2021 Yamaha MT-09

2021 Yamaha MT-09 SP

Featuring exclusive, special edition coloring, premium KYB and Öhlins suspension and a cruise control system, experience the latest masterpiece to emerge from the Darkness.

• All-New 890cc Liquid-Cooled 3-Cylinder DOHC Fuel-Injected Engine

The MT-09 SP 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 × 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 reduction in weight. The combination of improved combustion efficiency and lighter weight results in an impressive fuel efficiency of 49 MPG.

• Efficient Fuel Delivery System

The fuel delivery system has been completely redesigned from the former MT-09. The fuel injectors were attached directly to the cylinder head, but the fuel injectors of the MT-09 SP are now attached to the throttle valve side of the throttle bodies. The injectors now spray at the back of the intake valve heads to promote atomization of the fuel and reduce adhesion of fuel particles to the port walls, producing outstanding combustion efficiency. The throttle valve is operated using the Yamaha Chip Controlled Throttle (YCC-T) electronic system which has been widely proven on YZF series models as well as the earlier MT-09 models.

• Lightweight Forged Pistons

The lightweight forged pistons allow for smooth, high-revving power.

• Fracture-Split Connecting Rods

The forged connecting rods are made using the fracture-split method—where the big-end ring of the connecting rod is purposefully fractured and then reassembled—to ensure an unparalleled degree of manufacturing accuracy. This creates a pair of perfectly matching halves that produce a much more precise mating surface when the rods are bolted together again around the crankshaft.

• Lightweight Aluminum Frame

The MT-09 SP's lightweight aluminum frame showcases the MT's signature “agility.” To ensure both straight-line stability and handling performance, the balance of longitudinal, lateral and torsional rigidity have 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 MT-09 SP's light weight

• Aluminum Die Cast Subframe

The MT-09 SP employs a controlled filling aluminum die-cast subframe that reduces weight, contributing to the model’s signature feeling of agility.

• Next-Generation Design

2021 represents the 3rd generation of the MT-09. And with the MT-09 SP, 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 simulating the rider's senses.
