1st Generation - The TriVette
The TriVette is a first generation design, developed specifically as a response to the first Arab Oil Embargo in late 1973. They were designed and manufactured by Bob Keyes. There were only 27 total of these built between 1974 to 1978. 26 of them were factory made and 1 was kit built. This kit was later sent back to the factory to finish the assembly.

The factory was licensed by the State of California as a motorcycle manufacturer, and the TriVettes were manufactured in Ventura, California on a custom order basis from 1974 through 1978. The TriVettes met all applicable State and Federal motorcycle standards as of the time of manufacture. Most of the TriVettes used powertrains and other components from the Fiat 850's of the late 1960's/early 1970's. These were excellent powertrains that provided spirited performance and extremely good fuel economy in a 1,140 pound vehicle. They typically got 50 mpg in heavy city traffic and 65 mpg on the freeway. Also, because of their light weight and excellent balance, they are a lot of fun to drive.

3rd Generation - The Vigillante
Bob Keyes then started work on the third generation vehicle. More information is available at his site www.vigillante.com . This is basically a slightly modified version of the Police pursuit vehicle. One of the options is a 500 HP engine that will do 0-60 in 3 seconds flat!! It also has a top speed over 200 MPH!!! The HP to weight ratio is the same as an Indy car! Believe me when I tell you this vehicle roars.
