In the Trio, three seats were arranged in an arrowhead arrangement in a width of only 53 inches. The floor was a honeycomb sandwich of glass fiber and Kevlar, while the seat frames were aluminum and glass fiber. The rear-mounted 250cc twin-cylinder two-stroke engine drove the rear wheels through a continuously-variable belt transmission. It was presented at the 1983 Geneva Motor Show.
