Invented by Arnold Wagner, founder of Ecomobile, the MonoTracer is essentially an 'enclosed motorcycle' . It has "landing gear" that is brought down to stabilize the vehicle when it stops or is at slow speeds. Once going, the operator retracts the gear, and the MonoTracer can lean up to 52 degrees in a turn. There are two MonoTracer models, both based on a very strong DuPont Kevlar® composite monocoque, or "fuselage".
The MT i1200 is powered by a fuel-injected BMW 1200cc gas engine. It goes from 0 to 60 in just over 5 seconds, and has an electronically limited top speed of 155 MPH. It gets over 50 mpg at highway speeds.
The MT i1200 had a base price of $80,000.
The MT e150 had a base price of $100,000 back in 2012.
Thus, new owners need to understand that they are learning to drive a completely different kind of vehicle, akin to learning to fly a plane -- which explains why many MonoTracer owners are private or professional pilots, or those who always aspired to be a pilot, but never had the time.
