The Affordable and Easy-To-Build Reverse Trike
60+mpg and 100mph in the Eco-Exo & Eco-Exo-R

MEV Eco-Exo & Eco-Exo-R

The Eco-Exo is a stylish exoskeletal tandem seat reverse trike that is as economical as it is fun to drive. Designed with a small frontal area for high efficiency and low center of gravity for excellent roadholding, this three-wheeler will put a smile on your face without gutting your wallet. If you are looking to reinvigorate your daily commute while saving on gas, taxes and insurance, look no further than the Eco-Exo.

This new reverse trike kit uses a Suzuki Burgman 400 donor scooter to provide the vast majority of parts needed in the build. With over 32hp on tap from the 385cc engine, a V-belt drive variable transmission and a fuel economy of over 60mpg, the Eco-Exo is exceptionally easy to drive. As simple as a scooter, just twist and go! With ample power on tap and a low weight, the Eco-Exo easily moves you through traffic while providing the thrill of the open air, exoskeletal experience.

Required Donor Components

From a 2003-2006 Suzuki Burgman 400


Builders of the Eco-Exo and Eco-Exo-R have the choice of purchasing new parts or using a donor to obtain the majority of parts not included in the kit. Since many parts of the donor are unneeded, we recommend buying a 2003-2006 Suzuki Burgman 400, remove the parts you need and sell the remaining parts on eBay, Craigslist, or Message Boards. Based on experience from customer builds, you can recover a significant portion of the cost of the donor scooter if you sell off your unused parts. The following components can be provided by the Suzuki Burgman 400 scooter.
