2026 Yamaha MT-09UNLEASH YOUR DARKNESSThe industry benchmark in Hyper Naked performance with razor sharp handling, thrilling 890cc triple-cylinder power, class-leading technology and distinctive Dark Side styling.Features may include:Powerful 890cc Three-Cylinder EngineYamaha's renowned 890cc liquid-cooled CP3 engine is light, powerful and provides a thrilling wave of torque from low RPMs. A combination of carefully tuned induction sound and distinctive crossplane triple exhaust note provides a resonance which only heightens the feeling of acceleration. Throttle valves are governed by the Yamaha Chip Controlled Throttle (YCC-T) system enabling finer actuation and precise control.Advanced Six-Axis IMUThe MT-09 features an advanced six-axis Inertial Measurement Unit (IMU) that matches the base performance of proven IMU in the YZF-R1 Superbike. Data collected from the IMU and wheel speed sensors enable a high-tech suite of rider aids including a four-mode Traction Control System (TCS), Slide Control System (SCS), front wheel Lift Control System (LIF) and a two-mode Brake Control System. Each of these systems can be turned off and Traction Control, Slide Control and Lift Control can have their levels of intervention adjusted to preference.Lightweight CF Die-Cast Aluminum FrameThe MT-09 features an advanced, lightweight aluminum frame 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 are all carefully considered and finely tuned. The frame is manufactured using Yamaha's groundbreaking controlled fill (CF) die casting technology which contributes to its light weight.Five-Inch TFT Display with Smartphone ConnectivityRiders can link their smartphone to the rich, full-color TFT display via Yamaha's free Y-Connect app to receive message notifications, calls and listen to music (through use of an aftermarket Bluetooth(R) headset, not provided). Additionally, full turn-by-turn navigation is available through the Garmin(R) StreetCross app to make each journey easier.Aggressive Next-Generation StylingAggressive next-generation styling takes the Hyper Naked look to a new level with sharper, more defined lines and minimal bodywork. A bi-functional LED headlamp is shrouded in a cover, creating a compact and unified relationship with the fuel tank and tail section, while a more forward-leaning stance maintains the edgy street aesthetic synonymous with the MT name.Powerful 890cc Three-Cylinder EngineYamaha's renowned 890cc liquid-cooled CP3 engine is light, powerful and provides a thrilling wave of torque from low RPMs. A combination of carefully tuned induction sound and distinctive crossplane triple exhaust note provides a resonance which only heightens the feeling of acceleration. Throttle valves are governed by the Yamaha Chip Controlled Throttle (YCC-T) system enabling finer actuation and precise control. The 2026 Yamaha MT-09 SP stands out with its high-revving, liquid-cooled, DOHC inline three-cylinder engine, delivering a compact 890 cc heart that combines spirited performance with precise throttle response. Its four valves per cylinder and 11.5:1 compression ratio fuel the midrange with confident punch, while a six-speed transmission with a multiplate wet clutch and Assist helps refine clutch control in urban streets and winding roads alike. The bike's weight is listed at wet 425 pounds, a balance that supports nimble handling without sacrificing stability on fast straights or tight switchbacks. Capability and chassis define the MT-09 SP as a distinct riding instrument. A front suspension travel of 5.1 inches paired with a rear single shock featuring adjustable preload and rebound damping delivers a responsive ride, while the 134.51-foot front suspension specification hints at a composed, controlled feel over varied surfaces. Braking is confident with a separate front and rear setup, and Bridgestone Battlax Hypersport S23 tires in 120/70ZR17 front and 180/55ZR17 rear contribute to precise cornering sense. The geometry is sharpened by a 24.7-degree rake and a wheelbase of 4.69 feet, supporting quick-direction capability without sacrificing stability at speed. Form and finish meet rugged practicality in the MT-09 SP. The 3.7-gallon fuel tank keeps you in the saddle longer between fueling stops, while the compact body measures 82.3 inches in length, 32.3 inches wide, and 3.76 feet tall, presenting a tall, aggressive silhouette without overwhelming cockpit access. Standout features extend to a 2.71-foot seat height that invites an assertive riding posture, and a chain final drive that keeps maintenance straightforward.
