The MT-01 is a motorcycle made by Yamaha since 2005, available in Australia, Europe, India, Japan and North America. It has unusual 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.

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.[2][3] The Motorcycle Design Association (MDA) awarded the MT-01 the Open Category award at the 2004 annual Motorcycle Design Awards at INTERMOT.[4] Since its release, the MT-01 has remained largely unchanged.

There are three tuning kits (Stage 1, 2, and 3) available for the MT-01, which realise performance increases from standard at each stage.
