellent illumination. The contrast between the borderline between the illuminated area and the outside of the illuminated area is gentle and soft, with a uniform light distribution. The position lamps also have LED light guides and are designed to give an impression of the new MT face.
