The Yamaha MT-01 is a MT series motorcycle made by Yamaha from 2005 to 2012, available in Australia, New Zealand,^[1] Europe, India, Japan and parts of North America.^[2] But Yamaha Motor Corp. USA declined to import it to the United States, citing a small market for this style of motorcycle.^[3] It has unconventional features with a cruiser-style 1,670 cc (102 cu in) air-cooled, overhead valve V-twin engine but sportbike or naked bike style frame and suspension. The engine is derived from the Yamaha Warrior XV1700 and modified to suit application in the MT-01, while the forks and brakes are derived from the 2004 to 2005 Yamaha R1.^[4]

Originally unveiled as a concept motorcycle at the 1999 Tokyo Motor Show, strong public interest in the machine led Yamaha to develop a production model, which was released in 2005.^[5]^[6] The Motorcycle Design Association (MDA) awarded the MT-01 the Open Category award at the 2004 annual Motorcycle Design Awards at INTERMOT.^[7] During its production, the MT-01 remained largely unchanged.

Yamaha offered three different tuning kits developed with Akrapovič (named Stage 1, 2, and 3) for the MT-01, which provide performance increases from standard at each stage.^[8]

Stage 1: Two Akrapovič mufflers, heat shields, and solo seat kit, street-legal.
Stage 2: Full Akrapovič exhaust system, heat shields, solo seat kit, and Stage 2 high performance ECU, track-use only.
Stage 3: As above, and a velocity stack kit, valve spring set, stronger diaphragm clutch spring, gasket kit, high compression piston kit, high performance camshaft, and high performance ECU, track-use only.

Mick Withers set the 'Sports Compact' group 5 Australian record for a twin-cylinder motorcycle on a Stage 3 Yamaha MT-01 at a time of 11.77 seconds for a standing quarter mile pass @ 113.57 mph (182.77 km/h) at Compak Attak, Western Sydney International Dragway on 18 May 2008.^[9]

For the 2009 model year, Yamaha released a SP (special production) version of the MT-01,^[10] upgraded with Öhlins suspension, Pirelli Diablo Rosso tires and specific color scheme of red and white paint with a black and red seat.^{[citation needed]}
