Some concept bikes make it into production, some don’t. Here’s a run-down of some of the neat design studies unveiled during the past few years.
Confederate’s Renovatio (Rebirth) concept was designed with a liquid-cooled V-twin producing 150hp standard or 190hp supercharged.
Unveiled in October at INTERMOT, Honda’s V4 Concept is a design study made to celebrate the 30th anniversary of the OEM’s V4 four-stroke engine.
Victory Vision 800
The Victory Vision 800 concept featured an 800cc 4-stroke liquid-cooled parallel twin mated to an automatic constant variable (CVT) transmission.
Unveiled at the 2007 Tokyo Motor Show, the Yamaha Tesseract is capable of leaning into turns and gets its power from both a V-Twin engine of undisclosed size along with an electric motor.
Aprilia Mana X
An update to the Mana unveiled in 2006, the radical 839cc V-twin Aprilia Mana X, shown at EICMA 2008, is a 383-lb. bike producing 55hp at 8000rpm.
Powered by a hydrogen fuel cell, the Bombardier Embrio concept uses “outrigger wheels” until it hits 15mph, and then it becomes a gyroscopically balanced unicycle.
The Gulak Uno
The Uno was invented by 18-year-old Canadian Ben J. Poss Gulak and shown at the 2008 National Motorcycle Show in Toronto. Like the BRP Embrio, the electric-powered vehicle also uses a gyroscope for balance. Like a Segway, to make it go forward, you lean forward. To slow it down, you lean backward. It has two wheels mounted side-by-side.
Chrysler’s former president, Wolfgang Bernhard, drove the Tomahawk on stage at the Detroit international auto show in 2003. This radical concept is powered by a V-10 engine sourced from the Viper.
Derbi DH 2.0
Shown at EICMA last month, the Derbi DH 2.0 can be described as a motorized mountain bike. It has fuel in frame, an automatic transmission, and a 96cc single-cylinder four-stroke producing 8hp.
Suzuki’s Crosscage is a fuel-cell motorcycle featuring an air-cooled fuel system from and secondary lithium-ion battery. Look away from the traditional engine – the motor is inside the huge swinging arm/rear wheel assembly. The faux petrol tank covers the fuel cell, the hydrogen fuel tank is where the motor is normally and the battery and motor controller sit underneath.
The Husqvarna SMQ450, powered by a 450cc liquid-cooled single, was shown for the first time at EICMA in November.
First shown at the 2007 Tokyo Motor Show, the EVO-6 is powered by an 1800cc six-cylinder engine sourced from the Gold Wing.
Also unveiled at the 39th Tokyo Motor Show was Yamaha’s Gen-Ryu, equipped with a 600cc engine and electric motor hybrid system.
BMW Lo Rider
The BMW Lo Rider allows the customer to adapt the entire character of the vehicle to individual taste, and take full pleasure in assembling the unit into anything from a cool cruiser to an aggressive muscle bike. The design elements that customers can individually combine include a raised or lowered exhaust system; a seat for one or two, or an aluminum perch seat; a headlamp unit in classic shape or in streetfighter style; a fuel tank with or without aluminum trim; four paint finishes for the fuel tank; three paint finishes for the engine casing; and front and rear wheel fenders finished either in black or chrome.
Aprilia FV2 1200
The year 2007 marked the 20th anniversary of Aprilia’s first GP win. The concept FV2 1200 served as a tribute to that anniversary, and offered a glimpse of the technical and stylistic attributes Aprilia planned to develop for future production bikes. It’s powered by a 1200cc, 90° V-twin engine and boasts a ride-by-wire control system integrating traction control, a latest generation ABS system and electronic suspension management. The bike’s dashboard incorporates a multifunctional instrument cluster that can be interfaced with a PC, making it possible to download telemetric data for personal performance evaluations, reconfigure the information shown on the matrix display, load new mappings from the internet, display itineraries, and integrate GPRS and GSM modules for mobile phone connectivity.
Vectrix Electric Superbike
Unveiled at EICMA 2007, the Vectrix Electric Superbike is powered by a 240v, 7.5KWh battery that drives an electric motor in the rear hub. The 449-lb. bike has a claimed top speed of 125mph and a single-charge range of around 70 miles.
