Build to compete in the Polini Cup E50 polini class. Not pretty but it was fast. Build off an modified Murray frame, cut up and thinner lighter tubing was used in place of the heavy stock stuff. Polini motor ported to the gills with 1977 4 pedal race reed setup and custom intake. Heavily modified internals gears cut to reduce weight. Swingarm reinforced and adjustable shocks fitted.
