Yamaha Gen-Ryu 2005 Prototype
Category: Prototype


Length/Width/Height: 2,610/1,090/1,050mm
Displacement: 599cc
Engine type: Liquid-cooled 4-stroke DOHC 4-valve in-line-4/motor

This model is a proposal for a “High-performance Hybrid Motorcycle.” Based on Yamaha’s “Genesis” design ideal and the new “G.E.N.I.C.H.” ideal reflecting the latest electronic control technologies, this model combines the lightweight, compact YZF-R6 600cc engine and a high output, high efficiency electric motor. It is designed to offer both the joy of handling of a motorcycle and the comfort and carrying capacity of a scooter. Features like the lightweight aluminum CF die-cast body with optimized rigidity balance, large diameter wheels and long wheelbase give this model running performance and handling similar to a 1,000cc class machine.

Furthermore, this model adopts a Yamaha H.M.I. (Human Machine Interface) system. This is a communications system that links ASV (Advanced Safety Vehicle) functions and smart functions to supply the rider with a variety of visual and audio information about the riding environment in the form of a system control program that lets the rider concentrate more completely on the act of riding. The ASV functions include (1) a vehicle-vehicle distance warning system using the latest communications technologies and (2) a cornering light system that improves nighttime vision when turning at intersections and curves. The smart functions developed jointly with Yamaha Corp. include (1) a noise canceling system that greatly reduces wind noise, (2) a short-wave tandem intercom system, (3) voice navigation function, (4) music player and hand-free cell phone function and (5) rear view monitoring system using a CCD camera and LCD display.

Length/Width/Height: 1,830-1,905/700/965-1,150mm
Power unit: Brushless DC motor

Taking full advantage of the greater chassis design freedom afforded by an in-wheel motor, this is Yamaha’s proposal of a completely new type of two-wheel-drive (2WD) EV (electric vehicle) with “Stretch” functions in the vertical and horizontal directions for the aluminum frame body that brings a very Yamaha joy of riding. In addition to the great drivability of the 2WD, it is possible to adjust not only the riding position but also the silhouette of the chassis to fit the rider’s body size, riding environment, road surface conditions and personal preference, as well as output characteristics. This is Yamaha’s proposal of a bike of the future that offers the kind of personal fit only possible with an electric vehicle.


Yamaha HV-01 2005 Prototype
Category: Prototype


Length/Width/Height: 2,050/800/1,300mm
Power unit: Gasoline engine/Brushless DC motor
Transmission type: Stepless,V-belt

This is a parallel hybrid scooter mounting an electric motor and gasoline engine. Despite the large body that gives a feeling of spacious comfort to the ride, this model has torque-y power development in the low rpm range that delivers the acceleration feeling of a bike one class above, as well as good fuel economy, environmental friendliness and performance that brings a real joy of riding. The frame is a CF aluminum die-cast type. At the same time it has convenient functions that only a hybrid bike can offer, such as a “quiet mode” (running only on the electric motor) and a “push mode” that makes pushing the bike in places like parking lots easy (super low-power drive when off the bike).

Yamaha FC-me 2005 Prototype
Category: Prototype


Length/Width/Height: 1,500/605mm/970mm
Machine weight: 69kg
Power unit: Permanent magnet synchonous motor (Fuel cell)
Maximum power: 0.95kW / 1,830r/min
Maximum torque: 5.4N•m / 560r/min

Fuel cell systems using hydrogen gas as their fuel are the most common, but it is difficult to make a compact system of this type. The “Yamaha Direct Methanol Fuel Cell (DMFC) System” uses a liquid methanol-water solution as its fuel, which eliminates the need for a converter and a pressurized (fuel) tank and thus makes it possible to create a lightweight system for a small vehicle requiring power in the 1 kW range without compromising on power output characteristics.
Based on survey data gathered from licensed public-road use of our “FC06 PROTO,” a prototype mounting the Yamaha DMFC system, the advanced fuel cell motorcycle model “FC-me” has now been created with improved performance in areas like reliability and running distance. By optimizing the control parameters for the fuel cell system, Yamaha’s engineers have achieved an energy conversion rate for the FC-me that is 1.5 times that of the FC06 PROTO, while re-evaluation of the body components has made possible a light machine weight of just 69 kg.


Yamaha VOX 2005 Prototype
Category: Prototype


Engine type: Liquid-cooled 4-stroke SOHC 3-valve single
Displacement: 49cc

This model boasts the first fuel injection system ever on a Yamaha 50cc scooter. It fits into today’s street fashion with its box-like body, flat sides and abundant trunk space. With higher handle bars for more comfortable riding position and a good sense of size, its long wheel base and fat tires, this model has the look of spacious ease and a ride that is comfortable and enjoyable.
