eBay: 125MPG Reverse Trike

Built by "John", a Ford Efficiency Engineer, he calls it the HyperRocket :

This 2 passenger 3 wheel vehicle was professionally engineered for maximum fuel economy and good performance. It is registered as a motorcycle with a clean title and has approximately 3200 miles on it.



The chassis is made from aircraft materials and components utilizing an indy car style rocker arm double wishbone suspension. The engine is a 250cc liquid cooled, four stroke, DOHC 2 cylinder with a six speed transmission. It weighs just 505 lbs with a .16 coefficient of drag.



For safety it has 4 point seat belts, roll bar and front mounted IMPAXX crash foam as now used in NASCAR sides. The front headlight is a very bright projector HID and the rest of the lights are LED. The front turn signals are integrated into the rear view mirrors for aerodynamics.



As pictured with the car tires and full canopy, it achieves 105 mpg cruising on the highway at 65mph. When equipped with the pictured motorcycle tires (not included) and a smaller rear sprocket it achieved 125 mpg @ 65mph.

Considering the work Craig Vetter is doing to develop a two-wheeled vehicle acheive 100 MPG @ 70 MPH into a 25 MPH headwind and still having a ways to go to achieve his goal, that's doing rather well. Drag coefficient appears to be the key to high MPG. The question is whether a motorcycle can ever achieve a low DC with an exposed front wheel.

Yeah, but imagine what some yuckster in a Hummer could do to you on the Interstate!:ohmy: :ohmy: :ohmy: :blink: :S
