The new MT-09 2021 Yamaha Naked Bike comes with a new 890cc, liquid-cooled 3-cylinder DOHC fuel-injection engine. The motorcycle has a 4-valve-per-cylinder with an excellent bore (78mm) and stroke (62.1mm) compression ratio of 11.5:1, offering outstanding torque with sturdy power delivery characteristics. All of the fundamental components of the engine, from the pistons and connecting rods to the crankshaft, camshafts and crankcase, have been redesigned with a weight reduction. The combination of enhanced combustion efficiency and lightweight results in an impressive 11% improvement in fuel efficiency from 44 MPG to 49 MPG.
Thanks to extensive weight-reduction technologies, the new MT-09 2021 Yamaha Naked Bike comes in just 417 pounds. It is about 8 pounds lighter than the former 2020 Yamaha MT-09 Model. The new MT-09 2021 Yamaha Naked Bike features a newly developed lightweight aluminum frame that has been refined to showcase the MT’s signature agility. To guarantee both straight-line stability and handling performance, the balance of longitudinal, lateral, and torsional rigidity has been improved. One will not ignore the lateral rigidity because it increases up to 50 percent for even more straight-line stability. The new frame is factory-made using the latest in Yamaha’s controlled filling (CF) die casting technology that contributes to the weight reduction of the 2021 Yamaha MT-09.
The new MT-09 2021 Yamaha Naked Bike comes with a newly developed 6-axis Inertial Measurement Unit (IMU) that retains the base performance of IMU in Yamaha YZ-01. Still, it is 50% smaller and approximately 40% lighter due to a thorough review of the sensor layout. The new engine control unit (ECU) that receives and reflects the data from the IMU is equipped with three rider aids i.e.
- Slide Control System (SCS)
- Traction Control System (TCS)
- Front-wheel Lift Control System (LIF)
All of this three system works together that helps the rider in the concentrate on riding to extract the bike’s potential better. Each design can be easily turned on or off and comes with their level of intervention adjusted to preference. With the best-in-class electronic control technology, the Yamaha MT-09 offers the ultimate control in varying weather and surface conditions.
An all-new MT-09 2021 Yamaha Naked Motorcycle comes with 3.5 inches of full-color TFT display featuring a bar-type tachometer that changes color as rpm rises of fall, a clock, and shows for remaining fuel, water temperature, average mileage, a gearshift indicator, and air temperature. It is the 3rd generation of MT-09, and the designers sought to better express the significant advances made with the bike’s performance by visually accentuating the ultimate power of the motorcycle. The minimalist design concept provides an exterior with everything but the essentials stripped away to highlight lightness, compactness, and agility while stimulating the rider’s senses.
Engine Features
The new MT-09 2021 Yamaha Naked Bike comes with a powerful 890cc, liquid-cooled, DOHC, 3-cylinder, Fuel-Injected engine. It features a bore of 78mm and stroke of 62.1 mm, while the compression ratio of 11.5:1 offers outstanding torque with strong power delivery characteristics. Almost all engine parts, from the pistons and connecting rods to the camshaft, crankcase, and crankshaft, have been redesigned with weight reduction. The combination of enhanced combustion efficiency and lighter weight results in an impressive 11% improvement in fuel efficiency i.e., from 44 MPG to 49 MPG.
The fuel delivery system is completely redesigned. Previously in the 2020 Yamaha MT-09, the fuel injectors were attached directly to the cylinder head, but the fuel injectors of 2021 MT-09 are now connected to the throttle valve side of the throttle bodies. The new injectors now spray at the back of the intake valve heads to encourage atomization of the fuel and reduced adhesion of fuel particles to the port walls, delivering greater combustion efficiency. The throttle valve is operated with the help of the Yamaha Clip Controlled Throttle (YCC-Y) electronic system that has been widely proven on YZF series models and earlier MT-09 models.
The lightweight forged pistons help in smooth and high-revving power. The new forged connecting rods are made with the help of the fracture-split method. The new big-end ring of the connecting rod is firmly fractured and then reassembled to ensure an unparalleled degree of manufacturing accuracy. It makes a pair of perfectly matched halves that manufacture a much more accurate mating surface when the rods are bolted and joint together again around the crankshaft. The CP3 engine attaches its three-cylinder bore forward towards the exhaust side. This new offset reduces the piston to cylinder wall friction, thus creating more power and improved fuel economy. In contrast, the direct-plated ceramic-composite cylinder bore offers excellent heat dissipation and reduced friction.
The new muffler on MT-09 2021 Yamaha Naked Bike contributes to a lower overall weight and mass centralization but produces a low-frequency exhaust note at low speeds. The exhaust tailpipes are left-right symmetrical that directs sound pressure to either side of the bike, thus making an exhaust note that gives a sense of torque to the ride. The recently designed stainless steel header pipes are given a different curvature and length for an excellent pulse effect. The new intake system is completely redesigned to suit the new engine and offer a linear response when the riders open and closes the throttle.
The new three intake ducts also contribute to the excellent engine sound at mid-range and high rpm. These ducts are designed with different cross-sections and lengths so that the intake sounds resonate harmoniously at varying wavelength ranges. While the sound pressure is tuned to create a pleasing sound in the mid-and high-rpm range. It results in an air cleaner box that achieves good intake efficiency and a pleasant sound that improves acceleration.
The new MT-09 2021 Yamaha Naked Bike comes with an Assist and Slipper (A&S) clutch with specifications selected to best match the new engine for lighter clutch lever pull and smoother chassis behavior during downshifts. The transmission ratios have been improved, with the gear ratios for 1st and 2nd gear slightly higher than the previous models. The transmission works in combination with the improved momentum of inertia of the crankshaft and the fuel injection setting to offer the right balance of powerful torque feeling and ease of use, from acceleration to stop.
Chassis / Suspension
The new MT-09 2021 Yamaha Naked Bike weighs just 417 pounds; thanks to weight-reducing technology, the 2021 model is about 8 pounds lighter than the 2020 MT-09 model. The new MT-09 2021 Yamaha Naked Bike contains a newly developed lightweight aluminum frame that has been further advanced to showcase the MT’s signature agility. To guarantee both straight-line stability and handling performance, the balance of longitudinal, lateral, and torsional rigidity has been improved.
The lateral rigidity is enhanced by 50% for even more straight-line stability. The new frame is factory-made using the latest in Yamaha’s controlled filling (CF) die casting technology that helps in reducing weight. The new aluminum die-cast subframe has been used instead of the steel subframe used in the 2020 Yamaha MT-09. Thus it helps in reducing overall weight without compromising agility.
The newly developed swingarm comes standard in MT-09 2021 Yamaha Naked Bike that uses welded box shape of aluminum plate to attain both high rigidity and 250g lighter than former models. The motorcycle’s pivot structure connects the frame from the outside, compared to the previous model that hosts the reversed arrangement. Thanks to the alternation in the chassis’ rigidity and thorough engineering of the shapes of parts and components around the new seat, the new design retains the slim feel while still delivering outstanding straight-line stability at high speeds with more excellent cornering stability.
The new MT-09 2021 Yamaha Naked Bike features lightweight wheels manufactured using Yamaha-exclusive spin forging technology; these wheels help get outstanding handling. Thanks to the notable decreases (11%) in the momentum of inertia of the rear, these wheels make an enormous contribution to the MT-09’s agile handling character. The new MT-09 2021 Yamaha Naked Bike features a state-of-art braking system that contains a radial Nissin master cylinder for the front brake. The piston in the master cylinder moves parallel to brake lever travel, contributing to a linear hydraulic pressure supply for more excellent controllability. Following the footsteps of Yamaha YZF-R1, the new MT-09 2021 Yamaha Naked Bike is the only second Yamaha model to use the same technology that can be controlled with just a fingertip.
The riding positioned was designed to accommodate the rider of varying physiques. The handlebars and footpegs are adjustable in two different positions that help the rider set a place that offers them a secure feeling the moment they get on the motorcycle. The new handlebar clamps can be rotated 10mm forward, and the footpeg mounts can be raised 14mm higher and 4mm rearward. The new MT-09 2021 Yamaha Naked Bike comes with a 41mm KYB inverted front fork optimized setting that matches the character of the new compact frame for a smoother and more controlled ride. These settings slightly decrease movement in the pitch direction and make it easier for the rider to feel suspension working while riding. The rear and front suspension are adjustable for preload and rebound damping, while the front fork is adjustable for compression.
Additional Features
The 2021 model represents the 3rd generation of the MT-09. That’s why the designer sought to better express the significant advances made with the bike’s performance by visually highlighting the pure power of the motorcycle. The minimalist design concept provides an exterior with everything, but the essentials are stripped away to show lightness and agility while stimulating the rider’s senses. A compact bifunctional LED headlight with excellent beam spread comes standard on MT-09 2021 Yamaha Naked Bike. The beam’s edges have soother contrast to be easy on the eyes while emitting the soft and even spread of illumination.
The motorcycle features a projector design with a built-in internal lens in addition to the thick outer lens. Since the Yamaha MT-09 uses multiple LEDs to produce light, it can project complex illumination distribution across a broad field. The position lights use LEDs and light guides to give an impressive front face design, while the turn signals and newly designed LED taillight are LEDs. The rear fender eliminator, fly screen, engine guards, comfort seat and more can all be added to the motorcycle to support and enhance overall appearance.
