The Yamaha MT-09 (FZ-09 in the US) is a Yamaha sport bike motorcycle with an 847 cc (51.7 cu in) inline triple engine. It has an all-new desaxé engine, a lightweight cast alloy frame, and USD forks.
Design and development
The MT-09 is an affordable, lightweight, torquey bike that will compete against the likes of the Triumph Street Triple , the Kawasaki Z800, the MV Agusta Brutale and Yamaha’s own FZ8. A very significant new model, the MT-09 is intended to restore Yamaha's fortunes, as the factory has in recent years lost its reputation for innovation. The MT-09's product manager, Shun Miyazawa, said Yamaha had considered in-line twins, triples and fours, and V-twins; but that the in-line triple gave the "best solution" of power, torque and low weight. Comparing the MT-09 to the Triumph Street Triple, he said the Triumph was a streetfighter, but the Yamaha was a "roadster motard".
Both the frame and the double-sided swinging arm are lightweight alloy units which are cast in two pieces. The frame castings are bolted together at the headstock and at the rear, but the swinging arm parts are welded together.
The MT-09 is the first Yamaha triple since the XS750 and XS850, both shaft-drive motorcycles produced from 1976 to 1981.
The newly developed three-cylinder engine has a crank pin offset on the crankshaft by 120 degrees. The regular firing order (0 degrees , 240 degrees , 480 degrees) to ensure a uniform , linear unfolding of power and torque. The specially modified exhaust manifold and different lengths of time allocations to the intake support this output yet . At the same time , the engine noise is optimized by headers including 3-in-1 exhaust system.
By means of an adjustable control of the engine electronics , the driver between the modes STD (road), A (sports) and B (rain) change and thus provide an altered response of the engine .
By using a lying under the seat central spring strut , an upside-down fork , the installed under the engine rear muffler and lightweight aluminum wheels , a mass centralization is brought about . This was originally developed by Buell concept leads to an improved handling.
The spring elements are adjustable in rebound, the rear strut additionally in the bias voltage. The choice of travel mode has no effect on the suspension setting (no electronically adjustable suspension).
The front-wheel- oriented seating position is upright and easily . The multifunction display is performed digitally as a liquid crystal display and next to Speed display and speed display also includes a clock and gear indicator. The fuel tank holds 14 liters, the manufacturer recommends the use of premium gasoline .
For the above special model MT-09 Street Rally include exclusive, new panel mounting parts and chassis components with which the torquey three-cylinder motorcycle provides its capabilities.
The new air scoops on the tank side starting number plates and fork covers give the MT model an even sportier style. And with the higher seat can playfully taking Supermotard attitude. In addition to the sensational Liquid Metal finish and new graphics the headlight surround and hand guards complete this model variant.
Shun Miyazawa said buyers are moving away from supersport bikes, adding, "(Yamaha) aim to create an older and younger brother and cousins (to the MT-09) - maybe the same capacity, but a slightly different concept". This is expected to mean updated TDM and TRX models using the MT-09's 850 triple engine, rather than a 270° parallel-twin engine.
