French designer Andre de Cortanze's Elf-X road racer is more than an experiment. Although currently in the research and development stage. it is hoped
that the bike will be ready to compete in selected F750 events later this year. GP competitor Michele Rougerie is handling the test riding chores. To keep
the center of gravity low. fuel is carried in a tank mounted underneath the engine. The tank is lined with .afuel cell to reduce the risk of fire. and is sculpted
to increase cornering clearance. Photos by Phillipe Oebarle .

The rear swing arm does its work through a single De Carbon Formula One
(auto racing) shock with a similiar set up in front. The Yamaha 750cc engine
functions as an integral part of the frame and has been strengthened with
mounting bosses. Aluminum dish wheels are used with stopping power via
Lockheed automotive disc brake units. Chrome Molybdenum steel has
been used throughout. The bike. minus fuel. weighs in at 288 pounds. •

Hub-center steering and leading-link forks make up the front suspension
geometry. Again. the shock and suspension units are attached directly to
the engine. Exhaust heat is ventilated through a series of vents in the
fairing/body shell. In addition. the underside of the body is coated with a
heat resistant material. A curved heat shield deflects the hot air from
circulating around the carbs. time and testing will tell if the package is a
competitive one.
