MARIETTA, Ga. – October 27, 2020 – Yamaha Motor Corporation, USA, today introduced the 2021 MT-09 as the new model in the company’s Hyper Naked motorcycle segment. Featuring a torque-rich engine, decreased weight and radical new looks, the all-new MT-09 fully showcases Yamaha’s signature Master of Torque design.
The Dark Side of Japan
As the first decade of the 21st century was coming to an end, a group of visionary designers and engineers were working on what would become one of the iconic motorcycles in the history of Yamaha Motor Co., Ltd. It was to be the beginning of a whole new chapter in the history of Yamaha.
The idea was to create a new kind of machine whose primary function was to inspire, excite and impress. A radically different motorcycle that would herald a new beginning, defy convention and be the catalyst for change, not just within Yamaha but also in the world of motorcycling. A bike that was designed to be ridden just for the thrill of the ride and would instill a real feeling of belonging and a clear sense of identity to a new generation of like-minded individuals.
It became clear that the future of motorcycling was going to be all about the emotion, the thrill, the feeling, the excitement. The rest is history. Quick, agile and aggressively styled, the naked MT-09 instantly attracted a new breed of younger riders who loved its brutal good looks, big-torque engine and adrenaline-charged ride. With its strong emphasis on the thrill of the ride, together with a focus on premium quality, minimalist design and the use of pure technology that enhances the riding experience – The Dark Side of Japan philosophy has inspired every Yamaha Hyper Naked model since day one and continues to be the force that makes every MT much more than just a motorcycle.
Lighter, more powerful and more technologically advanced in every area, the dynamic MT-09 is the purest expression of the Hyper Naked core values. The new MT-09 delivers an even more dynamic performance as well as more agile handling. Equipped with advanced electronic controls and an all-new chassis, the 2021 MT-09 is the ultimate package that delivers outstanding value in the 900cc Hyper Naked class.
New CP3 engine
To achieve a more torquey and agile feel, the 2021 MT-09’s 890cc engine has been completely redesigned and reduced in weight. Virtually every major component is new, including the pistons, connecting rods, camshafts and crankcases. Despite its larger capacity and higher power output, the 2021 powerplant is lighter than former models.
The torquey CP3 engine delivers ‘real world’ performance, enabling the rider to fully utilize its road-focused power delivery at everyday riding speeds. The larger-capacity engine makes the 2021 MT-09 an even more exciting and rewarding motorcycle that delivers stronger performance in every type of riding condition, whether it’s fast or slow, wet or dry.
Strong torque and power with increased economy
One of the key design features of the new 890cc engine is the completely new fuel delivery system. For 2021, the fuel injectors are mounted to the throttle valve side – versus attached directly to the cylinder head – for a better fuel atomization that also reduces the fuel adhesion to the intake port walls. This new system produces outstanding combustion efficiency and contributes towards the new model’s 11% increase in fuel efficiency.
New APSG ride-by-wire throttle
The MT-09’s Yamaha Chip Controlled Throttle (YCC-T) now features a new Accelerator Position Sensor Grip (APSG). Similar to the unit featured on the YZF-R1 and R1M but equipped with model-specific friction and throttle opening settings, this lightweight ride-by-wire system replaces the previous model’s pulley set-up to give excellent feel and reliability.
New intake and exhaust systems
The all-new 890cc engine is equipped with a redesigned high-efficiency air intake system and a newly designed exhaust. These systems are designed to enhance the sense of acceleration and torque when the rider is accelerating from a stop or powering out of a low-speed corner.
As the engine speed increases, the intake sound becomes more dominant and heightens the feeling of acceleration felt by the rider. This is accomplished via a new intake system with an air cleaner box featuring an all-new three duct layout, with each duct having a different cross section and length, further enhancing the MT-09’s torque-rich riding sensation.
Optimized transmission and uprated A&S clutch
To match the 2021 model’s increased engine performance, the transmission has been optimized by slightly raising the ratios on the first and second gear. To handle the torque, Yamaha’s Assist and Slipper (A&S) clutch uses a new material for its friction plates, and the cam angle is changed to give a lighter pull at the lever for an even gentler feeling when downshifting.
Die-cast aluminum Deltabox chassis
The 2021 MT-09 features an all-new lightweight CF die-cast aluminum Deltabox chassis that has been developed in unison with the larger capacity 890cc big-torque engine. Featuring larger twin beams that run directly from the steering head assembly through to the swingarm pivot to give optimal strength, the newly designed aluminum frame, subframe and swingarm are lighter, making a significant contribution towards the increased agility of the 2021 MT-09.
For enhanced handling characteristics, the frame’s longitudinal, lateral and torsional rigidity balance have been refined, with a 50% increase in lateral rigidity for high levels of straight-line stability. To match the more compact frame and shorter front forks, the head pipe position is lowered by 30mm, giving an increased feeling of front-end grip when cornering.
The new 250g lighter aluminum swingarm has a straighter right side for a more symmetrical appearance that complements the next-generation body design. To achieve better stability, the 2021 swingarm pivot is mounted between the frame structure to reduce unsprung weight and enhance the rigidity balance of the new frame.
Next-generation MT design
With its bare, beautiful and functional look, the new MT-09 represents the next major step in the ongoing evolution of the MT DNA. The design strips away everything but the essentials and presents an exterior that reveals the mechanical beauty of the bike to visually express the sound, torque, freedom and agility.
Flexible riding position
The riding position was designed to accommodate riders of varying physiques via adjustable handlebar clamps and footpeg mounting points, allowing riders to set a position that gives them a feeling of fit the moment they get on the bike. The fuel tank and seat have been refined to give the rider a feeling of being one with the machine.
6-axis Inertial Measurement Unit (IMU)
The new MT-09 is the first Yamaha Hyper Naked model to be equipped with a high-tech 6-axis IMU. Developed from the system that has been used on the YZF-R1 since 2015, the MT-09’s 6-axis IMU is 50% smaller and 40% lighter.
Constantly measuring acceleration in the forward-backward, up-down and left-right directions – as well as the angular velocity in the machine’s pitch, roll and yaw directions – the 6-axis IMU sends data in real-time to the ECU which controls the electronic rider aids. The class-leading array of rider aids includes lean-sensitive Traction Control System (TCS), Slide Control System (SCS) as well as a front wheel LIFt Control System (LIF) and Brake Control system (BC).
Lean-sensitive rider aids
By monitoring the speed difference between the front and rear wheels, the lean-sensitive TCS optimizes the drive force of the rear tire during acceleration. The SCS adjusts power when a rear wheel slide is predicted, allowing the rider to focus on their riding. Similarly, the LIF enables the rider to concentrate on the road ahead by adjusting engine output to control front wheel lift and smooth out machine behavior when pulling away and accelerating. The BC system works with the ABS and independently controls and modulates the front and rear brake pressure, helping to prevent wheel lock-up during hard braking when riding upright as well as when banking.
Three TCS modes
The TCS has three switchable modes, and each mode integrates three of the rider support systems so that the intervention levels are changed all at once in Modes 1 and 2. Mode 1 delivers moderate intervention while Mode 2 gives strong intervention and Mode M enables the rider to select manual settings. These electronic aids reduce the workload of the rider for more concentration on the road ahead.
3.5-inch full color TFT display
The new 3.5-inch full-color TFT display shows clear and precise data. Its lightweight construction and mid-sized layout blends seamlessly with the new LED headlight assembly and maintains the compact and agile feeling from the rider’s viewpoint. The bar-type tachometer changes color as rpm rise and fall, and the display includes a clock, gearshift indicator, water and air temperature and more. The new display is linked with the 6-axis IMU, and riders can switch between displays and also select their preferred mode for the electronic aids via a handlebar-mounted switch.
LED projector lighting
Compact, powerful and modern, the MT-09’s new full LED headlight assembly features a single central bifunctional projector headlight with multiple LEDs that provide a broad, even and powerful beam with soft edges for both low and high beam settings. Twin LED position lights present a bold new face for the MT-09, and they project a signature Y-shape icon to give the bike a predatory stare that represents the future direction of MT design. The theme is continued at the rear where the lightweight LED taillight projects a Y-shape illumination that confirms the bike’s next-generation MT DNA.
Quick Shift System
For the ultimate acceleration, the MT-09 gets a Quick Shift System (QSS) that ensures seamless and clutchless full-throttle upshifts and smooth downshifts. Together with the A&S clutch, this electronic aid transforms the riding experience and enables the rider to optimize the torque levels for more thrilling acceleration as well as higher levels of chassis stability and control when downshifting.
10-spoke Spin Forged wheels
The new, Yamaha-exclusive Spin Forged front and rear wheels are lighter with a significant 11% decrease at the rear wheel, making a big contribution to the bike’s agile handling character.
Fully adjustable KYB® front suspension
Featuring 41mm tubes that give smooth suspension action and maintain high levels of flex resistance, the new lightweight high specification KYB front forks are fully adjustable for preload, compression and rebound damping to match the character of the compact new higher rigidity frame while reducing the tendency to pitch. The new adjustable KYB rear shock is set up to suit the all-new chassis.
Front brake with radial master cylinder
To match the higher engine performance and more dynamic chassis character, the high-tech MT-09 is only the second Yamaha model to be equipped with the YZF-R1-type front braking system. Featuring a Nissin radial master cylinder in which the piston moves in a direction that’s parallel to the brake lever travel, this Supersport-class technology gives a more linear supply of hydraulic pressure to the dual front disc brakes for excellent controllability.
