All-New 890cc liquid-cooled 3-cylinder DOHC fuel-injected engine
The 2021 MT-09 features a newly developed 890cc liquid-cooled 3-cylinder, DOHC, 4-valve-per-cylinder fuel-injected (YCC-T) engine with a downdraft intake. The bore × stroke of 78 mm x 62.1 mm and 11.5:1 compression ratio provide outstanding torque with strong power delivery characteristics. Almost all of the fundamental parts of the engine; from the pistons and connecting rods to the crankshaft, camshafts and crankcase, have all been redesigned with a weight reduction. The combination of improved combustion efficiency and lighter weight results in an impressive 11% improvement in fuel efficiency as well, from 5,4 km/l to 4,8 km/l.
New lightweight aluminium frame
The 2021 MT-09 features a newly developed lightweight aluminium frame which has been further refined to showcase the MT's signature “agility.” To ensure both straight-line stability and handling performance, the balance of longitudinal, lateral and torsional rigidity has also been improved. Most notably, the lateral rigidity has been increased by approximately 50% for even more straight-line stability. The all-new frame is manufactured using the latest in Yamaha’s controlled filling (CF) die-casting technology which contributes to the 2021 MT-09's reduced weight.
6-axis IMU
The 2021 MT-09 features a newly developed 6-axis Inertial Measurement Unit (IMU) that retains the base performance of proven IMU in the YZF-R1 but is 50% smaller and 40% lighter due to a thorough review of the sensor layout. The engine control unit (ECU) that receives and reflects the data from the IMU is equipped with three rider aids: a Traction Control System (TCS), Slide Control System (SCS) and a front-wheel LIFT control system (LIFT). All three systems work together to help the rider concentrate on riding to better extract the machine’s potential. Each of the systems can also be turned on or off and have their levels of intervention adjusted to preference. With this best-in-class electronic control technology, the 2021 MT-09 gives you ultimate control in varying weather and surface conditions.
8,89 cm full-colour TFT instrument display
The MT-09 features an 8,89 cm full-colour TFT display that features a bar-type tachometer that changes colours as rpm rises or falls, a clock and displays for remaining fuel, average mileage, water temperature, air temperature and a gearshift indicator (colour reversed for gear in use). Easily switch between displays and information with the handlebar switches.
Next-generation design
2021 represents the 3rd generation of the MT-09. With the 2021 MT-09, the designers sought to better express the major advances made with the machine’s performance by visually accentuating the pure power of the bike. The minimalist design concept delivers an exterior with everything but the essentials stripped away to highlight lightness and agility while stimulating the rider's senses.
