The Yamaha Niken is a 845 cc
The development concept was called "New Type of Agility & Controllability". The model was shown as a concept vehicle at the 2015 Tokyo Motor Show, and launched at the 2017 show. It was announced for release in Japan on September 13, 2018, and order reception began on the same day.
Vehicle equipment:
Water-cooled in-line three-cylinder engine, mechanically identical to the sports naked 
The Niken arranges the front fork outboard of the front wheels, in order to allow a bank angle of 45 degrees allowing for higher corner speeds than the Tricity, which has the front fork inboard of the front wheels. The spacing of the front wheels is 410 mm. The newly developed steering mechanism achieves operability and steering very close to that of a normal motorcycle.

The application of the Road Traffic Act and the Road Act is equivalent to that of motorcycles, and the legal maximum speed is 60 km / h on general roads and 100 km / h on national highways. According to the Road Transport Vehicles Act, it is treated as a "motorcycle with sidecar" and is classified as a two-wheeled small car because of its displacement of 400cc or more. Therefore, it is subject to the automobile inspection registration system (vehicle inspection).

Overview
The Niken is a commercial version of the concept bike "MWT-9" announced by Yamaha in 2015. As part of Yamaha's LMW line of bikes - Leaning Multi Wheel - the Tricity with 125cc had previously appeared in 2014. The basic concept is that the two front wheels move in conjunction with each other when the vehicle body is tilted, while the body can be moved like a normal motorcycle. The name ''Niken'' is a coined word meaning "two swords", referring to the dynamic movement of the front two wheels like a sword master's two blades.The development concept was called "New Type of Agility & Controllability". The model was shown as a concept vehicle at the 2015 Tokyo Motor Show, and launched at the 2017 show. It was announced for release in Japan on September 13, 2018, and order reception began on the same day.

Legal status
;In EU ;In USA ;In Japan According to the Japanese Road Traffic Law, as with the Tricity, the Niken falls under the requirements for three-wheeled vehicles specified in the notification by the Prime Minister and is classified as a ''Specific Motorcycle'', more precisely a ''Specific Large Motorcycle''. This type requires a Large Motorcycle driving license.The application of the Road Traffic Act and the Road Act is equivalent to that of motorcycles, and the legal maximum speed is 60 km / h on general roads and 100 km / h on national highways. According to the Road Transport Vehicles Act, it is treated as a "motorcycle with sidecar" and is classified as a two-wheeled small car because of its displacement of 400cc or more.
