2026 Yamaha MT-09 Review: Naked Bike Performance

Yamaha's MT-09 received its biggest update in 2021 since its launch. The latest generation brings major improvements to every part of the motorcycle. From a bigger engine to cutting-edge electronics, the 2021 model showcases a brand new chassis design, fresh styling, and better performance.

The 2021 MT-09's engine now packs 889cc, delivering more power than before. Riders can pick between two variants - the standard MT-09 and the premium MT-09 SP. The SP version comes with better suspension parts and exclusive design elements. This complete review looks at the bike's new engine specs, electronic features, handling, and real-life performance to help buyers understand what it can do.

REVAMPED ENGINE AND CHASSIS

Yamaha's engineering rise centers on their completely redesigned CP3 engine. This powerplant now boasts an expanded 889cc capacity that delivers 117.4 horsepower at 10,000 rpm and 68.6 lb-ft of torque at 7,000 rpm. The improved engine features new pistons, connecting rods, camshafts, and crankcases that engineers designed to reduce weight while ensuring reliable performance.

The engine demonstrates remarkable efficiency gains with an 11% boost in fuel economy that reaches 49 mpg. A redesigned fuel delivery system features repositioned injectors that spray directly at the intake valve heads to optimize fuel atomization and combustion efficiency.

New 889cc CP3 engine specs

The core team has outlined these essential engine specifications:

- Bore × stroke: 78 mm × 62.1 mm

- Compression ratio: 11.5:1

- DOHC 4-valve-per-cylinder configuration

- Yamaha Chip Controlled Throttle (YCC-T)

Lightweight aluminum frame

The 2021 MT-09's chassis marks a breakthrough in motorcycle engineering. Yamaha's controlled filling (CF) die-casting technology produces a new frame that delivers 50% greater lateral rigidity while maintainingoptimal longitudinal and torsional characteristics. The frame demonstrates Yamaha's engineering excellence with its remarkably thin 1.7mm profile at its narrowest point.

Yamaha replaced the steel construction with an aluminum subframe that weighs 3.3 pounds less. The redesigned swingarm weighs 250g less than the previous model, which improves the motorcycle's agility and handling precision.

Improved power-to-weight ratio

The 2021 MT-09 achieves an impressive weight reduction at just 417 pounds. The bike weighs 51 pounds less than the Z900 and 57 pounds less than the BMW F900R, giving it a clear edge over its competitors.

The MT-09 stands out in its class with more power output and less weight. Its enhanced power-to-weight ratio delivers exceptional performance and efficiency. Yamaha shows its engineering excellence by using lightweight materials in the chassis and engine components to optimize
